Objective:

The objectives of the research 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.

Approach:

The project was initiated by the Center in August 1999, under a previous EPA grant (Grant No. R824834C008), and will continue under this follow-on grant. Ten homes in residential south Chicago will be monitored, for 16 PAHs, once a month for 1 year. During each sample, a home status questionnaire was completed to record the household activities and events, which may have affected PAH levels.

Expected Results:

We expect to identify whether the source of these PAHs is indoors or outdoors. Because PAHs are toxic (they contribute to the development of lung and skin cancers, gastrointestinal, urologic, laryngeal, and pharyngeal malignancies, and enhance immune or allergic responses), identification of the concentration and source of PAHs will be helpful to design strategies to reduce exposure.
