Tracy Subject: Fish Community and Benthic Macroinvertebrate Assessment of Mackey Creek Below the Discontinued Discharge from Metal Industries, Inc. (McDowell County, Catawba River Basin, Subbasin 30, NPDES Permit No. NC0057819) INTRODUCTION On March 25, 1998, biological monitoring was conducted at two sites on Mackey Creek, McDowell County, (Stream Classification Index No. 11-15-(3.5)), to investigate the impacts of a discharge from Metal Industries, Inc. Only two white suckers were collected below the discharge and the fish community was rated Poor; this contrasted to the diverse community above the discharge which was rated Good. Benthic m acroi nve rteb rates rated the stream Good above the discharge and Fair below (BAU 980415). In July 2000, the 0.01 MGD discharge from the metal plating facility was discontinued and the permit was rescinded in June 2001. As part of the 2002 Catawba River Basinwide Monitoring Program and as requested by the Asheville Regional Office, the fish and benthos communities were resampled to determine if there was any recovery following the discontinuance of the discharge. This memorandum summarizes the results from this monitoring. SITE DESCRIPTION Mackey Creek is a Class C tributary to the upper Catawba River and enters the Catawba River approximately 0.8 miles below the US 70 bridge crossing (Figure 1). The primarily forested watershed is in the Eastern Blue Ridge Foothills ecoregion; for fish community and benthos assessment purposes, the stream is considered to be in the mountains. The drainage area of the watershed is 7.7 square miles at the US 70 bridge crossing. At this site, there is still a discharge pipe which carries well water for a geothermal heat pump condenser for the refrigerating units from a nearby service station. This noncontact cooling water discharge enters the stream from a small pipe on the west bank and mixes immediately with water flowing over a concrete dam -like structure (Figure 2). The effluent is completely mixed with the receiving stream within a short distance below its discharge. A benthos sample was also collected at an upstream site at SR 1453. FISH METHODS A distance of 600 ft. below the US 70 bridge (beginning about 150 ft. below the dam) was sampled on April 29, 2002 following all methods (including physical -chemical and habitat assessments) in the existing North Carolina Index of Biotic Integrity (NCIBI) protocols (NCDENR 2001 a). The fish within the delineated stretch were collected using two backpack electrofishing units with each unit accompanied by one person netting fish. A seine was also used to effectively sample the boulder and cobble riffles. After collection, all readily identifiable fish were examined for sores, lesions, fin damage, and skeletal anomalies, measured (total length to the nearest 1 mm), and then released. Once the first 50 specimens of each species were measured, the remaining fish of each particular species were just counted and then also released. Those fish that were not readily identifiable in the field were preserved in 10% formalin and returned to the laboratory for identification, examination, and total length measurement. These fish were then deposited as voucher specimens with the North Carolina State Museum of Natural Science in Raleigh. 1 i-; US :�nw 42 �' � - _. 1l r�...�1J��� !)� f�.�.� / i / r ,. j � # � ��. ��'`�� 1 • � v � 4 `� � • �•'�--^r �� 1 �. - ♦ Z f.sa Lln :.E; + Creek � .�• 1413/ � f� t IL_ 7 0^ / 1412\ j�C l' e/ r • ��,, � �' % Ili• _�. � € j ! r1 z� reenF-= �• � � t � ,�'� tom"` l„"' Itt , \ `\� = • �7: r � , ,r, � � 'f _ � ,�s✓.�o - ri Cad , pa River '�`f IL 1302 ..1 • '� � �•�b"Rill .. .t..

