Acrolein in Outdoor Air

Summary Indicator Report Data View Options

Acrolein in Outdoor Air by County, New Jersey, 2019

Why Is This Important?

Throughout the nation, mobile sources (e.g., cars, trucks, buses) account for a large fraction of acrolein emissions to the environment. Acrolein is emitted into the atmosphere through incomplete combustion of gasoline from automotive tailpipes. Acrolein causes eye irritation, burning of the nose and throat, and lung damage. These effects usually disappear after exposure stops. However, there is very little information about how exposure to acrolein affects people's health.

How the Measure is Calculated

Numerator:Modeled mean acrolein concentration in micrograms per cubic meter

How Are We Doing?

Several New Jersey counties exceed the health benchmark of 0.02 micrograms of acrolein per cubic meter of air. The highest reported concentration using modeled results can be found in Hudson County. Acrolein concentrations in ambient air throughout the state are also influenced by out-of-state emissions from both stationary and mobile sources.

What Is Being Done?

In the outdoor environment, acrolein is a byproduct of combustion and subject to the general controls on automobile and stationary sources. Industrial facilities that emit this chemical must obtain permits from the NJDEP Air Program and are also subject to state and federal air pollution control technology requirements.
