Abstract
Exposure assessment is an important part in environmental epidemiology for determining the associations of environmental factors with health effects. One of the greatest challenges for personal exposure assessment is associated with peoples' mobility during the day and spatial and temporal dynamics of air pollution. In this study, the impact of PM10 (particulate matter less than 10 μm) on allergy risk among adults was assessed using objective methods of exposure assessment. The primary objective of the present study was to estimate personal exposure to PM10 based on individual daily movement patterns. Significant differences between the concentration of PM10 in different microenvironments (MEs) and personal exposure to PM10 were determined. Home exposure accounted for the largest part of PM10 exposure. Thirty-five percent of PM10 exposure was received in other non-home MEs. Allergy risk increased significantly with increasing exposure to PM10. Adults exposed to the highest levels of PM10 exposure had a twice-higher risk of allergies than adults exposed to the lowest levels of PM10 exposure. The study results have practical relevance for exposure assessment to environmental factors and its impact on health effects.
