Definition of chlorfenvinphos:
Chlorfenvinphos is an insecticide used to control insect pests on livestock. It was also used to control household pests such as flies, fleas, and mites. The pure chemical is a colourless liquid with a mild odour[1].
This is the common definition for chlorfenvinphos, other definitions can be discussed in the article

Chlorfenvinphos was introduced in 1963 in the U.S.A., where it was used until 1991. No information is available about the volumes in which it was used.

Chlorfenvinphos enters the environment from run-off after rainfall and leaching from hazardous waste sites. After it has leached, it may be present in the soil and underground water. It has a water solubility of 130mg/l and a moderate tendency to adsorb to particles. In water it is relatively stable, (it is only slowly hydrolysed), but some biodegradation might occur by micro-organisms.

It may have a low to moderate tendency to bioaccumulate, however no experimental data on fishes are available. There also isn't any information available on its potential to biomagnify[1].

It is very toxic for fishes: acute toxicity concentrations range, depending on the species, between 25 µg/l and 1 mg/l. Zooplankton are even more vulnerable, some species don't survive short exposure to concentrations above 0.4 µg/l[2].
