Definition of mecoprop (MCPP):
Mecoprop has been used as a herbicide since 1960. It is an odourless, white to light brown crystalline solid 
This is the common definition for mecoprop (MCPP), other definitions can be discussed in the article
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.
In water it 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.
MCPP has a low potential to bioaccumulate and is therefore not likely to biomagnify.
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 survive short exposure to concentrations up to 500 mg/l.
