我国典型城市冬季龙头水中卤代酚类嗅味污染特征

Characteristics of Odorous Halogenated Phenols in Tap Water of Typical Cities in China in Winter

  • 摘要: 为研究我国典型城市冬季龙头水中卤代酚类嗅味暴露特征,以8种典型卤代酚类嗅味物质为研究对象,采用固相微萃取预处理,结合气相色谱-质谱联用仪对全国22个典型城市龙头水中的卤代酚类嗅味污染物进行定性、定量分析. 结果表明:在我国冬季典型城市龙头水中普遍存在卤代酚类嗅味物质暴露问题. 其中,以4-氯酚的暴露浓度最大,ρ(4-氯酚)最高为3 526.24 ng/L,ρ(2-氯酚)和ρ(2-溴酚)较小,最大暴露值均小于100 ng/L;ρ(2,6-二溴酚)与ρ(2,6-二氯酚)在各典型城市普遍出现超嗅阈值现象;就调查的城市而言,东北地区污染最为严重,其次为华北地区,中南和西部地区嗅味物质污染及超嗅阈值现象相对较轻.
