TAILIEUCHUNG - Accumulation of heavy metals and poly aromatic hydrocarbons in marine fishes around offshore oil and gas fields in west coast of India

Accelerated exploitation of oil and gas resources planned and implemented by ONGC and BGEIPL in west coast offshore region would result into stress particularly on marine environment. The long term physical, chemical and biological changes due to routine discharges from offshore installations can best be assessed through a study on accumulation of hydrocarbons and heavy metals in fishes, plankton and sediments which together form biotic and abiotic components of marine environment. The accumulation of hydrocarbon and heavy metals are considered as major threat to biota when concentration levels exceed the levels of toxicity either in abiotic or biotic environment. The existing scenario is based on the data generated in the offshore area of west cost of India. Studies were carried out to find out the levels of hydrocarbons and heavy metals and their accumulation in marine fish tissues of liver, muscle, grills and reproductive organs in and around offshore oil and natural Gas field in west cost of India. Data was collected for post monsoon and pre-monsoon seasons. It was observed that levels of hydrocarbons in gills were found to be high (2128 µg/g) during pre-monsoon and might be the primary uptake site of hydrocarbons through water and the micellar layer in grills might be playing an important role in absorption/adsorption of hydrophobic hydrocarbons. However, hydrocarbons levels in the water column, during the study were observed in the range of ND – µg/l, presence of high levels of hydrocarbons in fish tissues, could be explained only through the process of both bioaccumulation and biomagnification. | Accumulation of heavy metals and poly aromatic hydrocarbons in marine fishes around offshore oil and gas fields in west coast of India
