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 value" is 40 μg /m. On March 2015, Brussels took the United Kingdom into court for breaching emissions limits of nitrogen dioxide at its coal-fired Aberthaw power stations in Wales. The plant operated under a permit allowing emissions of 0.0012 μg/m, which is more than twice the 0.000 5μg /m limit specified in the EU’s large combustion plant directive. Generally, long-term prognosis is helpful to survival of initial exposure to nitrogen dioxide. Some cases of nitrogen dioxide poisoning resolves with no observable symptoms and patient may be determined by pulmonary function testing. If chronic exposure causes lung damage, it could
