Exposure Pathway

Children are exposed to diesel exhaust in the air they breathe

  • Since it is dispersed throughout the atmosphere, it is a part of the background environment.
  • School-age children are at risk for additional exposures because many are transported by diesel-powered school buses
  • Further, because school buses travel and wait and park near school buildings, children who do not ride the buses but attend the school are exposed to higher concentrations in this vicinity.
