瑞士空气污染管制法及PM10和PM2．5的限排措施

瑞士的环境质量在世界上堪称一流，这得益于瑞士严格执行政府1985年出台的《空气污染管制条例》，在控制PM10和PM2．5排放方面，要求明确，措施得当。瑞士PM10和PM2．5的最大排放源分别为农林和居住与商业。瑞士在道路交通、铁路、水运和航空运输、施工机械与设备、燃烧、工业设备与生产流程以及农业等领域均采取了一系列的减排措施，如，规定柴油的含硫量不得超过10mg／kg，各种车辆须加装可以过滤包括PM2．5的新型高效尾气排放过滤器等等。瑞士的经验表明，有效控制PM10和PM2．5的排放量，一是要细化规章制度，二是要有必要的技术手段。

Air Pollution Control Act of Switzerland and Its Limit Emission Measures for PM 10 and PM2.5

Based on the Air Pollution Control Act of Switzerland released in 1985 and reports on the air quality from Federal Environmental Protection Administration, this article introduces emissions of PM 10 and PM2.5 in Switzerland and the related emission control measures taken by the government. The paper lists the 4 main emission sources of PM 10 and PM2.5, i.e., emissions from agriculture, forestry, living and business activities, the existing data of PM 10 and PM2.5 emissions in 2005 and 2010, as well as the predicted emissions data for 2020. Switzerland is committed to take measures to control PM 10 and PM2.5 emissions from transportation systems, construction machinery, and industrial combustion equipments and operations, etc. For example, the sulfur in diesel exceeding 10 mg/kg is not allowed for use; all kinds of vehicles need to be equipped with efficient filters that can reduce exhaust including PM2.5. The experience of Switzerland shows that detailed regulations and advanced technologies are crucial for efficient control of PM 2.5 and PM 10 emissions.
