Environmental Fate - Ecotoxicology - Human Health - A to Z Index - Home
SUMMARY
Sulfluramid is an insecticide without EU regulatory approval for use. It has a low aqueous solubility, is quite volatile and is non-mobile. There are gaps in environmental fate knowledge but is known to be resistent to microbial degradation and photolysis. It has a low mammalian toxicity but there is some concern regarding its potential for bioaccumulation. It is not highly toxic to birds but is more of a concern for aquatic species and honey bees.
