DISTRIBUTION OF PETROLEUM HYDROCARBON CONCENTRATIONS IN COASTAL SEDIMENTS ALONG TAMILNADU COAST, INDIA

Full text

Abstract: The distribution of petroleum hydrocarbons along the coastal surface sediments of six stations between Pondicherry and Nagapattinam, Bay of Bengal, India were made during 2008. The Petroleum Hydrocarbon Concentrations (PHc) were in the range 1.48 to 4.23 ppm. The PHc in Bay of Bengal is comparatively lower than in the Arabian Sea. The petroleum hydrocarbon concentrations are high in clay rich sediments than sand. The study revealed that the PHc values of Tamilnadu coastal sediments are much lower than the values reported from selected costal areas including the sediment of the Indian coast.
