Occurrence and risk assessment of bisphenol A and alkylphenols as new pollutants in the Hubei section of the Yangtze River Basin

双酚A(Bisphenol A, BPA)和烷基酚(Alkylphenols, APs)是典型的具有内分泌干扰效应的新污染物, 对生态环境和人类健康构成潜在风险. 本研究针对长江流域湖北省内的主要地表水、饮用水水源和自来水, 系统开展了BPA和APs的污染筛查与风险评估. 结果显示, 地表水、饮用水水源和自来水中BPA和APs的总浓度范围(平均值)分别为ND~1818 ng/L(442 ng/L)、19.1~2974 ng/L(1236 ng/L)和ND~128 ng/L(38.7 ng/L). BPA是地表水(平均浓度: 411 ng/L)和水源地(平均浓度: 1186 ng/L)中最主要的酚类污染物, 而自来水中BPA的检出率较低(21%), 支链壬基酚(NP)是自来水中最主要的单体(平均浓度: 25.8 ng/L, 质量浓度占比67%). 丰水期与枯水期污染物浓度存在显著差异, 丰水期BPA浓度较高, 而枯水期支链APs浓度显著增加. 相关性分析表明, BPA和APs的浓度与pH值、总溶解固体和总氮等水质参数呈显著正相关, 与氧化还原电位呈显著负相关. 风险评估结果表明, 丰水期BPA对部分水源地的绿藻存在中等生态风险, NP对鱼类和水蚤的风险普遍高于枯水期; 武汉市区自来水中BPA和APs的总体健康风险较低, 未构成显著威胁. 本研究明确了长江流域湖北省内BPA和APs的污染特征及潜在风险, 为饮用水安全保障和生态风险防控提供了科学依据, 为区域环境新污染物治理提供了基础数据.

Abstract

双酚A(Bisphenol A, BPA)和烷基酚(Alkylphenols, APs)是典型的具有内分泌干扰效应的新污染物, 对生态环境和人类健康构成潜在风险. 本研究针对长江流域湖北省内的主要地表水、饮用水水源和自来水, 系统开展了BPA和APs的污染筛查与风险评估. 结果显示, 地表水、饮用水水源和自来水中BPA和APs的总浓度范围(平均值)分别为ND~1818 ng/L(442 ng/L)、19.1~2974 ng/L(1236 ng/L)和ND~128 ng/L(38.7 ng/L). BPA是地表水(平均浓度: 411 ng/L)和水源地(平均浓度: 1186 ng/L)中最主要的酚类污染物, 而自来水中BPA的检出率较低(21%), 支链壬基酚(NP)是自来水中最主要的单体(平均浓度: 25.8 ng/L, 质量浓度占比67%). 丰水期与枯水期污染物浓度存在显著差异, 丰水期BPA浓度较高, 而枯水期支链APs浓度显著增加. 相关性分析表明, BPA和APs的浓度与pH值、总溶解固体和总氮等水质参数呈显著正相关, 与氧化还原电位呈显著负相关. 风险评估结果表明, 丰水期BPA对部分水源地的绿藻存在中等生态风险, NP对鱼类和水蚤的风险普遍高于枯水期; 武汉市区自来水中BPA和APs的总体健康风险较低, 未构成显著威胁. 本研究明确了长江流域湖北省内BPA和APs的污染特征及潜在风险, 为饮用水安全保障和生态风险防控提供了科学依据, 为区域环境新污染物治理提供了基础数据.
