    Abstract
    An ecotoxicological study were conducted to evaluate the concentrations of PAHs and n-alkanes, in gut, liver and kidney tissues of two individuals of Enhydrina schistose (Daudin, 1803), using gas chromatography/mass spectrometry. The concentrations of PAHs (0.10 Mu g/g) and n-alkanes (8.12 Mu g/g) were elevated in the gut, and liver (PAHs 0.05 Mu g/g tissue, n-alkanes 29.16 Mu g/g tissue). In kidney of both specimen-A and B the PAHs (0.01 and 0.1 Mu g/g) and n-alkanes (0.22 and 2.06 Mu g/g) concentration was detected. This was an initial survey (n = 2) and the main goal was to know accumulation and distribution of PAHs and n-alkanes in the sea snakes. This study indicates high accumulation of petroleum hydrocarbon in gut, liver and kidney of sea snake. Since, this species also act as pray for sea eagles and some predatory fishes such as tiger shark, there is high possibilities of PAHs being circulated in marine food chain
