exposure is ubiquitous, and experimental data and evidence from accidental poisoning in humans indicate that it is neurotoxic.

The United States Environmental Protection Agency has indicated that organophosphate pesticides
are dangerous not only to humans but also to bees and wildlife.
Acute toxic effects of organophosphate pesticides
on killifish fish (Aphanius dispar) juveniles.
(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.

Chlorpyrifos is an organophosphate pesticide
that is characterized as a strong toxin.
Methamidophos was later detected in the dumplings, but Chinese authorities have denied the organophosphate pesticide
residue came from the Chinese factory that produced the dumplings.
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.
