Ecology and Management of a Forested Landscape

چکیده
While official PM,,, monitoring data for South Carolina are not available, unpublished data indicate that emissions at rural sites exceed the annual PM,., concentration standard of 15 pg/m3 from April to September each year. The possibility that PM,,, standards might be exceeded near the forest-urban interface could restrict burning in the future. In contrast, PM,, concentrations seldom approached half of the annual mean standard of 50 yg/m3 (table 3.3).
