Intake Fraction of PM₁₀ from Coal Mine Emissions in the North of Colombia.

ABSTRACT: Intake fraction was determined in this study to provide insight into population exposures to PM₁₀ that is effectively inhaled due to emissions of an opencast coal mine. We applied the CALPUFF model to a coal mine in Northern Colombia, which has 6 active pits with an annual production of 33.7 million tons. We estimated the intake fractions for 7 towns through the integration of dispersion model results over the population data. The resulting average intake fractions were between 6.13 × 10^-9 and 3.66 × 10^-8 for PM₁₀. 62.4% of the intake fractions in the domain were calculated within a 23 km radius from the coal mine and coved 44.3% of the total population in this area. We calculated an estimate point for morbidity impacts using standard epidemiolog
