Overview


Leptophos is a highly toxic organophosphate pesticide that is no longer registered for use in the United States and its health effects result from cholinesterase inhibtion (#Scorecard and #INCHEM). It is absorbed dermally, through inhalation or ingestion and, like most Pesticides, is most dangerous to the workers who handled it (#INCHEM).
