摘　　要：南通如东滩涂是文蛤(Meretrix meretrix)的重要产地,本研究于2010年3、5、8和11月对该地区文蛤生长环境及体内的石油烃(TPHs)含量与分布进行了调查。研究表明:表层海水中各季均出现油类轻度污染站位,其中夏秋2季的油类污染程度略高于冬春;虽然4季沉积物中油类含量均符合《海洋沉积物质量》Ⅰ类标准,但沉积物中油类含量的季节变化显著,最高值出现在夏季,这可能与该时间段内的潮流冲刷等因素导致的沉积物机械组成不同有关;文蛤体内TPHs平均含量的季节分布为春季>夏季>冬季>秋季。文蛤体内TPHs含量易受沉积物和水体中油类含量的影响。Rudong tidal flat is an important production area of clam（Meretrix meretrix）.In order to understand the pollution status of petroleum hydrocarbon in the calm habitat of the tidal flat,an investigation was conducted on the total petroleum hydrocarbon（TPHs） concentration in the clam body and its growth environment in March,May,August,and November 2010.In the surface sea water,there were several observation sites appeared slight oil pollution in each season,and the pollution degree was slightly higher in summer and autumn than in winter and spring.Though the sediment TPHs concentration in four seasons conformed to the first degree of the national standard ＂Marine Sediment Quality＂,it had an obvious seasonal variation,being the highest in summer,possibly due to the changes of sediment mechanical components caused by tide flush.The mean concentration of TPHs in the clam body was the highest in spring,followed by in summer,winter,and autumn.It was suggested that the TPHs concentration in the clam body was susceptible to the oil content in the sediment and water body.
