[Quantified study on human health impact caused by coal-burning air pollution in China].

To develop the mathematics model of exposure to coal-burning pollution; To confirm the exposure level of coal-burning pollutants by source analysis of atmospheric particulates; To establish the quantilification technology and methods of human health impact. Combinating the methods of epidemiology, environmental chemistry and contaminated aerography. We obtained the data of human historical expose to PM10, PM2.5, and Bap etc. that can't be obtained from the general inspect and the contribution rate of coal-burning as well as the status of coal-burning air pollutants. Confirming the degree of human health impact due to coal-burning pollutants, which included: The occurrence risk of respiratory symptoms and COPD of adults in heavily polluted area was 1.7 and 1.5 times of that of relatively clean area respectively; FVC and FEF50 of pupils decreased 194 ml and 172 ml respectively with the increasing of every unit of the Ln(PM10). FVC and FEF50 of pupils decreased 69 ml and 119 ml respectively with the increase of every unit of the Ln(SO2). Both the indices of non-specific and humoral immunity of pupils in heavily and medium polluted areas were worse than those in relatively clean area.
