The purpose of this research effort is to study the personal exposures to urban air toxics experienced by a group of students living in New York City (NYC) and in Los Angeles (LA). The study will provide information on the roles of seasons and days of the week, different meteorological conditions, and daily activities on exposures to selected volatile organic compounds (VOCs), aldehydes, and metals on particles of < 2.5 microns (PM2.5) present in the environment. Soluble fractions of selected metals also will be assayed for correlations with source measurements. Exposure measurements will be made in indoor, outdoor, and personal environments. The investigators will relate these exposures to the apportionment of air toxics among area, point, and mobile sources, as well as non-anthropogenic sources.

Progress Summary:

This project commenced in December 1997, under a previous grant (Grant No. R824834C001), and was scheduled to be completed in December 2001. Because more work was needed to complete the study, it will continue under this follow-on grant through July 2002. The TEACH study is in compliance with the Columbia University’s Institutional Review Board guidelines and governmental human consent regulations. The quality assurance/quality control (QA/QC) procedures are in accordance with NUATRC and Environmental Protection Agency (EPA) guidelines.

Laboratory analyses on the NYC samples have been completed. Data processing on the NYC (winter) database also was complete aside from trace metals. Winter and summer field measurements in LA were successfully completed in 2001. Recruitment was based at the Jefferson High School located in an economically underprivileged community. Approximately 700 survey forms were completed at the school, and 40 subjects participated in the field-monitoring project. Laboratory analyses and data processing of the LA samples are ongoing.

Preliminary results of the TEACH study, specifically as they relate to the fine particulate matter (PM2.5) associated metals data, indicated elevated levels of Mn, Cu, and Cr in personal samples. Significantly high levels of Fe also were associated with personal samples. These were related to time spent in the subway station. These concentrations are consistent with elevated levels of Fe in the subway station air.

Exposure data are in the process of being analyzed descriptively for each toxic parameter being measured, by subject, city, season, and location. Season-specific activity patterns will be displayed. Multivariate analyses of activity patterns and home characteristics will be carried out across seasons and locales. Contributions of indoor and outdoor toxics to personal air toxic exposures will be assessed for the winter and summer seasons for both cities. Time/activity patterns and home ventilation rates will be examined for their effects on these relationships. Source apportionment will be analyzed via studies of the source categories suggested in the subject-based exposure data.

Future Activities:

The following activities will be conducted in the next year: (1) speciation of the fine particulate matter of LA samples; (2) analyses of the air exchange samples; (3) analyses of data; and (4) submission of the final report.
