对葫芦岛连山湾海洋沉积物进行了实验室研究。通过模拟实验研究了Cl-、SO 42-和HCO 3 - 3种阴离子对沉积物中Cd、Pb、Cu和Zn释放的影响。结果表明，3种阴离子对土壤的影响顺序为Cl−> HCO 3 −> SO 42-。各阴离子对重金属的释放潜力顺序为：Cd> Cu>Zn> Pb。Cl −含量与Cd释放量呈正相关，与Cu、Zn释放量无显著相关性。对于SO 42-和HCO 3-，海洋沉积物中重金属的释放不明显。
Marine sediments from Lianshan Bay in Huludao, China, were studied in laboratory. A series of simulated experiments were carried out to investigate the influences of three kinds of anions Cl−, SO42-and HCO3−on the release of Cd, Pb, Cu and Zn from the sediments. The results showed that the sequences about the impact of the three anions were Cl−>HCO3−>SO42-. The release potential of heavy metals in the presence of each anions was in the following order: Cd≫Cu>Zn≈Pb. The correlations were positive between Cl−content and the quantity of Cd released from the marine sediment, whereas there was no significant relationship between Cl−content and amount of Cu and Zn released. For SO42-and HCO3−, the release of the heavy metals from marine sediments was not obvious.
