It is also worthwhile to note that the pH scale is logarithmic; that is, a substance of pH of 6 is 10 times more acidic than another with a pH of 7. Generally, the pH of 5.6 has been used as the baseline in identifying acid rain, although there has been much debate over the acceptance of this value. Interestingly enough, a pH of 5.6 is the pH value of carbon dioxide in equilibrium with distilled water. Hence, acid ran is defined as any rainfall that has an acidity level beyond what is expected in non-polluted rainfall. In essence, any precipitation that has a pH value of less than 5.6 is considered to be acid precipitation.(2)

One of the main sources of acid rain is sulphur dioxide. Natural sources which make this gas are volcanoes, sea spray , rotting vegetation and plankton.(2) H

· If using an automatic dishwasher, let the dishes air dry.

There are new ways to reduce the amount of lowering acidity. Some of these ways are expensive and many of these ways are think you and I can do in our everyday life. Wet Flue Gas Desulfurization - This is a highly effective and cost efficient system of flue gas desulfurization. The wet scrubber is located downstream of the boiler, and consists of either limestone, lime, or sodium hydroxide. The flue gas enters the absorber and is re-emitted after being scrubbed, at which time the waste solids are removed and disposed of. Dry Scrubbing is another way. The process of dry scrubbing involves the contact between drying gas and the atomized liquid (alkaline based). Upon contacting the flue gas, the drying gas will convert the atomized droplets into a dry product that can be separated and disposed of. The dry scrubbing process requires less power to complete than wet scrubbing. The solid products of the scrubbing processes can be marketed as building materials. For instance, the end product flyash can be used in roadbase composition. Here are some of the ways we can fix the problem in our every day life:

· Share a ride with a friend or co-worker.

· Insulate and draft-proof your basement.

· If you have a forced-air furnace, change or clean its filters at least once a year.
