The purpose of this research is to investigate the role of respirable particulate matter (PM2.5) and associated metals in respiratory and cardiovascular responses in a cohort of boilermakers with and without chronic bronchitis. The experimental approach involves an epidemiological study employing a prospective, repeat-measurement design assessing several biological parameters in relation to exposure. PM2.5 levels are monitored continuously with personal Dust Trak monitors. Personal metal exposure (V, N, Cd, Mn, Cr, and Fe) will be measured daily. Boilermaker exposure to the fuel oil ash particulate will be related to the following:
• Airway inflammation, by measuring daily exhaled NO;
• Airflow obstruction–by measuring daily peak flow and weekly lung function (FEV1); and
• Cardiovascular function by measuring daily heart rate, heart rate variability, and blood pressure and weekly serum fibrinogen levels.
Workers during pre-exposure (layoff) serve as their own controls. Subjects with chronic bronchitis will be compared to non-symptomatics subjects. This project will be leveraged with funds from a National Institute of Environmental Health Sciences (NIEHS) grant.
This project was initiated under a previous grant (Grant No. R824834C002). The study is in compliance with the Institutional Review Board of the Harvard School of Public Health. Human consent procedures meet governmental guidelines. The study is in compliance with appropriate NUATRC and Environmental Protection Agency (EPA) quality assurance and quality control (QA/QC) guidelines.
Boilermakers (N = 40) have been monitored both in the field, at the site of two boiler overhauls, and in the apprentice welding school. Continuous monitoring of exposure, heart rate variability, and spirometry, and exhaled nitric oxide was performed during and away from work.
This is the first prospective study to use personal PM2.5 measurements to investigate their association with changes in heart rate variability (HRV) in a young cohort, and to investigate the association of several metals contained in PM2.5 with changes in HRV. Decreases in HRV and increases in heart rate associated with environmental and occupational PM2.5 exposures have been demonstrated. Individual metals (V, Mn, Pb) concentrations have been associated with increases in the heart rate variability index. Sampling and analyses of the filters for particulate matter and metals were completed. Metals analyses in the urine are ongoing. Data analyses for the study are ongoing.
The following activities will be performed in the next year:
· Correlation of analysis of metals in the urine and air samples;
· Evaluation of the association between fine particulate matter and respiratory effects (FEV1 and exhaled NO);
· Association between the metal components and respiratory end points;
· Assessment of the relationship between chronic respiratory disease and the cardiac responses to particulates; and
· Submission of the final report.
