The integrated use of chemical analysis, cytochrome P450 and stress proteins in mussels to assess pollution along the Galician coast (NW Spain)

摘要

Aliphatic and polycyclic aromatic hydrocarbons (PAHs) as well as biochemical markers, such as cytochrome P450, benzo(a)- pyrene hydroxylase (BPH) and stress-70 proteins, were determined in mussels (Mytilus galloprovincialis) collected in October 1995 from several locations along the Galician coast (NW Spain). The survey proved the existence of a pollution gradient among sam- pling sites and a chronic exposure to petrogenic and pyrolitic hydrocarbons.
