The present study reports the level of total petroleum hydrocarbon (TPH) in 27 commercially important fish, crustaceans and cephalopods from Orissa coast, Bay of Bengal to provide the baseline data for oil contamination in marine biota. The results showed significant differences in the TPH concentration in different species. Of all fish, Carangoides malabaricus showed the maximum TPH level (av. 13.70 μg g(-1)). In cephalopods, Loligo recorded the maximum TPH (av. 14.87 μg g(-1)) while Metapenaeus dobsoni recorded the maximum TPH (av. 13.18 μg g(-1)) among crustaceans. The concentration of TPH recorded in the present study were higher than the reported values from other studies in Bay of Bengal but were comparable with those of other Indian coast and Gulf water. The species recording maximum concentration and giving significant correlation coefficient may be of interest in oil pollution monitoring and can be used as indicator of hydrocarbon pollution in the region.
本研究报告了孟加拉湾奥里萨邦沿海 27 种商业上重要的鱼类、甲壳类和头足类动物中的总石油烃 (TPH) 水平，为海洋生物中石油污染提供了基线数据。结果表明，不同物种的 TPH 浓度存在显著差异。在所有鱼类中，马拉巴尔鲹（Carangoides malabaricus）的 TPH 水平最高（平均 13.70μg/g）。在头足类动物中，乌贼（Loligo）的 TPH 最高（平均 14.87μg/g），而短尾大眼蟹（Metapenaeus dobsoni）的 TPH 最高（平均 13.18μg/g）。本研究中记录的 TPH 浓度高于孟加拉湾其他研究报告的值，但与其他印度沿海和墨西哥湾水域的值相当。记录最高浓度并给出显著相关系数的物种可能对石油污染监测感兴趣，可以用作该地区碳氢化合物污染的指标。
