Abstract

Acid rain is rain or any other form of precipitation which are wasted by various chemical compounds. The principal cause of acid rain are gases such as sulfur, nitrogen or carbon oxides which react with water in the atmosphere to produce acids. pH of acid rain is 4 or 4,5, as opposed to rain water, whose pH is around 5,5. Acidification isn’t constant or limited to certain areas. Primary it depends on amount of the toxic compounds which are emitted naturally (volcanoes, fires), but also from human sources. Toxic compounds are mobile because of the waves, the wind and movements of the clouds, and the organisms which live in areas where acid rains affect must adjust themself, move or instinct. Extremely big problem is that acidity strikes juvenile stages and embryos the most, as well as the most basic links of food chains, and therefore destroys complete ecosystem. This problem was spotted a long time ago, but nobody reacted on time, and now it takes a great effort, specialists and equipment to make a good plan for the recovery of our planet, and to achieve that, all primary contaminators (the whole mankind) must participate.
