Nitrogen Dioxide or compound NO2 is a byproduct from cigarette smoke, combustible appliances that are unvented, kerosene heaters, and offgas from welding. This gas especially affects people with bronchial issues such as asthma, and  COPD chronic obstructive pulmonary disease. High exposure of NO2 can cause pulmonary edema, chronic bronchitis, and acute lung damage. 

IAQ Environmental tests for NO2 in the air. Our equipment is calibrated to detect dangerous gas levels. 


Nitrogen Dioxide:


Nitrogen Dioxide is a colorless, odorless gas that irritates the mucous membranes in the eye, nose, and throat and causes shortness of breath after exposure to high concentrations. There is evidence that high concentrations or continued exposure to low levels of nitrogen dioxide increases the risk of respiratory infection. There is also evidence from animals studies that repeated exposures to elevated nitrogen dioxide levels may lead, or contribute, to the development of lung disease such as emphysema. People at particular risk from exposure to nitrogen dioxide include children and individuals with asthma and other respiratory diseases.
