Nitrogen Dioxide (NO2) Gas Detectors

Nitrogen dioxide (NO2) is an extremely toxic by-product of burning hydrocarbons. Major sources of NO2 are internal combustion engines (e.g., diesel engines) and thermal power stations. Other sources of nitrogen dioxide include petroleum and metal refineries, manufacturing industries, wastewater treatment plants, and coal-fired power stations.

Characteristics of Nitrogen Dioxide

Nitrogen dioxide is a yellow-brown gas with a characteristic pungent, acrid odor. Nitrogen dioxide is soluble in water, where it reacts to form nitric acid. NO2 can be found in industries where the burning of diesel fuel takes place. The most toxic component in diesel emissions is nitrogen dioxide.

Nitrogen dioxide exposure in low doses can irritate the eyes and throat or cause a headache, nausea, and gradual loss of strength. High doses of NO2 can cause pulmonary edema (water in the lungs) and death.
