OBJECTIVE The Bunker Hill mine in Idaho operated from 1886 to 1981. In the 60's and 70's it provided approximately 25% of the primary lead in the United States. Women first began working on the production and maintenance lines in 1972. This study examines the impact of menopause and several occupational and lifestyle factors as determinants of blood and bone lead levels among 73 female former s...

lead has been recognized as an environmental pollutant of cancer for humans for livings for years. the lead concentration in biological cycles seems to depend on several factors, such as soil properties, plants species, and water properties as well as other factors. the objective of this study was to assess the rate of mobility and determine its effect on blood indices around the feyz abad – le...

The mining industry is among the top ten industries nationwide with high occupational injury and fatality rates, and mine rescue response may be considered one of the most hazardous activities in mining operations. In the aftermath of an underground mine fire, explosion or water inundation, specially equipped and trained teams have been sent underground to fight fires, rescue entrapped miners, ...

The Pb isotopic compositions for 51 spots of melt glass in 11 samples of trinitite have been determined by laser ablation multicollector inductively coupled plasma mass spectrometry (LA-MC-ICP-MS). Trinitite glass yields a large range of Pb isotopic compositions (i.e., (206)Pb/(204)Pb = 17.08-19.04), which reflect mixing between industrial Pb from materials used in the Trinity test and natural ...

inorganic lead compounds are used most widely in paint and pigment industries. because of exposure to lead dust in workers in a copying center, we compared blood lead levels in these workers to normal individuals and investigated the relationship between job tenures of the workers and their blood lead levels. this survey was performed on 20 simple workers in a copying center of tehran universit...

Coal is mined in every country which is mainly used to generate electricity. Thousands of mine workers were killed every year due to many disasters takes place inside coal mine. These accidents are caused mainly due to the leakage of poisonous gas [2] present in the mine. Especially developing countries face a poor safety system for mine workers. Hence it requires a safety monitoring system [1]...

The exposure of mine workers to diesel particulate matter (DPM) and gases is an issue of great concern to the underground mining community in the United States. Approximately 30,000 underground miners are potentially exposed to high concentrations of DPM. In January of 2001, the U.S. Mine Safety and Health Administration (MSHA) promulgated rules setting compliance standards for both underground...
