摘　　要：测定了桂林地区水系沉积物中酸可挥发硫 (AVS)与同步提取的重金属 (SEM) ,研究了桂林地区水系沉积物中酸可挥发硫随深度的变化特征 ,并用 [SEM] [AVS]方法对桂林地区水系沉积物中重金属的生物毒性进行了初步预测。It was measured that the acid volatile sulfide (AVS) and simultaneously extracted metals (SEM) in aquatic sediments of Guilin, and the character of AVS changing with depth was also studied.A preliminary prediction of biological toxicity of the heavy metals to aquatic sediments of Guilin was conducted by means of [SEM]/[AVS].
