摘要
总结了沉积物中重金属诱发释放的影响因子,包括:沉积物所处的水环境化学条件、水流紊动强度及国内外学者关于沉积物中重金属诱发释放的最新研究得出的影响因子。通过对这一系列影响因子诱发释放作用规律的归纳,从而为解决沉积物中重金属释放的二次污染问题提供理论依据;对于水生生态系统的维护、饮用水的安全供给具有重要意义。
Ingredients on release of heavy metals from sediment, mainly including： the chemical condition of water environment where sediment was located were summarized, including intensity of stream turbulence and the influencing ingredients on release of heavy metals newly studied by domestic and overseas researchers. By concluding this series of regulations of the influencing ingredients on eliciting release, the principle foundation of solving the secondary-pollution caused by release of heavy metals from sediment was it supported; which also embodied prolong signifieanees of maintaining water ecosystem and safely supplying drinking water.
