متن کاملOccupational hypersensitivity pneumonitis in a smelter exposed to zinc fumes.
A smelter exposed to zinc fumes reported severe recurrent episodes of cough, dyspnea and fever. Bronchoalveolar lavage showed a marked increase in lymphocytes count with predominance of CD8 T-lymphocytes. Presence of zinc in alveolar macrophages was assessed by analytic transmission electron microscopy. This is the first case of recurrent bronchoalveolitis related to zinc exposure in which the ...
متن کاملDaily soil ingestion estimates for children at a Superfund site.
Ingestion of contaminated soil by children may result in significant exposure to toxic substances at contaminated sites. Estimates of such exposure are based on extrapolation of short-term-exposure estimates to longer time periods. This article provides daily estimates of soil ingestion on 64 children between the ages of 1 and 4 residing at a Superfund site; these values are employed to estimat...
متن کاملSoil ingestion estimates for children residing on a superfund site.
Soil ingestion estimates were obtained from a stratified, simple random sample of 64 children aged 1-4 years residing on a superfund site in Montana. The study was conducted during the month of September for 7 consecutive days. The study utilized a mass-balance methodology in which eight naturally occurring soil tracers (Al, Si, Ti, Ce, Nd, La, Y, and Zr) believed to be poorly absorbed by the g...
متن کاملNatural attenuation of zinc pollution in smelter-affected soil.
Previous synchrotron X-ray microprobe measurements of Zn speciation in contaminated and uncontaminated soils have identified phyllosilicate as the main sequestration phase. The emphasis now is focused on comparing the nature and properties of neoformed and geogenic phyllosilicate species to understand natural attenuation processes. Refined structural characterization of the two types of Zn-cont...
