中文摘要:
      选取上海涉铝行业为研究对象,分析涉铝行业企业产排污环节,梳理现行铝污染排放限值或环境质量标准,计算基于人体健康风险的土壤铝筛选值。结果表明:目前中国针对铝污染排放尚无完善的标准和管理体系,现行污染控制标准已落后于当前涉铝行业规模发展水平,对土壤中的铝没有浓度限值要求。随着风险管控管理水平的发展,涉铝环境质量标准或污染排放标准体系亟待建立。结合案例区典型特征参数,考虑经口摄入表层土壤和呼吸吸入表层土壤颗粒物2个可能的暴露途径,推导土壤铝风险控制值。建议第一类用地筛选值参考该市“七五”背景值(6.65%)或调查区域背景值,第二类用地筛选值参考基于健康风险的土壤筛选值(12.5%)。旨在为今后污染行业企业周边相关土壤环境中铝的风险管控提供理论依据,为完善土壤污染生态风险评估技术体系提供技术支撑。土壤铝的迁移转化、生物可利用性及毒性与其化学形态也息息相关,建议加强不同铝形态的测定方法研究及相关管控标准的制定。
英文摘要:
      The aluminum-related industry in Shanghai was selected as the research object,the production and sewage discharge links of enterprises in the aluminum-related industry were analyzed, the current aluminum pollution emission limits or environmental quality standards were sorted out, and the soil aluminum screening value based on human health risks was calculated. The results showed that there is currently no perfect standard and management system for aluminum pollution discharge in China,and the current pollution control standard has lagged behind the current scale development level of China's aluminumrelated industry,and there is no concentration limit requirement for aluminum in soil. With the development of risk management and control management level,aluminum-related environmental quality standards or pollution emission standard systems need to be established urgently. Combined with the typical characteristic parameters of the case area,considering the two possible exposure pathways of oral ingestion of surface soil and respiratory inhalation of surface soil particulate matter,it is recommended that the first type of land use screening value refer to the background value of the 7th Five-Year Plan of the city (6. 65%) or the background value of the survey area,and the second type of land use screening value is based on the health risk soil screening value(12. 5%), aiming to provide a theoretical basis for the risk management and control of aluminum in the relevant soil environment around polluting industry enterprises in the future,and provide technical support for improving the technical system of soil pollution ecological risk assessment. The migration and transformation,bioavailability and toxicity of soil aluminum are also closely related to its chemical form,and it is recommended to strengthen the research on the determination methods of different aluminum forms and the formulation of relevant control standards.
