Per. 5 Acid Rain The Damaging Effects of Acid Rain Modern society is becoming overwhelmed with great amounts of pollution from cars, factories and an overabundance of garbage. The immense amounts of sulfur dioxide emitted into the air causes high levels of acid in the atmosphere. When this sulfur acid is absorbed into moisture in the air, poignant rainfalls can be damaging to the external environment. Acid rain is destroying the Worlds lakes, air and ecosystem. Acid rain is killing lakes and decreasing the number of inhabitants in these fresh water bodies. Each decade the pH levels of lakes around Ontario have become ten times more acidic. The high acid levels contained in lakes also causes a decrease in the number of fish dwelling in these lakes. Also Acid produces chemical changes in the blood of the fish, and their basic body metabolism is altered and can cause deformities in these inhabitants. They have twisted and arched backbones, flattened heads and strangely curved 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 sulfur dioxide in rain, mercury is also discharged into the water. There 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 sulfur 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.
