Health Indicator Report of Naphthalene in Outdoor Air
Naphthalene has been used as a household fumigant, such as in mothballs or moth flakes. Large amounts of naphthalene are used as a chemical intermediate to produce other chemicals. Exposure to naphthalene happens mostly from breathing air contaminated from the burning of wood, tobacco, or fossil fuels, industrial discharges, or moth repellents. Exposure to high levels of naphthalene may damage or destroy red blood cells. Children and adults have developed this condition, known as hemolytic anemia, after ingesting mothballs or deodorant blocks containing naphthalene. Symptoms include fatigue, lack of appetite, nausea, restlessness, and pale skin. The International Agency for Research on Cancer (IARC) classifies naphthalene as possibly carcinogenic to humans.
Naphthalene 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 naphthalene concentration for census tracts in a county using 2011 NATA data
NumeratorModeled mean naphthalene concentration in micrograms per cubic meter
How Are We Doing?Most New Jersey counties exceed the health benchmark of 0.029 micrograms of naphthalene per cubic meter of air. The highest ambient air concentration can be found in the northeast counties, as well as Mercer and Camden Counties.
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.
