安全性と法規制
| 毒性の概要 | Diethylthiophosphate (DETP) induces DNA damage only in the hepatic cell lines, and this effect could be related to a secondary non-diffusible metabolite generated by the activity of P450 enzymes since P450 enzyme inhibitors also inhibited the induction of DNA damage in hepatic cells. This organophosphorous (OP) metabolite has shown some toxicity in human peripheral blood mononucleated cells (PBMC). DETP is a cytotoxic compound in human PBMC. A relationship between urinary levels of DETP and the number of sperm susceptible to chromatin alteration has been reported among rural agricultural workers. In addition, a correlation between the frequency of aneuploidy in sperm and the levels of DETP in urine was identified in a rural population exposed to OP pesticides, indicating that the potential for genotoxicity following OP exposure may depend on the type and quantity of specific metabolites produced, such as DETP.