Upstream view of Mackey Creek below US 70,McDowell County (A) and location and size of noncontact cooling water discharge from nearby service station (B), April 29, 2002. 2 BENTHOS METHODS Benthic macroinvertebrates were collected using the NC DWQ's standard qualitative (Full Scale) method at Mackey Creek below US 70 and using the EPT method at SR 1453. The standard qualitative sampling procedure is comprised of 10 composite samples, and includes 2 kicks, 3 sweeps, 1 leaf pack, 2 rock/ log washes, 1 sand sample, and visual collections. The EPT method consists of 1 kick, 1 sweep, 1 leaf pack, and visuals (NCDENR 2001 b). The purpose of these collections is to inventory the aquatic fauna and produce an indication of the relative abundance for each taxon. Organisms are classified as Rare (1-2 specimens, "R"), Common (3-9 specimens, "C"), or Abundant (z 10 specimens, "A" ). Several data summaries (metrics) can be produced from benthos samples to detect water quality problems. These metrics are based on the idea that unstressed streams and rivers have many invertebrate taxa and are dominated by intolerant species. Conversely, polluted streams have fewer numbers of invertebrate taxa and are dominated by tolerant species. The diversity of the fauna is evaluated using taxa richness counts; the tolerance of the community is evaluated using a biotic index. EPT taxa richness (EPT S) criteria have been developed by DWQ to assign water quality ratings (bioclassifications) for Full Scale and EPT samples. "EPT" is an abbreviation for Ephemeroptera + Plecoptera + Trichoptera, insect groups that are generally intolerant of many kinds of pollution. Higher EPT taxa richness values usually indicate better water quality. Bioclassifications for Full Scale samples are also based on the relative tolerance of the macroinvertebrate community as summarized by the North Carolina Biotic Index (NCBI). Both tolerance values for individual species and the final biotic index•values have a range of 0-10, with higher numbers indicating more tolerant species or more polluted conditions. EPT abundance (EPT N) and total taxa richness calculations also are used to help examine between -site differences in water quality. A Not Impaired rating is given if a stream is less than four meters wide and would receive a bioclassification of Good -Fair or better using DWQ EPT criteria developed for larger streams, if the stream is not in an undisturbed mountain watershed. RESULTS AND DISCUSSION FISH On April 29, 2002, the flow in Mackey Creek (based upon the USGS gauge at the Catawba River near Pleasant Gardens (SR 1221, McDowell County) was approximately 40% of the median flow (historical median flow -275 cfs, actual flow �_-113 cfs). On March 25, 1998, the flow was approximately 100% of the historical mean flow (historical monthly mean flow = 371 cfs, actual flow = 375 cfs). Much of the state in 2002 was in a severe to exceptional drought that had started in 1998. Instream and riparian habitats were of high quality in 2002 and in 1998 (habitat scores = 87 and 81, respectively) (Table 1). Colder water temperatures in 1998 than in 2002 accounted for the slight differences in dissolved oxygen concentrations and saturations; specific conductance and pH were similar for both dates (Table 2).

The most abundant species in this diverse community were the central stoneroller and the greenhead shiner. A majority of the species were represented by multiple age groups and there was no incidence of disease. The community was rated Good, NCIBI = 52 (Table 4). Although central stonerollers were fairly abundant and the trophic structure slightly skewed towards omnivores and herbivores (both indicative of some slight enrichment from upstream nonpoint sources), the fish community has recovered quickly from the toxic metals discharge. The fish community and its components are now typical of those found in mountain and foothills streams in the upper Catawba River basin. Table 3.

The benthic macroinvertebrate community also showed a marked improvement following removal of the .discharge. Different sampling techniques were used in 1998 and 2002, so direct comparisons of taxa richness values cannot be made. However, the bioclassification improved from Fair in 1998 to Good in 2002, as was found above the, discharge in 1998. EPT taxa richness doubled from 15 to 30. This increase was not attributable to the sampling method. Intolerant or long-lived taxa such as the stoneflies, Acroneuria abnormis and Paragnetina immarginata, and mayflies, Epeorus rubidus and Leucrocuta, were abundant, and were absent of rare in 1998. Water levels during the August benthos sampling were much lower than during the fish sampling in spring. The reduced flow may have had some effect on the benthos. The higher gradient, upstream site at SR 1453 was only three meters wide, probably due to the drought conditions, so it was not assigned a bioclassification. It was considered Not Impaired because a rating of Good -Fair would be given, based on the EPT taxa richness value of 23, if it were a larger stream. This site had an Excellent rating in 1992 and a Good rating in 1997. The low water levels reduced the edge habitat available.' A layer of silt over the rocks was noted, as well as accumulations of sand in slow areas. [Note: The source of sediment has been identified as originating from land disturbing activities on property on Guy Road near the mouth of Knife Branch, a small tributary to Mackey Creek. The land quality violations have lead to enforcement actions against the property owner.] Table 5. Summary of benthos sampling results for two sites on Mackey Creek, McDowell County, August 2002.

