Abstract:
Fentonʼs reagent is considered a promising disinfecting agent as it has antimicrobial activity. In the present study, effective antifungal Fenton concentrations were investigated on Biomphalaria alexandrina snails as bio indicators of toxicity. Generally, they resulted in low mortality rate of snails, as only 20% mortality was recorded after 60 min of exposure. Also the activities of two antioxidant enzymes; catalase (CAT) and superoxide dismutase (SOD) in snails’ tissues were investigated at different time intervals. Although the activities of both enzymes were different from control group, t

Recent legislation in the United States is placing emphasis on the removal of priority pollutants and aquatic toxicity from industrial wastewaters. A protocol has been developed to select candidate technologies for specific effluent objectives. Wastewaters which are non-biodegradable and toxic are designated for source treatment.

ABSTRACT Recent advances in oil toxicity research may well alter the way oil spill response decisions are made. Those responding to spills should be aware of the limitations surrounding the use of acute toxicity data to predict even short-term oil effects. Many animals previously classified as tolerant of short-term oil exposure, such as fish eggs and benthic organisms, are just as or much more sensitive than pelagic fishes to chronic exposures. Toxicity bioassays proved to be of limited value in predicting the long-term damage from the Exxon Valdez oil spill because such toxicity information
