Objective:
The primary objectives of this research are:
- To characterize the distribution of exposures to selected volatile organic compounds (VOCs) for a subset of the U.S. population, by obtaining 48-hour measurements of personal exposure to selected VOCs for 1,000 individuals between the ages of 20 and 59 years, selected as a representative subsample of this subgroup of the U.S. population;
- To examine the relationship between personal exposure to selected VOCs and demographic, economic, and behavioral characteristics obtained from interview data; and to examine the variation in personal exposures of study subjects to VOCs in relation to demographic, economic, and behavioral factors.
During the three-year data collection period, exposures to VOCs for approximately 1,000 individuals were assessed through the use of personal exposure dosimeters (Model 3520 Organic Vapor Monitors, manufactured by 3M Company) that were worn by subjects for periods of 48-72 hours. Recruitment of participants into the NHANES survey during 1999 was somewhat lower than anticipated, but in 2000 and 2001, higher levels of response were achieved. The VOCs included in the project are the following: benzene, 1,3-butadiene, carbon tetrachloride, chloroform, 1,4-dichloroethylene, ethylbenzene, methylene chloride, styrene, tetrachloroethylene, toluene, trichloroethylene, o-xylene, m/p-xylene, MTBE, and chloroprene. The data set constitutes a profile of air toxics exposures for a segment of the US population, and also offers the opportunity to correlate these data both with health data obtained for this subset of the NHANES population, as well as the health data for the NHANES population sample of US residents aged 20 to 59 years.
Summary/Accomplishments (Outputs/Outcomes):
- This Project is a component of the National Health and Nutrition Examination Survey (NHANES) for the period 1999-2001.
- A pilot study was conducted from June 29 through August 9, 1998 to test procedures in an operational mode and to gather test data that were reviewed by collaborators.
- A Dress Rehearsal, designed to allow a final practice of all activities, was held in March, 1999, and the survey began in April 3, 1999.
- The VOC Project was conducted at 12 sites during 1999, and at 15 sites per year during 2000 and 2001. Each site was visited for a period of four to seven weeks.
- Two additional analyses of NUATRC VOC Project data were conducted to prepare the data for inclusion in the NCHS planned public data release: (1) to examine the effects of extended badge storage after exposure for up to 3 months on the reliability of concentration measurements obtained from Organic Vapor Monitor badges and (2) to meet the rigorous standards for quality control in order to include NUATRC VOC Project data in the NHANES public data release. These analyses found that, except for 1,3-butadiene and chloroprene, measurements of exposure for the target compounds exhibited very good stability. Additional review and analysis of quality control data derived from analyses were in addition to those originally estimated and budgeted in order to prepare the VOC project data for public release. NCHS approved the QA/QC data, and then conducted a general review of the data set.
- In October 2004, NCHS released the 1999 and 2000 NHANES VOC data set to the Center for review prior to its public release on the NCHS website. The Center contracted with Dr. Bill Spears, School of Public Health, at the University of Texas Health Science Center, San Antonio, and to Dr. Tom Stock, School of Public Health, at the University of Texas, Health Science Center, Houston, to assist in this quality assurance effort. The aims for this data review were: (1) to determine whether the environmental measurements were comparable with measurements from previous population studies of personal exposure of this type; and whether these measurements demonstrated the types of consistent relationships between compounds observed by other investigators; (2) to demonstrate the feasibility of performing appropriate analyses for groups of study subjects that involved exposure variables from the VOC Project and demographic variables from the main NHANES survey; and (3) to evaluate household and activity data obtained from the VOC Project study subject questionnaires and investigation of potential associations between these activities and personal exposures. Results of the review were consistent with findings from other studies of this type, as well as being consistent with his reviewers’ own experiences in investigating personal exposures to VOCs in numerous field studies.
