Effect of agricultural activity on levels of organochlorine pesticides in hard corals, fish and molluscs from the Great Barrier Reef

摘要: Abstract An organochlorine baseline study of selected corals, fish and molluscs has established that lindane is the only consistently detectable persistent pesticide in Great Barrier Reef organisms sampled. Samples taken during 1976–1977 from twenty reefs between Heron Island Lizard provide evidence distribution contamination related to agricultural usage coastal sugar cane growing regions. Consideration given possible mode transport reef environment. No polychlorinated biphenyls were detected any samples scattered contained levels residues other than lindane. Inner marginal shelf may be most pristine environment yet reported for pollutants.
