Definition of ethyl O-(p-nitrophenyl) phenyl phosphonothionate (ENP):
Ethyl O-(p-nitrophenyl) phenyl phosphonothionate is an organic compounds with a phosphorous group. It is used as a pesticide. At room temperature it appears as a yellow powder, but at temperatures above 35 °C it becomes a brown liquid.
This is the common definition for ethyl O-(p-nitrophenyl) phenyl phosphonothionate (ENP), other definitions can be discussed in the article

Formula
C14H14NO4PS

Ethyl O-(p-nitrophenyl) phenyl phosphonothionate has been used as an insecticide on a variety of plants against a wide range of insects. As EPN is expected to be released released to the environment primarily during aerial and ground spraying of various agricultural crops. When released to in water or the soil it is expected to be degraded rapidly (in less than a month) by hydrolysis and oxidation. Due to it's low water solubility it is expected to be relative immobile in the soils where it's sprayed upon. In water it is also mostly adsorbed to suspended particles and the sediments. It has a low volatility, causing only small amounts to evaporate to the atmosphere where they are degraded rapidly. [1]

EPN has some tendency to bioaccumulate, but only when biota are continuously exposed, since EPN can be excreted rapidly.[2]

It is a highly toxic compound for crustatians, as concentrations above 0,5 µg/l can already be lethal. Fish are less vulnerable as below 20 µg/l are tolerated, and some fish species can even survive in concentrations above 1 mg/l. [3]