(McDowell County, Catawba River Basin, Subbasin 30, NPDES Permit No. NC0057819) INTRODUCTION On March 25, 1998, biological monitoring was conducted at two sites on Mackey Creek, McDowell County, (Stream Classification Index No. 11-15-(3.5)), to investigate the impacts of a discharge from Metal Industries, Inc. Only two white suckers were collected below the discharge and the fish community was rated Poor; this contrasted to the diverse community above the discharge which was rated Good. Benthic m acroi nverteb rates rated the stream Good above the discharge and Fair below (BAU 980415). In July 2000, the 0.01 MGD discharge from the metal plating facility was discontinued and the permit was rescinded in June 2001. As part of the 2002 Catawba River Basinwide Monitoring Program and as requested by the Asheville Regional Office, the fish and benthos communities were resampled to determine if there was any recovery following the discontinuance of the discharge. This memorandum summarizes the results from this monitoring. SITE DESCRIPTION Mackey Creek is a Class C tributary to the upper Catawba River and enters the Catawba River approximately 0.8 miles below the US 70 bridge crossing (Figure 1). The primarily forested watershed is in the Eastern Blue Ridge Foothills ecoregion; for fish community and benthos assessment purposes, the stream is considered to be in the mountains. The drainage area of the watershed is 7.7 square miles at the US 70 bridge crossing. At this site, there is still a discharge pipe which carries well water for a geothermal heat pump condenser for the refrigerating units from a nearby service station. This noncontact cooling water discharge enters the stream from a small pipe on the west bank and mixes immediately with water flowing over a concrete dam -like structure (Figure- 2). The effluent is completely mixed with the receiving stream within a short distance below its discharge. A benthos sample was also collected at an upstream site at SR 1453. FISH METHODS A distance of 600 ft. below the US 70 bridge (beginning about 150 ft. below the dam) was sampled on April 29, 2002 following all methods (including physical -chemical and habitat assessments) in the existing North Carolina index of Biotic Integrity INCOI) protocols (NCDENR 2001a). Thle fish v.,ithin the delineated stretch were collected using two backpack electrofishing units with each unit accompanied by one person netting fish. - A seine was also used to effectively sample the boulder and cobble riffles.

Once the first 50 specimens of each species were measured, the remaining fish of each particular species were just counted and then also released. Those fish that were not readily identifiable in the field were preserved in 10% formalin and returned to the laboratory for identification, examination, and total length measurement.

The standard qualitative sampling procedure is comprised of 10 composite samples, and includes 2 kicks, 3 sweeps, 1 leaf pack, 2 rock/ log washes, 1 sand sample, and visual collections. The EPT method consists of 1 kick, 1 sweep, 1 leaf pack, and visuals (NCDENR 2001 b). The purpose of these collections is to inventory the aquatic fauna and produce an indication of the relative abundance for each taxon. Organisms are classified as Rare (1-2 specimens, "R"), Common (3-9 specimens, "C"), or Abundant (>_ 10 specimens, "A").' Several data summaries (metrics) can be produced from benthos samples to detect water quality problems. These metrics are based on the idea that unstressed streams and rivers have many invertebrate taxa and are dominated by intolerant species. Conversely, polluted streams have fewer numbers of invertebrate taxa and are dominated by tolerant species. The diversity of the fauna is evaluated using taxa richness counts; the tolerance of the community is evaluated using a biotic index. EPT taxa richness (EPT S) criteria have been developed by DWQ to assign water quality ratings (bioclassifications) for Full Scale and EPT samples. "EPT" is an abbreviation for Ephemeroptera + Plecoptera.+ Trichoptera, insect groups that are generally intolerant of many kinds of pollution. Higher EPT taxa richness values usually indicate better water quality. Bioclassifications for Full Scale samples are also based on the relative tolerance of the macroinvertebrate community as summarized by the North Carolina Biotic Index (NCBI). Both tolerance values for individual species and the final biotic index values have a range of 0-10, with higher numbers indicating more tolerant species or more polluted conditions. EPT abundance (EPT N) and total taxa richness calculations also are used to help examine between -site differences in water quality. A Not Impaired rating is given if a stream is less than four meters wide and would receive a 'bioclassification of Good -Fair or better using DWQ EPT criteria developed for larger streams, if the stream is not in an undisturbed mountain watershed. RESULTS AND DISCUSSION FISH On April 29, 2002, the flow in Mackey Creek (based upon the USGS gauge at the Catawba River near Pleasant Gardens (SR 1221, McDowell County) was approximately 40% of the median flow (historical median flow -275 cfs, actual flow =113 cfs). On March 25, 1998, the flow was approximately 100% of the historical mean flow (historical monthly mean flow = 371 cfs, actual flow = 375 cfs). Much of the state in 2002 was in a severe to exceptional drought that"had started in 1998. Instream and riparian habitats were of high quality in 2002 and in 1998 (habitat scores = 87 and 81, respectively) (Table 1). Colder water temperatures in 1998 than in 2002 accounted for the slight differences in dissolved oxygen concentrations and saturations; specific conductance and pH were similar for both dates (Table 2).

