(PDF) Analysis of heavy metals in atmospheric particulate

1.1 This test method describes the automatic separation and collection on chemically treated paper tapes of particulate and gaseous forms of acidic fluorides in the atmosphere by means of a double paper tape sampler. The sampler may be programmed to collect and store individual air samples obtained over time periods from several minutes to 3 h. A 30.5-m (100-ft) tape will allow unattended

National Ambient Air Quality Standards - Wikipedia

The U.S. National Ambient Air Quality Standards are limits on atmospheric concentration of six pollutants that cause smog, acid rain, and other health hazards. Established by the United States Environmental Protection Agency under authority of the Clean Air Act, NAAQS is applied for outdoor air throughout the country. The six criteria air pollutants, or criteria pollutants, for which limits are set in …
