摘　　要：用原子吸收分光光度法测定了桂林水系沉积物间隙水中的铜、铅、镉,用原子荧光法测定了间隙水中的汞和砷,以确定桂林水系毒性元素的污染情况.结果表明:污染最严重的是铜,平均值为0.097 3 mg/L,最大达0.236 1 mg/L;其次是铅、镉,平均值分别为0.088mg/L和2.200μg/L,最大值分别为0.244 5 mg/L和5.900μg/L;而汞和砷没有造成对间隙水的污染.污染最严重的水域是桃花江,漓江次之,青狮潭水库污染最轻.Copper, lead and cadmium in aquatic sediments of Guilin are analyzed by the method of atomic absorption spectroscopy analysis, arsenic and mercury by the method of atomic fluorescence spectroscopy analysis to determine the pollution degree of poisonous elements in interstitial water from sediments in Guilin. It is found out that the most harmful element is copper, with an average value of 0. 0973 mg/L, the maximum value being 0. 2361 mg/L. For lead and cadmium, their average values are 0. 0880 mg/L and 2. 200 μg/L, with maximum values of 0. 2445 mg/L and 5. 900 μg/L, respectively. Arsenic and mercury are not the causes for interstitial water pollution. Taohuajiang River is the most severely tainted while Qingshitan Reservoir is the least polluted. Lijiang River falls between Taohuajiang River and Qingshitan Reservoir.
