“…Mucus secretion was stimulated by copper. This has been reported earlier for copper (Benedetti et al, 1989;Khangarot and Tripathi, 1991) as well as for many other pollutants, e.g. crude petroleum, heavy metals such as lead or mercury, or water acidification (Burton et al, 1984;Iger, 1992;Lock and Van Overbeeke, 1981;Wendelaar Bonga et al, 1990).…”

“…Necrotic process es reflect accidental cell death (Wyllie, 1981), and thus likely represent direct toxic effects of the copper on the superficial cells. Copper was also shown to induce degen eration of the upper cell layers of the skin of the brown bullhead and of the branchial epithelial cells of the catfish (Benedetti et al, 1989;Khangarot and Tripathi, 1991). Necrosis of pavement cells occurred also after exposure to zinc or cadmium (Somasundaram, 1985;Iger, 1992) as well as after exposure to low pH water (Wendelaar Bonga et al, 1990).…”

Cellular responses in the skin of carp (Cyprinus carpio) exposed to copper

et al. 1994

The skin o f carp, Cyprinus carpio, was exam ined at the ultrastructural level after exposure to 1.6 juM (100 fi% I"1) of copper for different periods, up to 43 days. D uring the first 7 days, the skin surface became highly undulating and covered by a web o f glycocalyx and am orphous mucus. At this period, degenerative pavem ent cells (both apoptotic and necrotic) were com m on. D uring the whole period filament cells from the outer epiderm al layers were active in synthesizing secretory vesicles o f high electron density. M itotic activity was enhanced, and was located m ainly in the vicinity o f club cells. M ucous cells differentiated close to the skin surface, became elongated and synthesized highly electron-dense, probably serous, m ucosom es. The latter showed peroxidase activity. M any leucocytes invaded the skin, and chloride cells ap peared close to the epiderm al surface. M erkel cells were depleted o f their secretory vesicles during the first week of copper exposure, but recovered afterw ards. In the dermis, fibroblasts became m ore active in the synthesis and secretion o f collagen. The pigm ent in the melanocytes was dispersed in the first weeks, but this reversed tow ards the end o f the experiment. These changes reflect the sensitivity o f the skin o f fish to w aterborne copper. They are com parable to the effects o f stressors such as cadm ium , lead, or acid water.

“…In recent years, the remobilization of metals by synthetic anthropogenic chelating agents has received much attention. The literature reported a number of chelators that have been used for chelate-induced hyper accumulation (Khangarot and Tripathi [12]). Natural compounds, such as fulvic acid, are known to be effective chelating agents of heavy metals (Karuppasamy [13]).…”

The effect of fulvic acid on cadmium (Cd) toxicity, the impact on fish immunological, and haematological changes in Nile tilapia (Oreochromius niloticus) were studied. The fish (100±10g) were exposed to 10 ppm Cd alone or with 0.1, 0.2 and 0.3 ppm for 15 and 45 days. Cd exposure reduced significantly (P<0.04), for example the erythrocyte count (RBCs), haemoglobin content (Hb), haematocrit value (Hct), mean cell haemoglobin (MCH) and mean cell haemoglobin concentration. These parameters were improved when fulvic acid was applied with Cd. The values of RBCs, Hb, Hct, MCH and MCHC were increased significantly in the control fish group. The addition of fulvic acid to Cd contaminated medium considerably reduced metal absorption and accumulation in fish tissues, while metals in water and faeces increased. Fish exposed to Cd alone accumulated 2.15 and 5.970 mg Cd/g dry weight in the liver tissue over 15 and 45 days, respectively. Cd reduced significantly to 1.292 and 4.16.; 0.92 and 3.791; and 0.41 and 2.43 mg Cd/g dry weight tissue in fish exposed to 0.1, 0.2 and 0.3g fulvic acid/L over 15 and 45 days, respectively. Similar trends were observed in gills and musculature.

“…Many factors such as environmental and physiological are known to influence fish hematology; these include stress due to capturing, transportation, sampling, age and sex [17]. The decrease in the RBC to hemolytic crisis that results in severe anemia in fish exposed to copper pollutant [18] or due to reduction of heamoglobin synthesis affected by pollutants metals. The decrease in both Hb and PCV in this work indicates that effluent exposed fish are anaemic.…”

ABSTRACT-Ramgarh taal is an important water body of Gorakhpur, U.P, India, which received untreated effluents from different sources of Gorakhpur city. The aim of the present study was to evaluated the toxic impact of these effluents on water quality of water and its toxic effect on fish population present in this lake with two sets of experiments (1) Fish caged in pollution free water i.e. control group and (2) Fish directly caught from different sites of water body. The effluents discharged in this water body caused significant alterations in pollution parameters of water and significantly altered the biochemical profile (total amino acid levels increased while total protein, Glycogen and nucleic acid levels decreased from the levels of control group) and hematological parameters (PLTs, WBCs, RBCs, HGB, HCT, MCV, MCHC etc) decreased from the levels of control group. Seasonally variations in Physico-chemical parameters (Temperature, pH, DO, BOD and COD) of water body also measured. Which were much higher than the tolerance limit recommended by General standard by Central Pollution Control Board of India.
