(1) This report summarizes the results of baseline neurologic testing in a group of apparently healthy workers from a secondary lead smelter and a group of controls from nearby aluminum processing plants.
(2) Fifty-eight households were studied in the Red Pond community, the site of the established smelter and several backyard smelters, and 21 households were studied in the adjacent, upwind Ebony Vale community in Saint Catherine Parish, Jamaica.
(3) Hair arsenic analysis in people living in two locations near an ore smelter and a refinery indicated high-levels compared to those of individuals residing in nonpolluted areas.
(4) Twenty-one workers from a Swedish smelter were selected on the basis of exposure to arsenic dust for more than 14 years and a previously (three years earlier) recorded subnormal FSP during local cooling.
(5) Pulmonary fibrosis has not been shown to be a significant problem in aluminum smelter workers.
(6) The mortality experience of all pensioners from a copper smelter who were aged 65 or over between 1949 and 1973 has been studied.
(7) The following forms of aluminosis should be distinguished: 1) simple accumulation in central nervous system which occurs in persons over 65 years; 2) aluminum accumulation in Alzheimer disease, in severe form of presenile and senile dementia; 3) dialysis aluminum encephalopathy; 4) non-dialysis infantile encephalopathy; 5) aluminum encephalopathy in total parenteral nutrition; 6) iatrogenic dialysis aluminum osteodystrophy; 7) jatrogenic peritoneal aluminosis; 8) aluminum pneumoconiosis of an occupational origin; 9) bronchospastic syndrome in aluminum smelter workers.
(8) Primary lead smelters within the new lead belt have been identified as potential sources of cadmium as well as lead, zinc, and copper.
(9) Close to the smelters tree species accumulated more foliar fluoride than shrub species, which in turn accumulated more foliar fluoride than herb species.
(10) A cohort of 3,916 Swedish copper smelter workers employed for at least 3 months between 1928 and 1967 was followed up through 1981.
(11) Several cases of parkinsonism were found in a ferromanganese smelter after the ventilation system had broken down and had not been repaired for eight months in 1985.
(12) An increased mortality from lung cancer, cardiovascular disease, haematolymphatic malignancy and cirrhosis of the liver has been reported among smelter workers and others exposed to arsenic.
(13) Epidemiological studies have shown increased lung cancer risks in urban areas and in communities near some types of industries, such as non-ferrous smelters.
(14) Anticancer properties have been shown in occupationally exposed copper smelter workers, dietary investigations and experimental studies.
(15) Separation, final concentration and refining of by-product arsenic as the trioxide is achieved at smelters.
(16) Data were gathered from questionnaires distributed at public hearings regarding proposed air pollution standards for an arsenic emitting copper smelter located in Tacoma, Washington.
(17) The smelter was located on Mount Holly Plantation in South Carolina, and concentrations of skeletal fluoride in the deer collected at Mount Holly increased approximately five-fold 3 yr after the operation began.
(18) Occupational lead poisoning and environmental contamination were evaluated at a lead scrap smelter.
(19) The Progressive party was also instrumental in pushing through the construction of a large-scale power plant to feed an aluminium smelter owned by Alcoa.
(20) To explore the role of arsenic as a human carcinogen, the respiratory cancer mortality experience (1938 to 1977) of 8,045 while male smelter employees in Montana was examined relative to cumulative exposure to arsenic trioxide and was compared with that of the white male population of the same region.
