通过物质流分析方法展示某种元素进出某区域/企业的流动模式，从而评估元素在产品生命周期的某一阶段对工艺、产品和环境产生的潜在影响。介绍了物质流分析方法的研究现状及进展，重点提出重金属元素物质流分析应用方法与步骤，并根据数量、环境、资源经济和影响能力等指标，定量分析和评估重金属元素在生产过程中对工艺、产品和环境产生的影响及结果。以砷元素为研究对象，通过2家涉砷企业的案例，分析生产过程中砷元素的分布、贮存与走向，在此基础上明确了砷污染控制的关键环节和防控方向，为企业实现重金属总量削减、环境改善及清洁生产目标提供依据。

Substance Flow Analysis ( SFA) is used to show the flow pattern of an elementary substance as it enters and leaves a region or factory , which can be used to evaluate the impacts of the element on the production processes , products and environment during various processes in product life cycle .The progress and status of SFA methods were comprehensively reviewed , and the methods and procedure for analysis of heavy metals established . The main factors influencing the production processes , products and environment , such as the amount of heavy metal, environmental and economic indicators , were quantitatively analyzed and evaluated .Specifically, focusing on arsenic and with case studies in two enterprises , the distribution , occurrence and tendency of arsenic during the production process were analyzed .On this base , the key links and directions for arsenic control were identified , thus providing guidance for enterprises to realize total amount reduction of heavy metals , improve the environment and cleaner production .