The benthic macroinvertebrate community also showed a marked improvement following removal of the discharge. Different sampling techniques were used in 1998 and 2002, so direct comparisons of taxa richness values cannot be made. However, the bioclassification improved from Fair in 1998 to Good in 2002, as was found above the discharge in 1998. EPT taxa richness doubled from 15 to 30. This increase was not attributable to the sampling method. Intolerant or long-lived taxa such as the stoneflies, Acroneuria abnormis and Paragnetina immarginata, and mayflies, Epeorus rubidus and Leucrocuta, were abundant, and were absent of rare in 1998. Water levels during the August benthos sampling were much lower than during the fish sampling in spring. The reduced flow may have had some effect on the benthos. The higher gradient, upstream site at SR 1453 was only three meters wide, probably due to the drought conditions, so it was not assigned a bioclassification. It was considered Not Impaired because a rating of Good -Fair would be given, based on the EPT taxa richness value of 23, if it were a larger stream. This site had.an Excellent rating in 1992 and a Good rating in 1997. The low water levels reduced the edge habitat available. A layer of silt over the rocks was -noted, as well as accumulations of sand in slow areas. [Note: The source of sediment has been identified as originating from land disturbing activities on . property on Guy Road near the mouth of Knife Branch, a small tributary to Mackey Creek: The land quality violations have lead to enforcement actions against the property owner.] 5 Table 5.

