莱州湾海域双酚A污染现状调查

Survey of bisphenol A contamination in Laizhou Bay

本研究采用气相色谱-质谱法对莱州湾海域表层海水和生物体中双酚A含量进行调查监测。结果显示,莱州湾29个站位表层海水均有双酚A检出,浓度为7.6～152ng/L,平均浓度为41ng/L;该海域14种生物体中双酚A浓度介于ND～13.6μg/kg之间;扁玉螺、脊腹褐虾和青鳞小沙丁鱼对双酚A的浓缩系数(BCF)较高,分别为137、133和124,鲬和银鲳较低,分别为40.1和45.6。莱州湾海域已经遭受双酚A污染,存在潜在的生态安全问题。

Bisphenol A （BPA） in surface seawater and marine organisms in Laizhou Bay was analyzed by GC-MS in our research. The results showed that BPA was detected in the sea- water of all the 29 sites and the concentrations ranged between 7.6-152ng/L, with the average concentration of 41ng/L. BPA concentrations in marine organism ranged between ND 13.6μg/kg. Bioconcentration factor （BCF） of BPA varied in different organisms. BCFs of Nev- erita didyma, Crangon affinis and Sardinella zunasi were 137, 133 and 124 respectively, higher than that of Platycephalus indicus and Pampus argenteus, which were 40.1, 45.6 re- spectively. In general, Laizhou Bay is already polluted by BPA, which may potentially bring a bout ecological problems.
