Abstract

"The purpose of this investigation was to study the distribution of metallic particulates in the air surrounding the AMAX Lead Company of Missouri smelter in the "New Lead Belt" of southeast Missouri. The study included the evaluation of the temporal and spatial variation of dustfall and deposition rates of settleable particulate lead, zinc, copper, and cadmium, and transport and distribution of total suspended particulates and suspended particulate trace metals.

The study was conducted within a 3 x 3-mile grid around the smelter employing twenty dustfall stations and five HiVolurne samplers. The samples collected were analyzed for lead, zinc, copper and cadmium with atomic absorption spectroscopy.

The dustfall reached a highest value of 56 g/m2-mo in February but the maximum settleable particulate lead deposition rate of 239 mg/m2-mo occurred in December. The deposition rate of lead, zinc, copper, and cadmium was in the same decreasing order as found in the lead ore concentrate. The deposition rates of settleable dust and trace metals were found to decrease as the distance from the stack increased; this decrease followed a logarithmic law. This investigation also indicated that there is a potential danger of the lead contamination of air surrounding the AMAX smelter due to occurrence of elevated levels as much as 32 µg/m3 lead"--Abstract, page ii.
