摘要: 采用固相微萃取、气-质联用方法,调查了珠江口地区鱼塘、河流及入海口表层水中双酚A(BPA)的污染特征,分析了BPA残留水平与环境因子的关系。结果显示:珠江口地区鱼塘、横门水道、入海口表层水中BPA均值分别为1.19、1.41和2.06μg·L-1。相关分析表明水体中BPA残留量与pH值显著相关(P<0.05)。根据EC/PNEC(环境中某一污染物的残留水平与该污染物生态风险阈值之比)指标判断,目前珠江口地区表层水中BPA残留水平不会产生生态风险。

Abstract: Content levels of bisphenol A(BPA)in the surface waters of the Pearl River Estuary,Hengmen river and fishponds were determined by means of solid phase microextraction(SPME)and gas chromatography-mass spectra(GC-MS).Results show that the content of BPA in the three waters was 1.19,1.41 and 2.06 μg·L-1,respectively.A significant relationship was observed between the contents of BPA and pH.According to the EC/PNEC evaluation system,the residual extent of BPA in the Pearl River Estuary area might not bring about any significant ecological risk to the environment and human beings.

Key words: bisphenol A, surface water, Pearl River Estuary, environmental factor
