Q���)ߣ*Js�/�. Policy suggestions are made. Air pollution is a major environmental problem that has a range of negative impacts including human health, damage to ecosystems, food crops and the built environment. The acids like H 2 SO 4, HNO 3, HCl, H 2 CO 3 get mixed with rain water and fall down on the earth in the form of acid rain. Atmospheric pollutants, particularly oxides of sulphur and nitrogen, can cause precipitation to become more acidic when converted to sulphuric and nitric acids, hence the term acid rain.
