The concentration and distribution of bisphenol A, tetrabromobisphenol A and three kinds of alkylphenols in surface water and sediments from Taihu Lake and its tributaries were investigated by solid phase extraction and high liquid chromatography-electrospray tandem mass spectrometry (SPE-HPLC-MS/MS). The results showed that NP and BPA were the main Contaminants with an average content of 29.6ng/L (0~121ng/L) and 17.5ng/L (0~55.1ng/L) in surface water, respectively. The average concentration of NP in sediment was 240ng/g (0~2045ng/g), followed by TBBPA, with an average of 81.0ng/g (0~901ng/g). The correlation analysis showed that the total of the targets was positively correlated with the TOC in sediments. Overall, the pollution of its tributary and North Taihu Lake were more serious. In addition, the ecological risk assessment results showed that the entropy risk entropy of the targets in Taihu Lake and its tributaries was relatively high, and its ecological risk can't be ignored. However, the risk assessment for human health showed that the EEQt <1ng E2/L, which does not have a significant risk.%采用固相萃取-高效液相色谱/串联质谱法(SPE-HPLC-MS/MS)对太湖及支流表层水和沉积物中双酚A(BPA)、四溴双酚A(TBBPA)和3种烷基酚类化合物的浓度水平及分布特征进行调查,并对其潜在风险进行评估.结果表明,表层水体中壬基酚(NP)和BPA是主要检出组分,平均含量分别为29.6ng/L(0~121ng/L)和17.5ng/L(0~55.1ng/L);沉积物中 NP 的浓度含量最高,平均值为240ng/g(0~2045ng/g),其次为TBBPA,平均值为81.0ng/g(0~901ng/g),且目标物总含量与沉积物中TOC含量具有正相关性,整体污染趋势表现为太湖支流和北太湖较严重.生态风险评价结果表明,太湖及其支流水体中目标物的联合毒性风险熵相对较高,其生态风险不容忽视;另外,5种目标物对于人体健康风险评估表明,健康风险总EEQt值<1ng E2/L,对于人体健康不具有明显的风险.
