Chlorpyrifos is a commonly used pesticide of organophosphate group, which causes toxicological effects in non-target organisms especially fish and frogs. In the present study, the genotoxicity of sublethal concentrations of chlorpyrifos was observed in the erythrocytes of common Indus valley toad, Bufo stomaticus, using the Alkaline Single-Cell Gel Electrophoresis (Comet) assay. In the first step, acute toxicity of chlorpyrifos was evaluated by exposing the tadpoles to high concentrations of the pesticide. The acute LC 50 value of chlorpyrifos, calculated by Trimmed Spearman-Karber (TSK) in static bioassay, was found to be 930.0 µg/L. On the basis of acute LC 50 value, the tadpoles were exposed to three sublethal concentrations (155, 233 and 465 µg/L) of chlorpyrifos for 96 h. Blood cells were collected at every 24 h interval and were subjected to the Alkaline Single-Cell Gel Electrophoresis assay. The observed DNA damage was concentration and time-dependent, and those levels of DNA damage in between the tested concentrations and times were significantly different (p < 0.05). The tadpoles exposed to different concentrations of chlorpyrifos also showed different morphological abnormalities. It was concluded that chlorpyrifos is a genotoxic pesticide causing DNA damage in Bufo stomaticus.

“…Chlorpyrifos is also one of the major pesticides detected in fishery products (Sun et al 2006). Sun and Chen (2008) analyzed marketable fish samples for chlorpyrifos residues and found detectable residues in farmed as well as wild fishes. These authors reported that chlorpyrifos in the farm fish were positively related to its existence in fish feed.…”

Chlorpyrifos is the most common insecticide in freshwater ecosystems, and detected in agricultural and fishery product. In this study, Oreochromis niloticus were exposed to 5, 10 and 15 ppb sublethal concentrations of chlorpyrifos in order to determine the oxidative stress response in liver. Acetylcholinesterase (AChE) activity was significantly inhibited. Superoxide dismutase activity (SOD) increased after 15 days of chlorpyrifos treatments at all concentrations (146.95%, 53.04%, 208.70%, respectively). Malondialdehyde levels were higher than that of the control level after 15 days of 5 ppb (95.65%), 10 ppb (69.56%) and 15 ppb (252.17%) chlorpyrifos treatments. Malondialdehyde levels were also increased ranging from 59.09%, 113.63% to 195.46% after 30 days of 5, 10 and 15 ppb chlorpyrifos exposures. Glutathione S-transferase activity decreased except for 15 days low concentration exposure. Catalase (CAT) activity decreased while there is no significant alteration in glutathione peroxidase activity. After recovery period, the low concentration group of chlorpyrifos provided a protection in AChE activity during recovery, but fish were observed to be unable to overcome the inhibition of AChE activity at high concentration groups. CAT activity remained reduced, SOD activity increased whereas the other biochemical parameters recovered to control levels. Results of this study suggest that chlorpyrifos induces oxidative stress in the liver of O. niloticus and this effect is not related with anti-acetylcholinesterase activity of pesticide.
