摘要
目的了解2017—2018年柳州地区市售包装饮用水中挥发性卤代烃污染情况,为柳州市包装饮用水安全性评估及相关污染防控提供科学数据。方法收集2017—2018年柳州市及地区共49个品牌160份市售包装饮用水,采用吹扫捕集-气相色谱法测定柳州地区市售包装饮用水中19种挥发性卤代烃含量。结果 160份包装饮用水中共检出二氯甲烷、三氯甲烷、四氯化碳、反1,2二氯乙烯、一溴二氯甲烷、二溴一氯甲烷、1,2-二氯乙烷、三溴甲烷8种挥发性卤代烃,有62份水样至少检出以上挥发性卤代烃中的一种,检出率为38.75%,有1份水中的三氯甲烷含量超标,超标率为0.62%。结论柳州市及地区市售包装饮用水挥发性卤代烃检出率较高,长期饮用对健康危害值得重视,应加强对包装饮用水中挥发性卤代烃的监测。
[Objective]To investigate the pollution status of volatile halohydrocarbons in packaged drinking water in Liuzhou region form 2017-2018,and to provide scientific data for the safety assessment of packaged drinking water and related pollution control.[Methods]From 2017-2018,160 packaged drinking waters from 49 brands were collected from the markets in Liuzhou Region,the contents of 19 volatile halohydrocarbons in packaged drinking waters were detected by the method of Purge and trap-gas chromatography.[Results]8 volatile halohydrocarbons were detected in water samples,included Dichloromethane,Trichloromethane,Carbon tetrachloride,trans-1,2-Dichloroethylene,Monobromodichloromethane,Dibromochloromethane,1,2-Dichloroethane and Tribromomethane.At least one of the above volatile halogenated hydrocarbons was detected in 62 water samples,and the detection ratio was 38.75%.One water sample with excessive trichloromethane content,and the exceeding rate was 0.62%.[Conclusion]The detection ratio of volatile halohydrocarbons in packaged drinking water in Liuzhou region is high.We should pay more attention to the impact of the long-term drinking to people’s health,and strengthen the monitoring of volatile halohydrocarbons in packaged drinking water.
