Objective:

The objectives of the project were to: (1) assess relative contributions from outdoor sources to indoor polycyclic aromatic hydrocarbons (PAHs) in urban homes; (2) identify major sources and estimate emission rates; and (3) examine factors that control/modify indoor PAH concentrations.

The overall approach of this project was to measure the concentrations of 16 selected PAHs in the indoor and outdoor environment of 10 homes in a residential area of south Chicago once a month for 1 year. Using these measurements and different models, the investigator will determine the source for these PAHs as coming from indoor or outdoor sources. Because PAHs are toxic (contributing to the development of lung and skin cancers, gastrointestinal, urologic, laryngeal, and pharyngeal malignancies, and enhance immune or allergic responses), identification of the concentrations of PAHs in an indoor environment as well as accurate source apportionment of the contributions from indoor and outdoor sources will be helpful in designing strategies for reduction of these exposures.

Summary/Accomplishments (Outputs/Outcomes):

This project was developed in response to NUATRC RFA 98-03, "NUATRC New Investigators Small Grants Program," intended to foster the development of short-term research projects on exposures/health effects of urban air toxics by new investigators.

This project is in compliance with the University of Illinois' Institutional Review Board for use of human subject protocols and human consent regulations. The project also is in compliance with appropriate quality assurance and quality control procedures as well as NUATRC and Environmental Protection Agency (EPA) guidelines.

During the first year of the study, home questionnaire surveys, validation of sampling, and chemical analysis procedures were completed. Work during the following months involved indoor/outdoor sampling, chemical analysis, onsite survey data collection, and PAH indoor source sampling and analysis.
