Description
Summary:Assessment of contamination by polychlorinated biphenyls (PCBs) and aliphatic and aromatic hydrocarbons in sediments of the Santos and Sao Vicente Estuary System, Sao Paulo, Brazil is presented. In general, the distribution pattern of n-alkanes found in the Santos and Sao Vicente Estuary System shows an input of biogenic hydrocarbons from tropical forests and mangroves but the total aliphatic hydrocarbon concentration values are indicative of petroleum-contaminated area. The sediments of the Santos and Sao Vicente Estuary System show a large predominance of polycyclic aromatic hydrocarbons (PAHs) originating from combustion of coal in metallurgical processes, crude oil and diesel fuel from refineries, shipping and road haulage, and biomass burning resulting from the settlement of the population in the vicinities of the estuary.
