Nitrogen dioxide is a chemical compound with the formula NO 2. One of several nitrogen oxides, ... Indoor exposure levels of NO 2 are, on average, ...
Exposure to high level of nitrogen dioxide may lead to inflammation of the mucous membrane and the lower and upper respiratory tracts. [11] The symptoms of acute nitrogen dioxide poisoning is non-specific and have a semblance with ammonia gas poisoning, chlorine gas poisoning, and carbon monoxide poisoning.
A recent study conducted by the University of California Davis found that adding nitrogen fertilizer to soil in California is contributing 25 percent or more to state-wide NO x pollution levels. [18] When nitrogen fertilizer is added to the soil, excess ammonium and nitrate not used by plants can be converted to NO by microorganisms in the soil ...
For nitrogen dioxide (NO 2), the guidelines set 10 μg/m 3 for the annual mean or 25 μg/m 3 for a 24-hours mean. [2] For sulfur dioxide (SO 2), the guidelines stipulate concentrations not exceeding 40 μg/m 3 24-hour mean. [2] For carbon monoxide concentrations not exceeding 4 mg/m 3 24-hour mean. [2]
Criteria pollutants that are due 18 months after an area has been designated include sulfur dioxide (SO 2), nitrogen dioxide (NO 2), coarse particle pollution (PM 10), fine particle pollution (PM 2.5), and lead (Pb). [9] Ozone (O 3) and carbon monoxide (CO) are due 24 months after designation. [9]
Nitrogen dioxide 2014 - global air quality levels ... At an ambient sea level atmospheric pressure of 1 atm (101.325 kPa or 1.01325 bar), the general equation is:
Mixed Oxides of Nitrogen ("MON"): solutions of nitric oxide in dinitrogen tetroxide/nitrogen dioxide. Nitric oxide, NO. Nitrogen dioxide, NO 2. Nitrous oxide, N 2 O.
[30] [31] Ground-level ozone, sulfur dioxide, nitrogen dioxide and carbon monoxide are especially harmful for senior citizens, children, and people with heart and lung conditions such as emphysema, bronchitis, and asthma. [14]
