Health effects of NO2
NO is a colorless, odorless and tasteless gas that has low toxicity. NO2, is. In addition to brown-red, color it smells bad and irritates it.
Both gases put into the atmosphere easily together. By sunlight or ozone is created of NO in this way easily NO2. The nitrogen oxides play an important role in the environmental acidification and photo-chemical smog formation.Introduction to Kyle Leon
They are the precursors of ozone, ammonia, and other photo-chemical substances such as PAN (proxy-acetyl nitrate). Just as SO2, NO2 and NO can travel over large distances.
Their adverse effects then also extend into remote areas. In Flanders, the road is the largest producer of nitrogen oxides (Knox): less than 47% of total emissions in 2004 is attributable to road traffic.
Almost as pollution (39%) plus the electricity industry (including refineries)
Health effects of NO2 difficult breathing, usually at concentrations from 1800 g/m3 in healthy individuals and 200-500 g/m3 in patients with asthma or chronic obstructive pulmonary disease (COPD). People with respiratory problems and small children are more sensitive to nitrogen.
Possible problems are worse lung function, acute respiratory disease, and damage to the lung tissue (high exposure) and increased susceptibility to infections. Adverse effects of especially NO2 in humans occur in short term exposure at high concentrations or by chronic exposure to lower levels.
