A secondary irritant atmosphere is.
Health Effects. Most of the higher oxides of nitrogen are eye, skin, and respiratory tract irritants. Nitrogen dioxide is a corrosive substance that forms nitric and nitrous acids upon contact with water; it is more acutely toxic than nitric oxide, except at lethal concentrations when nitric oxide may kill more rapidly.Nitric oxide is a potent and rapid inducer of …
Particle pollution can come from two different kinds of sources — primary or secondary. Primary sources cause particle pollution on their own. For example, wood stoves and forest fires are primary sources. Secondary sources let off gases that can form particles. Power plants and coal fires are examples of secondary sources.The secondary pollutants caused by the presence of NO 2 in the atmosphere also have their own adverse effects. PANs are an irritant, nitric acid causes acid rain and particulate matter and O3 cause respiratory problems. Who and what is emitting NO x?
