| 摘要: |
| 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7.6~152 ng/L，平均浓度为41 ng/L；该海域14种生物体中双酚A浓度介于ND~13.6 μg/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。 |

| Abstract: |
| 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 seawater 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 Neverita 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 respectively. In general, Laizhou Bay is already polluted by BPA, which may potentially bring about ecological problems. |
