Pentachlorophenol
Definition of pentachlorophenol (PCP):
Pentachlorophenol is a white organic solid with needle-like crystals and a phenolic odor.[1] It is an organochlorine compound used mainly as a fungicide. Sodium pentachlorophenate and pentachlorophenyl laurate (PCPL), are used for similar purposes.[2]
This is the common definition for pentachlorophenol (PCP), other definitions can be discussed in the article

Notes
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 attack. 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 can be sold.
Typical concentrations of PCP in the North Sea are around 0,07 µg/l, with a maximum detected concentration of 0,79 µg/l. These concentrations have been decreasing since 1983. [2]
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 bioacumulate and biomagnify.[3] It also is considered toxic for marine organisms. In humans it can cause liver damage and have endocrine disrupting effects[4]
