Unraveling the differences between pyrolytic and petrogenic sources in oiled areas of the South Atlantic: An analytical method for biliary PAHs.

Polycyclic aromatic hydrocarbons (PAHs) represent significant organic pollutants within the scope of environmental monitoring and management investigations of oiled areas. Characterized as precursors of mutagenic and carcinogenic processes, they exert a direct influence on human and environmental health. To assess the impacts of one of the largest oil spills affecting coral reefs in Alagoas, Brazil, researchers developed, validated, and applied an innovative methodology.
