| Abstract |
Remote air monitoring using 0.45-micrometer Millipore filters at eight remote sites in the Great Smoky Mountains National Park has shown that lead particulates are contributing to the contamination of this designated biosphere reserve. Analytical results of these filters by atomic absorption spectrophotometry, x-ray fluorescence, and scanning electron microscopy showed that lead air concentrations varied frm a high of 141.ng/cu m to a low of 18.9 ng/cu m. The spherical shape of the lead particulates indicates that the moieties were formed by high temperature processes, such as by internal combustion engines. Also, the small particulate size may indicate long range transport and subsequent deposition from urban and/or industrialized areas. |
