Organophosphate pesticides (OPs) are commonly used in conventional agriculture and whilst considered to be less persistent than the lipophilic and bioaccumulatic organochlorine pesticides they have replaced including DDT and dieldrin, they are associated with a number of negative health effects.
After organochlorine pesticides were found to bioaccumulate and cause ecosystem disturbances, the relative chemical instability and rapid degradation characterizing organophosphate pesticides (OPs) led to their increasing use in the agrochemical industry.
Two sources of microorganisms were studied: agricultural soils with MP degrading potential, due to the fact that they were periodically treated with organophosphate pesticides and an organic solid residue from fruit wastes.

According to police investigations, the amount of the organophosphate pesticide methamidophos found from the dough and fillings of dumplings which the family consumed turned out to be more than 3,000 parts per million, the officials said.
