Signature of Occupational Diesel Exhaust Exposure
“Human Study to Develop a Signature of Occupational Diesel Exhaust Exposure”
Strong scientific understanding of how emissions from diesel engines impact the lungs could improve policies and regulations protecting workers exposed to diesel exhaust. Accordingly, we are recruiting healthy volunteers who are non-smokers to participate in our study. Volunteers sit in a room for four hours and breathe either clean filtered air or air that contains pollution at various concentrations similar to occupational settings such as bus and ferry terminals where diesel engines are used. A respirologist assesses the volunteer's lung health and clinical samples are taken. We are equipped with advanced molecular biology tools to measure different molecules and compare samples from our volunteer subjects following exposure to clean air or diesel exhaust. Our research aim is to find a simple, clinically relevant strategy that can be used to measure the impact of diesel exhaust on workers' lung health. This knowledge will empower regulators, companies, and ultimately workers to better manage their health risks. Our research aims to provide specific data to help regulators to make informed decisions about the risks of diesel exhaust exposure.
