M​otor vehicle emissions are a major source of air pollution in urban areas and impact the lives of billions of people every day around the world.  Motor vehicle exhaust contains toxic chemicals that are harmful to people’s health when exposed at certain levels.  These toxic fumes also contribute to the formation of cancer causing smog in the atmosphere, which can affect very broad regional air sheds.

Teledyne API has several products specifically designed to meet the challenging demands of near-roadside air quality monitoring.  ​
