Title: VOC Exposure in an Industry Impacted Community
Investigators: Buckley, Timothy
Institution: Johns Hopkins University
EPA Project Officer: Stacey Katz/Gail Robarge,
Project Period: January 2, 2001 through December 31, 2005 (Extended to December 31, 2008)
Project Period Covered by this Report: January 2, 2001 through December 31, 2002
RFA: Mickey Leland National Urban Air Toxics Research Center (NUATRC) (1997)
Research Category: Targeted Research , Air Quality and Air Toxics
Description:
Objective:The objectives of the project are to: provide VOC exposure information to a concerned community, apportion indoor and outdoor sources, and evaluate benzene as an exposure biomarker.
The goal of this project is to measure VOC concentrations for personal exposure assessment by monitoring individuals, and indoor and outdoor environments, within a South Baltimore community in proximity to industrial emissions. The study is a response to community concerns over the potential health hazard due to the intensity and proximity of industrial sources. A sample of 40 adults and 15 children in 40 homes in this community will be monitored for indoor, outdoor, and personal exposures to VOCs. The substances to be measured include benzene; 1,3-butadiene; and carbon tetrachloride. In addition to monitoring individuals and environments in the community, control subjects (15 adult and child pairs) in a reference community will be monitored. As a result of these measurements, source apportionment will be attempted for these specific chemicals.
The NUATRC support supplements a previous EPA grant, which will monitor 30 residents of the exposed community, and 15 residents of the comparison unexposed community with organic vapor meter (OVM) VOC badges. Separately, the NUATRC support supplements a National Institute of Environmental Health Sciences (NIEHS) award to measure biomarkers of benzene exposure of the exposed community residents.
Progress Summary:This project was initiated on August 1999, under a previous EPA Grant (Grant No. R824834C003). It 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. Currently, the project is scheduled to be compete by June 2002.
The study protocol was approved by the Johns Hopkins University Institutional Review Board and the human subject consent is in compliance with government regulations. The study also is in compliance with NUATRC and EPA quality assurance/quality control (QA/QC) guidelines.
During this project period, the investigators compared the sensitivity, recovery, and precision of air monitoring using OVM badges to that of the University of Texas, where the technique was originally developed. The results indicated favorable correlation between the two laboratories after Dr. Buckley switched to a new GC/MS instrument.
Sampling for the study and analyses of the OVM badges was completed in the fall of 2001. Preliminary distribution of the air toxics between indoor, outdoor, and personal were presented for both the control and target communities. These results indicated that for all the compounds studied there was no statistically significant difference in distribution between the target and control community, except for xylenes. Elevated levels of xylenes were observed in the target community compared to the control community. Analyses of the data are ongoing.
Future Activities:During the next year, the following activities will be performed:
· Analysis of the air exchange rates measurements, cotinine, and questionnaire data are still pending;
· Analyses of results on benzene biomarkers; and
· Submission of the final report.
