Definition of Pentachloroanisole PCA:
Pentachloroanisole is a chlorinated aromatic compound which is widelydistributed at low levels in the environment. It is the main degradation product of pentachlorophenol (PCP) and pentachloronitrobenzene. [1]
This is the common definition for Pentachloroanisole PCA, other definitions can be discussed in the article

Notes

Pentachloroanisole
Pentachlorophenol
Formula
C7H3Cl5O

As pentachloroanisole has a relative stability in the atmosphere and is easily evaporated, it is subject to long range environmental transport. It can therefore also be found in remote areas such as the Arctic. It appear to be quite stable in the environment and have a very high (higher than PCP) potential to bioaccumulate. Evidence for biomagnification still has to be produced. There is not information available on its toxicity. However, in biota PCA can be demethylated back to PCP, which is more easily excreted. Therefore PCA can have a similar toxicity. [1]