(s): 6 April 1999 Time Reported: 6 April 1999, approximately 3:30 p.m. Counties: McDowell Stream or Lake: Mackey Creek, CAT 7-22 Location: Mackey Creek, immediately below bridge at U.S. 70 downstream to the confluence with the Catawba River at river km 238.5. Type of Investigation: Formal Observations: Approximately 125 dead silver redhorse. Some distressed fish. Effluent flowing from PVC pipe into Mackey Creek immediately below U.S. 70 bridge. Type of Pickup: Partial; to obtain average weight for cost estimate. Additional Comments: No dead fish found above U.S. 70 or in tributary creek, Stillhouse Branch. No other fish of any type seen in creek alive or dead. Stream segment appeared to be severely degraded. EXPENSES Total Subsistence: Miscellaneous: Douglas A. Besler: Mallory Martin: None None 13 hours, 40 miles 2 hours, 20 miles OBSERVATIONS REPORTED On 6 April 1999 I was notified of a resident reporting a fish kill in progress on Mackey Creek (CAT 7-22), a tributary to the Catawba River at river km 238.5. I responded to the resident, Joyce McKinney, and met her on site. Upon initial investigation of the scene it was discovered that dead and dying fish were found immediately below the U.S. 70 bridge downstream to the confluence with the Catawba River. I then contacted Liz Dickson, DWQ, and reported the fish kill to her. Liz advised me that DWQ would proceed with an investigation and to begin estimating the extent of the kill. Mackey Creek Fish Kill Report 2 4/6/99 e No dead or distressed fish were found upstream of U.S. 70 or in the tributary to Mackey Creek, Stillhouse Branch. Immediately below the U.S. 70 bridge I noticed a clear effluent flowing from a white PVC pipe directly into Mackey Creek. Over 100 silver redhorse (Moxostoma anisurum) were found dead along the approximately 800 in downstream to the confluence with the Catawba River. Several silver redhorse were found in the process of dying and could readily be captured by hand. All dead fish appeared to have died within the prior 24 hours. Only adult silver redhorse >350 min total length were found. No other species of fish were noticed alive or dead; the creek appeared to have been substantially impacted over time. Many of the dead silver redhorse had free -flowing eggs and milt and probably moved up the tributary to spawn. After assessing the situation with Liz Dickson, I then contacted Mallory Martin, NCWRC, and he met me on site with the necessary equipment to estimate the size and number of dead fish. Mallory began at the U.S. 70 bridge and collected the first 10 silver redhorse encountered downstream and enumerated the remainder. I began at the confluence with the Catawba River and repeated the exact process upstream until I encountered Mallory. The total number of silver redhorse enumerated was 128. Several silver redhorse were seen floating into the Catawba River and it is likely that our estimate was substantially low. Total lengths (mm) and weights (g) were recorded for each fish collected. The average weight of the 20 fish collected were used to estimate the total weight of all silver redhorse killed and provide the fish cost estimate. Replacement costs for fish were derived from Investigation and Valuation of Fish Kills (American Fisheries Society special Publication 24, 1992). On 8 April 1999 I returned to the site and walked the entire length of Mackey Creek from the U.S. 70 bridge downstream to the confluence of the Catawba River. Only a few dead fish were spotted and appeared to be over 24 hours old. I collected two dead silver redhorse, one northern hogsucker (Hypentelium nigricans), two central stonerollers (Campostoma anomalum), and two bluehead chubs (Nocomis leptocephalus). These specimens were sent to Mark Hale, DWQ, for tissue analysis. V Field Investigation Costs INLAND FISHERIES Name Hours Salaries Mileage Subsistence Misc.

This workbook (STREAMS.XLS) is one of three for estimating fish kill totals and values. The others are for open water situations (LAKES.XLS), and for wide streams and rivers (RIVERS.XLS). The following mathematical and statistical criteria and limitations apply to using this workbook: This workbook can be used for streams with complete access (pg 19) or incomplete access (pg 21). Single day pick up only. Multiple day pickups must be treated as series of single days (pg 30). Subsampling of a species or segment (pg 51) must be expanded prior to entering data in the workbook. Corrections for drifting fish (pg 24) must be made prior to entering data in the workbook. Expanded numbers of fish are generated by multiplying the total count by an expansion factor (pg 19). Expanded estimates are for all species combined, not for individual species or inch -classes. If you want more detailed information you must do so in a different workbook. Rename the file for the stream and year using the "File/Save As..." command. The first 6 digits should be for the stream name, the last 2 digits for the year (e.g., stony97.xis) Complete the Stratum 1, (Stratum 2) and Statistics worksheets Select the appropriate sampling method for narrow streams (pg 18-25). c In the blue cell to the right type a "C" (Complete Access method) or an "I" (Incomplete Access method).

CrL �i= T¢% Drjc.�rSS ( E-Mail: Fish Dill Under Investigation By RAGAN ROBINSON :< Staff Writer Two Pleasant Gardens boys made a grue- some discovery Tuesday as they waded through Mackey Creek — a creek bed full of dead sucker fish. Adam McKinney and his cousin, Jessie McKinney, were wading upstream when they began to notice the fish lying on the bot- tom. "I counted about 50," said Adam McKinney. "They go up through there to spawn every year and then go back but they're not getting back so well." His mother, Joyce McKinney, took one look at the mess before calling N.C. Wildlife Resources and the Environmental Protection Agency. "It's horrifying when you can't even wade a clear stream like this without having to worry what killed the fish," she said. "I just Officials will try to determine what caused a fish kill in Mackey Creek. (Photo by Bonnie Byrd) wonder what could be in this water." Doug Besler of N.C. Wildlife Resources made a trip to P.G. to find out whether the matter warranted investigation by the N.C. (See FISH, Page 2A) Fish Kill Under Investigation (Continued from Page 1A) Division of Water Quality. He said it is possible that the fish could be dying as the result of a natural occurrence, but it was high- ly unlikely. "Usually when you have some- thing localized like this, it's some- thing someone's put in the water," he noted. The fish he saw in the water were Golden Redhorses, said Besler, which are sucker fish that feed from the bottom of the creek bed. The Division of Water Quality will assess any civil penalties or fines once they determine whether anything was put into Mackey Creek.

