摘要

In the United States, the Clean Air Act of 1970 (1) gave the U.S. Environmental Protection Agency (EPA) responsibility for ensuring clean air by monitoring six analytes routinely in ambient air, including SOx, NOx, PM10 (particulates < 10 μ), Pb, CO and ozone. In 1990, amendments to the Clean Air Act, expanded the measurements to include fifty four (54) volatile organic compounds (VOCs) that are precursors to the formation of ground-level ozone, implemented through a program known as Photochemical Assessment Monitoring Stations (PAMS). In 2008 the National Ambient Air Quality Standards (NAAQS) for ground-level ozone was reduced to 0.075 ppm for an 8-hour period. An ozone precursor list was also established in Europe, following the 1992 Ozone Directive and United Nations Eco-nomic Commission for Europe's protocol on controlling VOC emissions.
