| 摘 要： | 以食用菲律宾蛤仔为研究对象,采用半静态动力学富集实验方法,探讨双壳贝类对石油烃的污染动力学特征。结果表明:经过4d石油烃在贝体和水环境之间达到稳态平衡;生物富集系数(BCF)为545;浓度为0.068 mg/L的石油烃水体组,富集平衡后贝体内的石油烃含量高于贝体内的石油烃异味阈值(25~30mg/kg)。参考USEPA、GB18421-2001等关于双壳贝类中石油烃限量的规定,根据石油多环芳烃的毒力机理,把菲律宾蛤仔对石油烃污染的安全阈值定为0.03~0.05mg/L较为合理。

| Abstract: | The petroleum hydrocarbon pollutants accumulated by bivalve mollusks present risk to human consumer.The bioconcentration of petroleum hydrocarbons by Ruditapes philippinarum was examined by using the semi-static kinetic experiment.The results of the bioconcentration showed that the petroleum hydrocarbon pollutants reached balance between shellfish and water enviroment after 4 days of experiment and the average bioconcentration factor(BCF) was 545 with the maximum accumulation content being higher than the threshold of odours or flavours(25~30mg/kg) at 0.068 mg/L in water.According to the safety level in shellfish from USEPA and GB18421-2001,as well as the metabolism of PAHs,the safety level of petroleum hydrocarbons for Ruditapes philippinarum was considered as 0.03~0.05mg/L. |
