Definition of Pentachloroanisole PCA:
Pentachloroanisole is a chlorinated aromatic compound, which is widely distributed 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 is easily evaporated and has a relative stability in the atmosphere, as such it is subject to long range environmental transport and can be found in remote areas such as the Arctic.

It appears 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 no 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].
