This essay Acid Rain has a total of 1226 words and 7 pages.
Acid rain is a serious problem with disastrous effects. Each day this serious
problem increases, many people believe that this issue is too small to deal with
right now this issue should be met head on and solved before it is too late. In
the following paragraphs I will be discussing the impact has on the wildlife and
how our atmosphere is being destroyed by acid rain.
Already 140 Ontario lakes are completely dead or dying. An additional 48 000 are
sensitive and vulnerable to acid rain due to the surrounding concentrated acidic
ACID RAIN CONSISTS OF....?
Canada does not have as many people, power plants or automobiles as the United
States, and yet acid rain there has become so severe that Canadian government
officials called it the most pressing environmental issue facing the nation. But
it is important to bear in mind that acid rain is only one segment, of the
widespread pollution of the atmosphere facing the world. Each year the global
atmosphere is on the receiving end of 20 billion tons of carbon dioxide, 130
million tons of suffer dioxide, 97 million tons of hydrocarbons, 53 million tons
of nitrogen oxides, more than three million tons of arsenic, cadmium, lead,
mercury, nickel, zinc and other toxic metals, and a host of synthetic organic
compounds ranging from polychlorinated biphenyls(PCBs) to toxaphene and other
pesticides, a number of which may be capable of causing cancer, birth defects,
or genetic imbalances.
COST OF ACID RAIN
Interactions of pollutants can cause problems. In addition to contributing to
acid rain, nitrogen oxides can react with hydrocarbons to produce ozone, a major
air pollutant responsible in the United States for annual losses of $2 billion
to 4.5 billion worth of wheat, corn, soyabeans, and peanuts. A wide range of
interactions can occur many unknown with toxic metals.
In Canada, Ontario alone has lost the fish in an estimated 4000 lakes and
provincial authorities calculate that Ontario stands to lose the fish in 48 500
more lakes within the next twenty years if acid rain continues at the present
rate.Ontario is not alone, on Nova Scotia\'s Eastern most shores, almost every
river flowing to the Atlantic Ocean is poisoned with acid. Further threatening a
$2 million a year fishing industry.
Acid rain is killing more than lakes. It can scar the leaves of hardwood forest,
wither ferns and lichens, accelerate the death of coniferous needles, sterilize
seeds, and weaken the forests to a state that is vulnerable to disease
infestation and decay. In the soil the acid neutralizes chemicals vital for
growth, strips others from the soil and carries them to the lakes and literally
retards the respiration of the soil. The rate of forest growth in the White
Mountains of New Hampshire has declined 18% between 1956 and 1965, time of
increasingly intense acidic rainfall.
Acid rain no longer falls exclusively on the lakes, forest, and thin soils of
the Northeast it now covers half the continent.
Glossary and DefinitionsGlossary and Definitions Distribution: Drug distribution is the process by which a drug reversibly leaves the blood stream and enters the interstitium (extracellular fluid) and/or the cells of the tissues. The delivery of a drug from the plasma to the interstitium primarily depends on blood flow, capillary permeability, the degree of binding of the drug to plasma and tissue proteins, and the relative hydrophobicity of the drug. Excipient: Vehicle. A more or less inert substance added in a prescr

Organic ChemistryOrganic Chemistry Organic Chemistry branch of chemistry in which carbon compounds and their reactions are studied. A wide variety of classes of substances—such as drugs, vitamins, plastics, natural and synthetic fibers, as well as carbohydrates, proteins, and fats—consist of organic molecules. Organic chemists determine the structures of organic molecules, study their various reactions, and develop procedures for the synthesis of organic compounds. Organic chemistry has had a profound effect on

CarbonCarbon Carbon is one of the most important chemical elements. Industry uses it in a wide variety of products, and all living things are based on carbon. Without carbon, life would be impossible! Yet carbon makes up less than 0.03 percent of the earth’s crust. Pure carbon exists in nature in the form of diamonds, and in graphite. Both forms are pure carbon with different crystal structures. Another form of pure carbon, called amorphous carbon, consists of graphite-like particles too tiny to see w
Organic CompoundsOrganic Compounds Chemists observed that there were two types of substances. Those from non-living matter and those from living matter. They were classified into two categories which include inorganic substances and organic substances. Many similar properties were observed by the Chemists. Most inorganic substances were observed to change very little, if any, when heated. Also, organic substances were thought to be produced only by living organisms. Later in time organic substances were studied
