对浏阳市境内浏阳河水、底泥及附近土壤中高氯酸盐的污染水平进行了研究,结果发现所采集的浏阳河水中均含有较高浓度(65.8—170.0μg.l-1)的高氯酸盐,并且其含量与距离浏阳市的远近有很大相关性;但底泥样品中基本不含高氯酸盐,土壤样品中高氯酸盐含量也相对较低(0.68—14.1μg.kg-1),这从一定程度上说明了高氯酸盐在固体介质中具有较弱的吸附,并且一旦进入水环境介质中即会随着地下水或地表水快速扩散.
In this paper,perchlorate in river water,sediment and its nearby soil was detected for investigating the perchlorate pollution level in Liuyang river.The result showed that high concentration perchlorate was detected in river water and it was in the range of 65.8—170.0μg·l-1.And the concentration of perchlorate in river water has a significant correlation with the distance between sampling site and Liuyang city.The investigation also showed that no perchlorate was detected in the sediment and low level concentration of perchlorate(0.68 to 14.1μg·kg-1)exists in nearby soil.The result indicated that there is perchlorate pollution problem in Liuyang river.
