متن کاملAcute lead poisoning associated with backyard lead smelting in Jamaica.
Long-term backyard smelting of lead in a district known as Mona Commons, Kingston, Jamaica, has produced lead burdens as high as 30 000 mg/kg in soils near to the smelter, and indoor dust loadings of 373 microg/f2 in the residents' home. The blood lead levels (BPb) of 107 children from the district were in the range 2.2-202 microg/dL. Fifty-nine per cent of these had BPb levels above 10 microg/...
متن کاملChemical speciation of lead dust associated with primary lead smelting.
The research presented in this article assessed geochemical factors relating to dust produced during primary lead smelting. Bulk dust samples and size-selective airborne dust samples were collected from four areas of a primary lead smelter and analyzed by X-ray diffraction and sequential chemical extraction. X-ray diffraction showed that the smelter dusts were composed primarily of sulfides, ox...
متن کاملDiscovering unrecognized lead-smelting sites by historical methods.
OBJECTIVES Our objective was to enumerate unrecognized former lead smelters in the United States. METHODS Defunct smelters were identified by historical research. The compiled list was compared with government registries of hazardous sites. Soil samples were taken from 10 sites. RESULTS Approximately 430 sites were unknown to the federal authorities. Only 5 of 319 sites were known to author...
متن کاملKidney effects in long term exposed lead smelter workers.
Occupational exposure to lead may cause kidney damage. This study was carried out on a cohort of 70 active and 30 retired long term exposed lead smelter workers. Their kidney function was compared with 31 active and 10 retired truck assembly workers who had no occupational exposure to lead. The lead workers had been regularly followed up with measurements of lead concentration in blood since 19...
