南充29条河流水中溴化物和溴酸盐的分布特征

Distribution Characteristics of Bromide and Bromate in River Water of Nanchong City

采用离子色谱法分析了南充市境内8个饮用水源地水源水和29条河河水中溴化物和溴酸盐的含量,了解了南充市内水体中溴化物和溴酸盐的地区分布特征。结果表明:8个饮用水源水和29条河河水中均检出有溴化物,其中高坪区含量最高,平均浓度为22.9μg/L,西充县溴化物含量最低,平均浓度为3.64μg/L。8个饮用水源水均未检出溴酸盐,29条河有6条河水中检出溴酸盐的存在,表明该6条河流受到了溴酸盐的污染,河中溴酸盐的污染势必会对这些地区的水生生态系统和人类健康产生潜在的负面影响。

The content of bromide and bromate in 8 drinking water sources and 29 rivers in Nanchong City was analyzed by ion chromatography,and the regional distribution characteristics of bromide and bromate in water bodies in Nanchong City were understood.The results showed that bromide was detected in 8 drinking water sources and 29 rivers.Gaoping District had the highest bromide content with an average concentration of 22.9μg/L,while Xichong County had the lowest bromide content with an average concentration of 3.64μg/L.No bromate was detected in 8 drinking water sources,and bromate was detected in 6 out of 29 rivers,indicating that the 6 rivers were polluted by bromate.The bromate pollution in the rivers is bound to have a potential negative impact on the aquatic ecosystem and human health in these areas.