Although combinations of copper/lead and copper/cadmium an wTlisew in their effects on algae, combinations of copperfnick3d act nctgistically. Synergism has also been noted for combinations of copper d iiouride, copper and manganese, and copper and zinc. Many algal species can adapt to high copper levels W water. Tolerant W accumulate high levels (600 mg kV-1 dry weight) of copper while still awing and 4ividing (Stokes, 1975), thereby increasing the amount of Pper in the food chain in polluted waters. Ernst (1975) found no resistant zymes specific to tolerant populations of mosses and higher Plants.Inc nested that tolerance depended on the presence of compkxing agents rich were not organic acids, however, some species can produce a metal- hionein-like protein for detoxification. invertebrates , per is highly toxic to most ft 6lwater and n m"W invertebrates. LC,c's generally less than 0*5 rag L-1, though they may range from 0.006 to 225A mg L-L under certain conditions. Toxicity is generally greater is sl�water than in marine waters, reflecting the relative proportion of the do free copper ion in solution. Water hardness plays a role in determining tazicity. The LCm for the gochaete Tub fex (why -ex increased by a factor of 150 when water hard -increased from 0.1 to 261 mg CaCO3 L ' (Brkovi&Papovic and Popa- :, 1977). Simiiady, toxicity of Daphnia magna was directly related to ivities of cationic Cue , CuoH+ and Cuz(O'H)J+ over wide ranges in total r, dissolved copper, and inorganic chelator concentration (Andrew. et . 1977).

Furthermore sod copper from solution, .8 and 1the respecti !reby decreasing availability of copper to the test organisms. Some species can adapt to high levels of copper. Brown (1976) reported 1t the 48h. Lqo for the isopod Asellus meridicanus was 2.5 mg ;-' for imals collected from a highly polluted river and 1.2 mgL-' forthose from s polluted sites. Growth of the tolerant isapods was not influenced by peer -levels which restricted non -tolerant animals and their pm8eay nearly; 5udo and Aiba (19") demonstrated that the mean inhibitor? In general, sensitivity is inversely retatedt to sae agef sun ul auu uw. X % -v%L ration, and population density were directly correlated with LC3o s in the copepod Acartia tonsa (Sosnowsld et al., 19779). Although this latter study suggested that sublethal cflects occur at or slightly above ambient levels in the sea, the ability of wild populations to adapt to copper probably MW- mims such effects. Sosnowski and Gentile (197S) concluded that LC -%data for wild populations were significantly more variable than those for cultured stocks. While changes in food supply under natural conditions probably E account for these differences, the toxicity of copper also depends an the vD genetic strain of animal under investigation. EZ Treatment of the polychaeteEudisiyltavaneoveriwith 0.010 mgCu. L 1 caused a shortening and clubbing of the pinnules on the gills (Young et aL, 1981). There was loss of cellular adhesion in the gills -and sMwtaral derange- n meat that lead to cell necrosis and death. Exposure of the whelk Busjvon cat a ictdafvm to copper in dilated efferent blood sinuses and blood lacunae in the leaflets of the gills (Better and Yevich,1975), There was a progxmve increase in the swelling of the leaflets, hallowed by necrosis and sloughing of the epithelium of the osphrad iam and gills. George et al. (1978) suggested M that oysters Ostrea edtdis could compartmentalize capper, following sub. iD lethal exposures. It was concluded that toxicity is reduced by active uptake o from Ecrum into granular amoebocytes. These cells may contain as much as 13,OW mg k-1 copper. Lo ;Dish tD 1D Copper is usually more toxic to freshwater fish than any other heavy metal except mercury (Eigare 541 LC o!s range from 0.017 to 1.0 mg L-1 under most conditions. However, unusually high water hardness may increase We gbh LC50 to 3.0 mg L 1. Copper is much less toxic to marine fish due to the high complexiug capacity of salt water. Approximately 30% mortality oeourrud in. mummicbog following exposure at 8.0 mg Cu L ' for 96h 23 (Eisler and Gardner,1973). Acute toxicity to freshwater fish depends largely on water hardness (Figures 54, 5-5). Ionic capper (Cunt) and ionized hydroxides (CuOH+, Cu2oU2+) are most toxic, with a combined 96h LC5c of 0.00009 -0.23 mg L ', At low water hardness (12 mg L 1) the incipient Lethal concentration (1LC)• of dissolved Cu to rainbow trout was not affected by a change in b alkalinity of 10 - 50 mg 1.71(Miller and Mackay,1980). However, the same change in alkalinity in hardwater (98 mg L c) iesulted in a l .8-fold increase in the iLC. Toxicity of combinations of Cur+fCuOH+/Cur and H} were antagonistic to rainbow trout at pH <SA, whereas at pH > 5.4 there was synergissm betwem.capper toxicity and pH (Miller and Mackay, 1980). 8y-nergistic have also been noted for combinations of Cu/Cd/Za. r� effects 95 •n in some is thtrty- In& and p i8:345— oomplex- 309-315.

