化学品环境暴露评估模型研究进展

各国政府高度重视化学品生产使用引发的环境问题,研发了一系列环境暴露预测模型,包含了点源暴露到面源暴露各种排放模式,局部暴露、区域暴露及洲际暴露的各种预测尺度,筛选评估到确认水平的不同评估层级,用于评估化学品的潜在风险。本文从模型功能、机理出发,综述了化学品环境暴露评估涉及的排放估计、水/土/气、多介质以及食物链评估模型,以期为推动我国化学品环境暴露模型的研发提供参考。     

Review on remediation technologies for arsenic-contaminated soil

• Recent progress of As-contaminated soil remediation technologies is presented. • Phytoextraction and chemical immobilization are the most widely used methods. • Novel remediation technologies for As-contaminated soil are still urgently needed. • Methods for evaluating soil remediation efficiency are lacking. • Future research directions for As-contaminated soil remediation are proposed. Arsenic (As) is a top human carcinogen widely distributed in the environment. As-contaminated soil exists worldwide and poses a threat on human health through water/food consumption, inhalation, or skin contact. More than 200 million people are exposed to excessive As concentration through direct or indirect exposure to contaminated soil. Therefore, affordable and efficient technologies that control risks caused by excess As in soil must be developed. The presently available methods can be classified as chemical, physical, and biological. Combined utilization of multiple technologies is also common to improve remediation efficiency. This review presents the research progress on different remediation technologies for As-contaminated soil. For chemical methods, common soil washing or immobilization agents were summarized. Physical technologies were mainly discussed from the field scale. Phytoextraction, the most widely used technology for As-contaminated soil in China, was the main focus for bioremediation. Method development for evaluating soil remediation efficiency was also summarized. Further research directions were proposed based on literature analysis.
