Acid rain is one of the major environmental threats since 19th century. Acidification of the rainwater is identified by the presence of sulphuric and nitric acids. Samples of rain, snow, cloud water, aerosols and soil were collected in Colorado to study the mechanisms of acid rain formation. In this way, oxides of sulfur and nitrogen form acids, which can damage materials and aquatic and terrestrial ecosystems. If there is further deterioration of PH levels below a certain low level, making it super acidic, the rain water simply comes to be called as acid rain. << The results proved that air quality in the city is classified from satisfying to good, with a slight variation caused by the meteorological conditions, the demographic growth, and the industrial transition.
