Impact/Purpose:
Develop simple questionnaires and measures for input into models to classify children's exposures to CRPs, PM, and air toxics.
Quantify personal, indoor air, outdoor and ambient site concentrations for CRP/PM/air toxics for the participants in this pilot study.
Identify and model key factors contributing to the inter- and intra-personal variability between personal measures and corresponding indoor, outdoor, and ambient air concentrations for CRP/PM/air toxics.
Evaluate the contribution of ambient sources to indoor air and personal concentration measurements for CRP/PM/air toxics.
Apply the scientific tools developed and information gained from this pilot in the NCS to assess children's exposures.
Description:
Since 1980, there has been a 75% increase in the prevalence of asthma in children in the U.S.
A pilot study was conducted in a southeastern US city to develop and to evaluate methods and factors associated with asthmatic children's (< 6 yrs.) exposures to air pollutants. Observations support the need to collect data on activities and lifestyle factors in large-scale asthma studies to model asthmatic children's exposures and intake dose rates.
