Production of PCP in the EU ceased in 1992. In 1996, 378 tonnes of NaPCP and 30 tonnes of PCP were imported from the USA, there may possibly be other imports from Asia. NaPCP was mainly used in France, Portugal and Spain, as a control agent to protect newly cut wood surfaces against fungal attacks. Treatment of wood and textiles resulted in release of PCP to the environment. Since 2008 no products which contain more than 0,1% of PCP are allowed to be sold.
Due to it's low water solubility, PCP in the the marine environment will adsorb to sediments, where it is quite stable. In water it can be degraded by photolysis. PCP has a tendency to bioaccumulate and biomagnify through food chains. It also is considered toxic for marine organisms. In humans it can cause liver damage and have endocrine disrupting effects.
Its main degradation product is pentachloroanisole.