Anlagonistic effects occur following aamplexation with or- ganic material, sewage and CaC 0;. Inter -species variability may account for a 30-fold difference in the toxicity of copper under constant test conditions. Some of the more send- tivf• species include fathead minnows, guppies, and golden shiner (Smith and Heath, 1979; Pickering and Henderson, 1966). Newly -hatched alevins of steelhead trout were less sensitive than the swim -up and parr stages (Chapman, 1978). However, in chinook salmon, alevins and parr showed a equal sensitivity to copper. Dixon and Sprague (1981) found that lethal tolerance by rainbow trout increased 60-106% fallowing exposures to 29 - 59% of the mean incipient lethal limit. However, acclimation to copper was not permanent. Exposure to chroniolsablethal levels (0.02-0.2 mg L-1) of cooper r*- daces survival, growth, and rate of reproduction in a variety of species. In soft water, fecundity and egg survival may be inhibited at conoentrations as lov as 0.004 mg L L. Furthermore, the hetuatocrit for a range of species increases with copper levels in the environment. Oxygen consumption, blood pH, and eaetgy expenditure may also increase. whereas feeding rate may decline (Waiwood and Beamish, 1979; Utt et at., 1976). Sublethal exposures also result in behavioural changes, such as decreased concealmeat .,,,a ahit;ry to nrirnt This partially reflects depression in olfactory response following treatment with copper. There is also a marked change in preferred temperature, which could in turn produce an immediate decrease in sur- viud. Although not demonstrated, it is likely that salinity preferenda in fish would Change, again reducing survival. Copper ions precipitate gill secretions, causing death by asphyxiation ('Tsai, 1979). There is also an impairment of haem4opoetic tissue in gill filaments which results in a reduction of oxidative activity. Necrotic kidney cells, fatty degeneration of the liver, and brain hemorrhage have been reported for acutely exposed fish. Eisler and Gardner (1973). found that nuclei of affected squamous epithelial cells of the oral cavity in mummi- chV appeared pyknotic and hyperchromatic. There was also a marked increase iu the number of dividing cells in the respiratory epithelium. These changes are largely similar to those producedby salts of other heavy metals. Humans Copper is not acutely toxic to humans. This is due to the interutodiate coordinate character of copper between hard and soft acids. Hence copper seldom interferes with sulfur -containing proteins. By contrast the moderate toxicity to aquatic animalsresults from its sequestering and precipitating the. essential carboxylic acids. In some. instances, copper deficiency in humans iraitates chronic copper intoxication. There is no indication that copper is References AWL Y Y„ N.B. Bhosle, and A.G. Untawale. 1978.
