Nitric oxide
The importance of NO in the environment arises from
the fact that it forms as a by-product during the combustion
of fossil fuels. Under the temperature conditions of internal
combustion engines and other combustion sources, nitrogen
and oxygen of the air react to form small quantities of NO:

Na + 02
2NO
Nitric oxide
When inhaled, NO passes from the lungs into the blood-
stream. There it interacts with the iron in hemoglobin, de-
creasing its ability to carry oxygen. What makes nitric oxide
so hazardous in the environment is that it reacts almost
immediately with oxygen to form NO,. When dissolved in
water, NO, reacts with water to form nitric acid and nitrous
acid, which are major acidifying components of acid rain.
