Acid Rain :: Free Essay Writer

The Damaging Effects of acidic come down Modern society is bonnie overwhelmed with great amounts of pollution from cars, factories and an overabundance of garbage. The broad amounts of sulphur dioxide emitted into the air becomes high levels of cutting in the atmosphere. When this sulphuric acid is absorbed into moisture in the air, poignant peltingfalls can be damaging to the external environment. pungent rain is destroying the world=s lakes, air and ecosystem. Acid rain is killing lakes and decreasing the number of inhabitants in these fresh pee system bodies. Acid rain causes an ample deduction in the pH levels in the water. At a neutral level the pH in water should be close to seven, unless in these acidic water bodies the pH levels can be as low as tetrad. These pH levels of four contain more than than ten percent acids than that of normal rain and atomic number 53 thousand times more acid than neutral water. Each ten dollar bill the pH levels of lakes around Onta rio have become ten times more acidic. The high acid levels contained in lakes excessively causes a decrease in the number of fish dwelling in these lakes. Also Aacid produces chemical changes in the tune of the fish, and their basic body metabolism is altered (Howard & Perley, 1980, p. 24), and can cause deformities in these inhabitants. They have twisted and arched backbones, flattened heads and strangely cut tails. In pH levels of four there is little left in the lakes besides rock bass, pumpkinseed and lake herring. Affected fish are also in danger of becoming sterile, which would put the species at risk of becoming extinct. As with sulphur dioxide in rain, mercury is also discharged into the water. in that respect is a direct connection between the mercury rich lakes as there is with those with high acidic levels. This metal becomes concentrated in the blood and tissues of fish. Acid rain causes traumatic effects in natural lakes and rivers. Acid rain causes air quality to deteriorate. As in water, acid rain causes the pH levels in the air to decrease. The sulphur dioxide, which diffuses into the air, mixes with moisture causing the pH levels to drop from the normal level. Again, the normal level is somewhere around seven, yet in some acidic air masses the levels can be as low as three. These lowered pH levels form a photochemical smog in the atmosphere.
