Evaluation of Fentonʼs Reagent Toxicity to Biomphalaria Alexandrina Snails

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, there was not a pronounced enhancement or inhibition. In conclusion, certain Fenton concentrations can be used as inexpensive and environmentallyfriendly disinfecting agents as they are safe on snails which are good bioindicators of toxicity.
