Elevated levels of nitrogen dioxide in the atmosphere can lead to___________________?
Show answer Hide answer
Answer: B. Bronchitis
Explanation
Nitrogen dioxide is a reactive pollutant gas that penetrates deep into human lung tissue upon inhalation. This chemical irritation causes inflammation of the bronchial tubes and impairs normal respiratory function. Chronic exposure to elevated nitrogen dioxide levels is a major environmental trigger for clinical bronchitis. Nitrogen dioxide is produced primarily by high-temperature combustion processes in vehicle engines and power plants. Bronchitis is characterized by inflammation of the mucous membranes lining the bronchial airways in the lungs. Air quality indexes use nitrogen dioxide concentrations to issue public health warnings for sensitive populations.
Urban traffic congestion frequently elevates atmospheric nitrogen dioxide, worsening respiratory health for residents. Environmental protection agencies enforce strict emission controls on automobiles to curb bronchitis and asthma rates. Occupational health guidelines protect industrial workers from breathing harmful nitrogen oxide fumes on site. Cancer is primarily associated with carcinogenic hydrocarbons and radioactive pollutants rather than nitrogen dioxide. Asphyxiation is caused by simple asphyxiant gases like nitrogen or carbon monoxide displacing breathable oxygen. Corrosion refers to material degradation of metals rather than a human health disease caused by nitrogen dioxide.
