Acid Rain


The damaging effects of acid rain on society is becoming overwhelmed with great amounts of
pollution from cars, factories and an large amounts of garbage. The immense amounts of
sulphur dioxide put into the air causes high levels of acid in the atmosphere. When this
sulphuric acid is absorbed into moisture in the air, then rain can be harmful to the
environment. Acid rain is destroying lots of things in our environment. It is hurting
lakes, air and thew rest of our ecosystem. Acid rain is killing lakes and decreasing the
number of animals in these lakes. Acid rain greatly lowers the amounts of pH in the water.
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 living in
these lakes. Also the high amounts of acid in the water can lead to fish being deformed.
They have messed up and out of shape backbones, flattened heads and strangely curved
tails. When there gets to be a lot of acid in the water, then there is barely anything
left besides rock bass, pumpkinseed and lake herring. As with sulphur 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 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.
In the air Anitrogen oxides react with ozone and some hydrocarbons in the presence of
sunlight to form photochemical smog, the kind of yellow-grey haze which it literally alive
and growing in stagnant air masses@ (Howard & Perley, 1980, p. 44). This smog carries
serious risk for respiratory disease and crop damage. The photochemical smog is also
causing the ozone layer to disintegrate. The ozone layer is becoming a part of this smog,
which is causing holes in it. An inordinate amount of sulphur dioxide is let into the air,
more than can be neutralized by nutrients in the air. Decrease in pH levels, photochemical
smog and depletion of the ozone layer are some effects of acid rain in the air. The
ecosystem is slowly eroding due to the increased amounts of acid in the soil. Acid in the
soil in causing the carbon dioxide respiration process to decelerate. In order for plants
to go through photosynthesis, they need carbon dioxide. When acid in the soil causing this
soil respiration to slow down, in turn it causes the photosynthesis process to slow down.
The soil also erodes when the pH levels drop. The acidic levels of the soil cause
nutrients in the soils such as aluminum to break apart and the soil to erode. Soil erosion
also causes a lower production of plants in the ecosystem. In the soil a process of decay
Acalled oligotrophication, means that fewer of the ions of acid are neutralized by the

  • Aluminum
    aluminum Aluminum is one of a number of soft metals that scientists call "poor" metals. It can be shaped and twisted into any form. It can be rolled into thick plates for armored tanks or into thin foil for chewing gum wrappers. It may be drawn into a wire or made into cans. Aluminum is a generally popular metal because it does not rust and it resists wear from weather and chemicals. (Bowman, 391) Aluminum is an element. Its atomic number is thirteen and its atomic weight is usually twenty-seven
  • Pollution and the Advance of Technology
    Pollution and the Advance of Technology Technology is a major part of everyone\'s life. Everyday we encounter technology at home, school and at work. We use this technology to better our lives. But do we really? With the advancing of technology also comes the issue of polluting the world we live in. We take the automobile for granted, but as we use it, we contribute to the growing pollution problem. Now in the year 2000, car companies have recognized the pollution problem, and have advanced thei

    acid rain3 Environmental Effects of Acid Rain Acidic deposition, or acid rain as it is commonly known, occurs when emissions of sulfur dioxide (SO2) and oxides of nitrogen (NOx) react in the atmosphere with water, oxygen, and oxidants to form various acidic compounds. These compounds then fall to the earth in either dry form (such as gas and particles) or wet form (such as rain, snow, and fog). Prevailing winds transport the compounds, sometimes hundreds of miles, across state and national borde

    Lupus Lupus is a chronic, autoimmune disease which causes inflammation of various parts of the body, especially the skin, joints, blood and kidneys. The body\'s immune system normally makes proteins called antibodies to protect the body against viruses, bacteria and other foreign materials. These foreign materials are called ANTIGENS. In an autoimmune disorder such as Lupus, the immune system loses its ability to tell the difference between foreign substances (antigens) and its own cells and tis
