【摘要】Bisphenol A (BPA) in surface water and sediments of aquiculture pond in Zhongshan City was determined. BPA is detected in all surface water samples and 44.4% sediment samples. Residual content of BPA in surface water is in the range of 0.96 ~ 4.51 μg · L~(-1), with an average of 3.29 μg · L~(-1), that in sediments is in the range of 0.19～1.31 ng · g~(-1)(dry weight), with an average of 0.23 ng·g~(-1) (dry weight). No significant relationship exists between BPA content and that of main environmental factors, except for pH and COD. Based on EC/PNEC evaluation standard, BPA residuary extent of the aquatic environment in Zhongshan City could induce minimal ecological risk to people and the environment.%对地处珠三角的中山市鱼塘表层水及底泥中双酚A(BPA)污染水平进行了测定分析,结果表明:鱼塘表层水样品中BPA检出率为100%,底泥样品中BPA检出率为44.4%.鱼塘表层水中BPA残留量为0.96～4.51μg·L~(-1),平均浓度为3.29μg·L~(-1);底泥中BPA含量较低,浓度范围为0.19～1.31 ng·g~(-1) (干重),平均浓度为0.23 ng·g~(-1) (干重).相关及回归分析表明,除pH及COD外,BPA残留量与大部分环境因子关系不密切.参照EC/PNEC体系,BPA在中山鱼塘水体中的残留水平不会导致生态风险. 【总页数】5页(1240-1244)
