Histopathology and bioaccumulation of metals, polycyclic aromatic hydrocarbons and linear alkylbenzene compounds in mussels transplanted along Ṣo Paulo coast РBrazil

The mussels transplanted to São Sebastião Channel showed bioaccumulation of Cr, Zn, Hg and polycyclic aromatic hydrocarbons (PAH), whereas organisms transplanted to Santos bay showed increased concentrations of Cr, Zn, Pb, PAH, and linear alkylbenzenes. The gills exhibited histological alterations such as fusions of filaments, hypertrophies of mucous cells and parasite infections. This integrated approach for mussels kept under field conditions could be considered a useful tool for marine environmental assessments providing a better comprehension of the bioavailability and effects of contaminants in coastal zones.
