Assessing contamination from maritime trade and transportation on Iberian waters: Impact on Mytilus sp

Contamination derived from maritime transportation is not only linked to petroleum-based substances but also of other such as hazardous and noxious nature (HNS). Over the last decade, trade HNS has been augmenting. However, levels in aquatic environment are still quite unknown. So, an integrative study, combining a chemical multi-biomarker evaluation, was done NW Atlantic Iberian coast where specimens Mytilus sp. were collected. Ten found digestive gland mussels Vila Chã Foz, though at generally low levels. Only measurable benzene, trichloroethylene 1,1,2-trichlorethane locations. Principal component analysis produced clear distinction between Foz remaining sampling sites. Biomarkers associated contamination lipid peroxidation (LPO) activity glutathione reductase (GR), superoxide dismutase (SOD) peroxidase (GPx) enzymes. Correlations biomarkers highlight importance performing biomonitoring campaigns integrating biomarker approach accurately assess environmental state environments.
