Health Indicator Report of Chromium(VI) in Outdoor Air
Chromium is a naturally occurring element found in rocks and soil. It can exist in several different forms. The metal form, chromium(0), is used for making steel. Chromium(VI) and chromium(III) are used for chrome plating, dyes and pigments, leather tanning, and wood preserving. Chromium(III) is an essential nutrient that helps the body use sugar, protein, and fat. Breathing high levels of chromium(VI) can cause irritation and ulceration in the lining of the nose, and difficulty in breathing. Skin contact with chromium(VI) compounds can cause skin ulcers and allergic skin reactions. Chromium(VI) compounds are known human carcinogens. In workers, inhalation of chromium(VI) has been shown to cause lung cancer.
Chromium (VI) Concentrations in Outdoor Air, by New Jersey County, 2011 NATA
NotesData Source: National-scale Air Toxics Assessment (NATA), 2011 and NJDEP Division of Air Quality
- U.S. Environmental Protection Agency (EPA)
- Bureau of Air Monitoring, New Jersey Department of Environmental Protection
DefinitionMean of modeled annual average chromium(VI) concentration for census tracts in a county using 2011 NATA data
NumeratorModeled mean chromium(VI) concentration in nanograms per cubic meter
How Are We Doing?Numerous New Jersey counties exceed the health benchmark of 0.083 nanograms of chromium(VI) per cubic meter of air. The highest ambient air concentrations can be found mostly in the central and western regions of the state.
What Is Being Done?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.
