场地重金属污染与风险评价方法研究进展

Research progress on heavy metal pollution and risk assessment methods for sites

大量的污染场地给居民身体健康和生态环境带来了不可估量的损害,为提高健康水平以及生存环境质量,需科学地对污染场地进行污染风险分析及评价,进而制定有效的治理方案。从人为角度对当前场地污染来源进行了梳理,并针对生态风险评价和健康风险评价方法进行了分析。结合当前更为丰富的数据采集手段和大数据分析技术,提出了在污染大数据支持下的场地污染空间量化评价方法,为后续的场地污染治理提供技术支持。

A lot of polluted sites have brought immeasurable damage to people’s health and the ecological environment.In order to improve the health level and the quality of the living environment,it is necessary to conduct scientific pollution risk analysis and evaluation of polluted sites,and then formulate effective treatment plans.The current sources of site pollution from the perspective of human factors were sorted out.In response to these pollution,an analysis of current risk assessment methods from the perspectives of ecological risk assessment and human health risk assessment was conducted.Combining the current richer data collection methods and big data analysis technology,a quantitative assessment method of site pollution space supported by pollution big data was proposed,which provided technical support for subsequent site pollution control.
