The specie that was the most tolerant was the dragonfly and the least tolerant was the clam. Describe how acid precipitation affects ecosystems. Acid precipitation affects the ecosystem‚ for example‚ lowering ph in water when it falls into the lake which kills some aquatic organisms. What is an indicator species? How are indicator species used to assess pollution levels in the

Indoor & Outdoor Air Pollution Introduction: When people think about air pollution‚ they usually think about smog‚ acid rain‚ CFC’s‚ and other forms of outdoor air pollution. But did you know that air pollution also can exist inside homes and other buildings? It can‚ and every year‚ the health of many people is affected by chemical substances present in the air within

their crops. The fertilizer can be washed off from the rain and can carry it to a nearby stream or lake. The nitrates and phosphates that are being put in the water fertilize algae and cause its population to grow. (Lenntech 1998-) When the algae dies and gets eaten by bacteria the bacteria will use up the oxygen causing the oxygen levels to go down the fish in the water will die. Another type of pollution that can affect our water is acid rain. This is when gases and fossils after being burned go

other living species‚ and non-living objects. To better describe these harms‚ we refer to them as issues. They are issues we face daily one way or another. Let us for instance examine the atmospheric issues of acid deposition. This is a major issue with our environment‚ it is also known as acid rain‚ and first appeared after the industrial revolution. We can consider this to be an outdoor issue‚ since the process is completed outside‚ and the effects seem to take place outside as well. Nevertheless‚ we

environmental factors also contribute to this. Acid rain‚ for example‚ is formed when emissions of sulfur dioxide and nitrous oxide combine with moisture in the air to create acidic precipitation. This acid rain can acidify lakes and soils. It can also cause structural damage to buildings and monuments‚ especially those made of limestone or marble. Many of the historic structures in Washington D.C. are vulnerable to the destructive action of acid rain‚ with the U.S. Capitol Building itself showing

The statement says that pollution is a global responsibility‚ but first of all‚ in order to understand the statement and therefore argue the points of view‚ we must state what can be defined as Pollution. The Oxford dictionary states that to pollute an area is to… “…Destroy the purity or sanctity of; make foul or filthy; contaminate or defile…” There are many types of pollution‚ of which the most common is atmospheric pollution. Atmospheric pollution is generally caused by the emissions of substances

of all over the world die due to direct or indirect effects of air pollution. 3. Acid Rain: Acid raining is another effects of air pollution. Harmful gases like nitrogen oxides and sulfur oxides are released into the atmosphere during the burning of fossil fuels. When it rains‚ the water droplets combines with these air pollutants‚ becomes acidic and then falls on the ground in the form of acid rain. Acid rain can cause great damage to human‚ animals and crops. 4. Depletion of Ozone layer:

include carbonic oxide‚ carbon dioxide‚ hydrocarbon‚ sulfur dioxide ect‚ which really do harm to the environment to a large extent. They will lead to foggy weather‚ acid rain‚ acid soil and water and so on. What’s worse‚ the trees and flowers will not grow normally because of the the pollution. Many buildings‚ will be dissloved by the acid rain as well. Crops will no longer have gains. On the other hand‚ these chemical substances are closely related to our health. People who have taken in the polluted

less obvious. These costs are the effects fossil fuels have on our environment and on human health. Air pollution caused by the burning of coal and oil as well as dust in mines is causing problems for human health. The environment is suffering from acid rain‚ global warming and water and air pollution. Many times‚ the costs go unpaid for and unnoticed. It is imperative that we as a society take responsibility and strive to reduce the negative effects of fossil fuels on our environment. The global
