Abstract
In a mountainous area of Yugoslavia, where a lead mine and smelter have been in operation for some 300 years, samples of new-fallen snow were obtained within three zones situated at increasing distances in different directions from the two centrally located stacks of the smelter, and were analyzed for their lead content. The lead content of new snow would be a factor of the quantities of lead in the air through which precipitation of moisture has occurred. The results confirmed the expectation that, with increasing distance from the source of lead emission, the snow contained consistently decreasing quantities of lead. Moreover, samples of new-fallen snow collected at altitudes that differed from that of the stacks yielded results that deviated from each other to such an extent as to alter significantly the negative correlation of the results with an increasing distance of the sampling sites from the stacks.
