Description
Summary:The concentrations of eight polycyclic aromatic hydrocarbons (PAH) in the clam Tridacna maxima were measured as indicators of hydrocarbon pollution in the Great Barrier Reef, Australia. At most sampling locations, pah were not significantly above limits of detection; pyrene and chrysene concentrations were both less than 0.07 mg/kg, and benzo-a-pyrene levels were less than 0.01 mg/kg. These pah levels appear to be the lowest reported for clams in the world, reflecting the pristine nature of the reef. Low levels of contamination were observed at two sites, attributable to pollution from power boats.
