| 中文摘要 |
| 本研究进行了乐安江沉积物不同溶解氧浓度条件下的重金属释放实验和沉积物样品酸可挥发硫化物(AVS)及同时可提取金属浓度(SEM)的测定。结果表明,乐安江沉积物中AVS含量较低,沉积物中重金属存在再释放的可能性,铁锰氧化物可能是乐安江沉积物结合重金属的主要成分。 |
| 英文摘要 |
| This research did aeration experiments and the measurementof acid-volat ile Sulf ide(AVS)and simult aneously extract ed metals(SEM)for a set of sedimentsamples in Le An River to determine the metal release potential. It was found that AVS in Le An River sediment is low and there would be the risk of second pollution in the way of mobilization of sediment bound metals tothe overly ing water. It is most likely that the iron and manganese oxide are important metal binding com ponents in Le An River sediment. |
