Diesel Exhaust

Diesel engines are a key part of the world’s transportation and industrial infrastructure, especially in heavy-duty applications. Despite the durability and efficiency of diesel engines, there have long been concerns about the environmental and human health impacts of diesel engine emissions, which include fine particulate matter (PM2.5), nitrogen oxides (NOx), and hydrocarbons (including some carcinogens). As part of its founding mission, HEI research has evaluated exposure and health effects in the ever-changing landscape of diesel engine emissions.
