退役化工企业污染场地健康风险评估(即第三阶段场地环境调查)

BACK A SERVICE CHEMICAL ENGINEERING BUSINESS ENTERPRISE POLLUTION PLACE HEALTHY RISK VALUATION(NAMELY THREE STAGE PLACE ENVIRONMENT SURVEY)

由于城市人口的急剧增长和工业经济的迅猛发展,固体废物不断向土壤表面堆放和倾倒,有害废水不断向土壤渗透,大气中的有害气体及颗粒物也不断随雨水降落在土壤中,导致了土壤污染。随着经济的发展和城市化建设进度的加快,场地性质的变更越来越频繁,位于城市中心地带或者工商业聚集区中的污染地块被改变用途后的潜在土壤污染风险问题已逐渐显现。污染场地健康风险评估考虑到多种污染物可能同时存在于场地不同的介质之中,如土壤、空气、水、食物和尘埃等,通过分析与受体相关的多种暴露途径,实现对多介质的健康风险评估,以可接受健康风险水平为出发点,提出保护人体健康的土壤修复目标值,风险评估结果是进行污染修复和管理决策的科学依据。

Because population in the city sharply increases and the fast fierce development of industry economy,the solid discard continuously piles to the soil surface and dumps,the harmful waste water continuously permeates to the soil,and the harmful air in the atmosphere and grain thing also continuously land with the rain water in the soil and caused soil＇s polluting.Because development and urbanization of economy constuct speeding of progress, the alteration of place property is more and more multifarious, be located in the gathering pollution ground within area of district in the city center or industry and business industry the piece be changed a latent soil in use pollution risk problem have already presented gradually.Pollute healthy risk valuation of place in consideration of various pollutants may be existed to a place to differently lie quality at the same time in, like soil, air, water, food and dust etc.,pass analysis and be subjected to various related revelation of the body path, carry out to the healthy risk valuation that lies more quality, take canning accept healthy risk level as a starting point, put forward the soil of protecting human body health repair target value, the risk analyzing result is science that carries on polluting repair and management decision basis.
