MCPP is mainly used to control weeds around cereal crops, apples and pears. The release of mecoprop to the environment will be primarily from its application as a herbicide, but also potentially from its manufacture, transport and storage. There are no natural sources[1] .
In water is has a low solubility of 0.734 g/l. It has a low tendency to adsorb to organic matter and soils and has a half-life in water of less than a month[3].
MCPP has a low potential to bioaccumulate and is therefore not likely to biomagnify[3].
Mecoprop causes acute toxicity in oysters at concentrations above 4 mg/l. Most fish species survive short exposure to concentrations of 10 mg/l and some even concentrations up to 500 mg/l[4].
