Sulfur dioxide is a noticeable component in the atmosphere, especially following volcanic eruptions. According to the United States Environmental Protection Agency, the amount of sulfur dioxide released in the U.S. per year was: Sulfur dioxide is a major air pollutant and has significant impacts upon human health. In addition, the concentration of sulfur dioxide in the atmosphere can influence the habitat suitability for plant communities, as well as animal life. Sulfur dioxide emissions are a precursor to acid rain and atmospheric particulates. Due largely to the US EPA’s Acid Rain Program, the U.S. has had a 33% decrease in emissions between 1983
Nitrogen dioxide poisoning Nitrogen dioxide poisoning Nitrogen dioxide poisoning is the illness resulting from the toxic effect of nitrogen dioxide (). It usually occurs after the inhalation of the gas beyond the threshold limit value. Nitrogen dioxide is reddish-brown with very harsh smell at high concentrations. It is colorless and odorless at lower concentration but still harmful. Nitrogen dioxide poisoning depends on the duration, frequency, and intensity of exposure. Nitrogen dioxide is an irritant of the mucous membrane linked with another air pollutant that causes pulmonary diseases such as OLD, asthma, chronic obstructive pulmonary disease and sometimes acute exacerbation of COPD and in
