In the RED is where acid rain is a Highest Risk ORANGE is medium Risk YELLOW is Low Risk



** Acid Rain ** As the name suggests, acid rain is just rain which is acidic. The rain becomes acidic because of gases which dissolve in the rain water to form various acids. About 70 percent of acid rain comes from sulphur dioxide (SO2), which dissolves into the water to form sulphuric acid. The rest comes from various oxides of nitrogen (mainly NO2 and NO3, collectively called NOx). (These figures are for Scandinavia - Scotland has a very similar ratio, while the north-eastern USA has 62 percent sulphuric acid, 32 percent nitric acid and 6 percent hydrochloric acid). These gases are produced almost entirely from burning fossil fuels, mainly in power stations and road transport.



Acid rain causes lakes and rivers to become acidic, killing off fish - all the fish in 140 lakes in Minnesota have been killed, and the salmon and trout populations of Norway's major rivers have been severely reduced because of the increased acidity of the water. Short-term increases in acid levels kill lots of fish, but the greatest threat is from long-term increases, which stop the fish reproducing. The extra acid also frees toxic metals which were previously held in rocks, especially aluminium, which prevents fish from breathing. Single-celled plants and algae in lakes also suffer from increased acid levels.



This pictures shows the damage Acid Rain has to our enviroment.

Acid Rain sadly caused this umbrella to go holey. Just look at the damage this devestating rain does to the umbrellas out there...
