Miners working in poorly ventilated underground shafts are frequently exposed to diesel engine exhaust emissions, which contain high concentrations of both fine diesel particulate matter (DPM) and carbon monoxide gas.
Describe how chronic inhalation of diesel particulate matter (DPM) damages the respiratory system and reduces the efficiency of gas exchange in the lungs.
Explain how the inhalation of carbon monoxide from the exhaust gas reduces a miner's physical stamina and ability to perform heavy manual labor.
