1,3-Butadiene in Outdoor Air

Summary Indicator Report Data View Options

1,3-Butadiene in Outdoor Air by County, New Jersey, 2019

Why Is This Important?

1,3-Butadiene is a volatile chemical with a gasoline-like odor. It is used in the production of rubber and plastics, and is also a byproduct of incomplete combustion. Motor vehicle exhaust is the largest source of butadiene in New Jersey air. Inhaling high concentrations of 1,3-butadiene for prolonged periods can cause central nervous system damage and the risk of heart disease and cancer. At concentrations in air likely to be encountered in New Jersey, 1,3-butadiene may irritate the eyes, nose, and throat. 1,3-Butadiene is a known human carcinogen.

How the Measure is Calculated

Numerator:Modeled mean 1,3-butadiene concentration in micrograms per cubic meter

How Are We Doing?

Several New Jersey counties exceed the health benchmark of 0.033 micrograms of 1,3-butadiene per cubic meter of air. The highest ambient air concentrations can be found in the northeast counties of Bergen, Essex, Hudson, and Union.

What Is Being Done?

Like carbon monoxide, 1,3-butadiene is a product of incomplete combustion, and its presence in automobile exhaust is controlled to some degree by catalytic converters. 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.
