Abstract
Because of the high level of cardiovascular diseases in the Kemerovo Region, it is extremely important to reveal a relation between exposition to dust from the coal industry and human health. One of the first steps for this disclosure is investigation into the physical and chemical properties of dust in the hospitals of Kemerovo (Kemerovo Region - Kuzbass), which is reported in this paper. It is found that the object analysed is a mixed type, not uniform, and contains organic and inorganic parts. The major mineral part is silica, which agrees with its content in fly ashes characteristic of the region. Constant concentration ratios of aluminium, silicon and manganese allow an assumption that the dust is built up by similar types of aluminosilicates containing manganese within the structure. Low amounts of sulphur and high amounts of calcium simultaneously indicate the presence of calcite and/or feldspar in the dust. High contents of sodium and calcium can be caused by the application of detergents. The dust is classified as PM0.1-PM1 according to particle sizes. The relationship of the properties of dust with the characteristics of the industrial orientation of the region is outlined.
