NO2 Emission Increases Associated with the Use of Certain Diesel Particulate Filters in Underground Mines
Emissions of and exposure to diesel particulate matter can sometimes be controlled through use of newer diesel engines, better engine maintenance, alternative fuels, or ventilation upgrades. Some mines may need to use diesel particulate filters, however. This has created concern about potential exposure to nitrogen dioxide (NO2) resulting from their use. Read More >
