This project will identify and evaluate the nanometer and ultrafine aerosols emitted by diesel-powered equipment and formulate control technologies to reduce the exposure of workers to these particles, thereby reducing the associated occupational health risks. The physical and chemical properties of the nanometer and ultrafine diesel aerosols will be characterized through a series of engine/dynamometer tests both at the NIOSH Lake Lynn Laboratory experimental mine and at participating active metal and coal mines. The knowledge obtained, from this study, will strengthen our understanding of the health implications related to exposure to diesel particulate matter and aid in assessing the potential of various control technologies for reducing this exposure
