Objective:

The overall objective of this research is to measure volatile organic compound (VOC) concentrations for personal exposure assessment by monitoring individuals, indoor and outdoor environments within a South Baltimore community in proximity to industrial emissions. The study was a response to community concerns over the potential health hazard resulting from the intensity and proximity of industrial sources. A sample of forty (40) adults and fifteen (15) children in forty homes in this community were monitored for indoor, outdoor, and personal exposures to VOCs. The substances measured included benzene, 1,3-butadiene, and carbon tetrachloride. In addition to monitoring individuals and environments in the community, control subjects (fifteen adult and child pairs) in a reference community were monitored. As a result of these measurements, source apportionment was attempted for these specific chemicals.

The specific objectives are to: (1) provide VOC exposure information to a concerned community; (2) apportion indoor and outdoor sources; and (3) evaluate benzene as an exposure biomarker.

The National Urban Air Toxics Research Center (NUATRC) support supplemented a previous U.S. Environmental Protection Agency (EPA) grant, which monitored 30 residents of the exposed community, and 15 residents of the comparison unexposed community with organic vapor monitor (OVM) VOC badges. Separately, the NUATRC support supplemented a National Institute of Environmental Health Sciences (NIEHS) first award to measure biomarkers of benzene exposure of the exposed community residents.

Progress Summary:

This project was developed in response to NUATRC Request for Applications (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. The study protocol was approved by the Johns Hopkins’ Institutional Review Board and the human subject consent is in compliance with government regulations. The study is also in compliance with appropriate quality control and quality assurance procedures as per NUATRC and EPA guidelines.

Sampling for the study and analyses of the VOCs were completed in the fall of 2001. During 2002, the investigators completed the analysis of the air exchange rates measurements and cotinine analysis. Analyses of urine samples for benzene metabolite, trans, trans-muconic acid (ttMA) were completed. For the remaining part of 2002, the investigators focused their efforts on data analysis and report preparation.

The draft final report was received at the Center in December 2002, and was reviewed by a team of external peer reviewers. A no-cost extension was granted through December 2003 for revision of the final report.

A revised final report which addressed the external peer review was received by the Center in September 2003. The report has been reviewed by the Scientific Advisory Panel (SAP) and is currently undergoing scientific editing. The study has been granted a no-cost extension through August 2004 in order to complete scientific editing and publication.

The study results show that the influence of industry on community air quality is undetected for most VOCs, although an industry impact (outdoor and indoor) was suggested for m, p-xylene and ethylbenzene. Indoor source contribution was indicated for most VOCs (11 of 15), and although the sample size was small, parent/child exposures were found to be associated. With dietary sorbic acid restriction, a marginal predictive association was seen for ttMA and benzene exposure.

Scientific editing of the revised final report has been completed. The final report is in press.

Future Activities:

We will publish the final report.
