Symptoms and implications of selenium toxicity in fish: the Belews Lake case example.
Belews Lake, North Carolina was contaminated by selenium in wastewater from a coal-fired power plant during the mid-1970s, and toxic impacts to the resident fish community (20 species) were studied for over two decades. Symptoms of chronic selenium poisoning in Belews Lake fish included, (1) telangiectasia (swelling) of gill lamellae; (2) elevated lymphocytes; (3) reduced hematocrit and hemoglo...
متن کاملTeratogenic effects and monetary cost of selenium poisoning of fish in Lake Sutton, North Carolina.
Selenium pollution from coal ash wastewater was investigated in Lake Sutton, NC. This lake has been continuously used as a cooling pond for a coal-fired power plant since 1972. Historic and recent levels of contamination in fish tissues (14-105µg Se/g dry weight in liver, 24-127 in eggs, 4-23 in muscle, 7-38 in whole-body) exceeded toxic thresholds and teratogenic effects were observed in fish ...
متن کاملFish Poisoning: A Problem in Food Toxication
INTEREST IN POISONOUS FISHES has intensified greatly in recent years. World Wat II brought many Americans and Europeans to tropical areas of the world where fish poisoning is common. Also, interest in the welfare of native populations of the Pacific islands has developed widely, and there is an impression that fish poisoning is increasing. In spite of an extensive literature, there is considera...
متن کاملThe effect of dietary selenium on growth performance, Carcass Composition, and blood profile of farmed juvenile beluga (Huso huso)
This study was designed to compare the effects of different levels of mineral selenium in diet on growth performance, some blood indices and juvenile beluga carcass composition (Huso huso) within 10 weeks. For this purpose, a number of 315 fry with an average weight of 15.66 ± 0.77 grams were stocked in the twenty-one 500-liter fiberglass tanks (15 per each). Seven diets containing different le...
متن کاملSelenium compounds for fish health: An update
Oxidative stress has become an important subject for terrestrial and aquatic toxicology. The trace element selenium has been demonstrated in chemo-prevention and drug-resistance through reduction of oxidative stress. Selenium compounds could prevent damage to the unsaturated fatty acid of subcellular membranes by lipid peroxidation induced by free radicals in fish.
