Objective:
The objectives of the project are 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 method of this project is 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 origin of the source for these PAHs (indoor versus 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.
Progress Summary:
This research was funded by the NUATRC under its small grants New Investigators Award. The 2-year project began in August 1999, under a previous EPA grant (Grant No. R824834). It is expected to be completed by June 2002. The 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 EPA guidelines.
Ten homes in the Chicago area have participated in this study on a voluntary basis. They were selected based on the response to a household screening survey questionnaire. Indoor and outdoor air samples at these homes were concurrently collected once a month for a 14-month period. Each sampling lasted 46 hours at airflow rate of about 10 liters per minute (Lpm). Real-time monitoring and recording of the air quality (temperature, humidity, CO2) was completed during each sample, both indoors and outdoors. Carbon monoxide concentration in indoor air also was recorded. During each sample, a home status questionnaire was taken to register the household activities and events that may affect the PAH levels.
To date, a total of 223 air samples were successfully collected and analyzed, including 115 indoor and 108 outdoor samples. For each sample, 16 PAHs were measured using gas chromatography-electron impact mass spectrometer (GC/EIMS) with large volume injection using the programmable temperature vaporizing (PTV) technique. Analyses of the data are ongoing.
Future Activities:
The investigators will prepare a draft final report by April 2002. The report then will be subjected to an external peer-review process.
