| Abstract/Contents: | Discusses the "mechanisms of soil dust generation and exposure, the characteristics of soil dust and some possible health effects of soil dust exposure." Lists natural and anthropogenic mechanisms of soil dust dispersion, including wind erosion, soil preparation, harvesting of crops, construction, and driving on unpaved roads. Details the composition of soil dust, listing the organic and inorganic compounds. Also mentions that "the physical size, shape, and density of [soil dust] particles determine how they will be trasnsported in the human respiratory tract [and] deposition sites within the respiratory tract vary according to a number of factors, including the aerodynamic diameter of the particle." Also states that "small particles are breathed deeply into the pulmonary region and therefore can be expected to present a greater risk than a comparable mass concentration of larger particles." Describes the impact of contaminated soil on human health. States that "excessive use and inappropriate storage of additives such as pesticides and fertilizers influence the composition of soil dust. Soil can act as a reservoir and carrier for toxic chemcials, which can increase occupational exposure to toxic chemicals." Details the pathways that allow for human exposure to toxic chemicals in soil, including "consuming food that has been grown in contaminated soil or water that has had contact with it, breathing in contaminated soil as suspended dust and having direct skin contact with the contaminated soil." Also mentions house dust as "another vehicle for toxic chemical exposure. When soil material containing toxic chemicals is transported inside or around the home, infants and toddlers are more susceptible to exposure. The soil materials accumulate most efficiently in carpets, where infants and toddlers spend significant portions of their time and engage in frequent mouthing activities." Describes different types of soil dust exposures, including occupational exposure, fugitive dust exposure, and direct soil contact." Details the health effects of soil dust, stating that "a large number of adverse respiratory health outcomes have been attributed to agricultural dust exposure. Dust exposure may affect the airways and, depending on the antigenicity of the matrial and host susceptibility, may result in asthma, an asthma-like syndrom, or chronic obstructive pulmonary disease. Pharenchymal disorders such as hypersensitivity pneumonitis may result from exposure to fungal spores." Lists methods of reducing exposure to soil dust such as source control, engineering control, and the use of personal protective equipment. |
