The Toxic Power of Nitrogen Dioxide

Nitrogen Dioxide (NO2) is a reddish brown gas which is due to the absorption of light in the visible spectrum. A chemical characteristic is that it is a poisonous gas, and if reacting with the moisture in the air, it forms nitric acid, which can cause acid rain [2]. It is emitted from the burn ing of fuel, such as from cars, factories, or any road off equipment. It is known as a major air pollution that contributes to particulate matter, which affects airways in susceptible, causing or worsening asthmatic symptoms.




 
 
 

Some common scientific names of NO2 include Nitrogen (IV) Oxide or Nitrogen Peroxide. 

Some common uses of Nitrogen Dioxide in the past & present include its use in Welding, Fertilizer, Dye & Bleaching Agent. Doing some research on its uses today, welding was a prominent area where exposure is above average and affects the respiratory health of workers. 

-Welding: In the process of welding, nitrogen dioxide can be created as a byproduct especially those that are involved in high temperatures and combustion being that when metal surfaces are heated nitrogen from the surrounding air can react with the oxygen at the high temperatures to create NO2 and they can contribute to the fumes and emissions that are produced during welding [9]. This can pose a danger in the workplace, exposing yourself to NO2 and other welding fumes being it should be very minimized. This is a common practice especially in welding, being that there are safety protocols that are incorporated into jobs, such as welding. The level of effect one will experience from NO2 depends on the exposure time and level of nitrogen dioxide in the air.















This website explains some of the effects that NO2 can expose to welders, including impacting the lower respiratory tract & lungs, which can cause asthmatic symptoms to be present, as well as vomiting and even possibly fatality if the concentration is too high.
