Nitrogen oxide spoils the environment when it reacts with oxygen; however, the catalytic converter breaks it up, reducing the amount of nitrogen oxide being released. In the reaction 2CO + O2 → 2CO2, oxygen is added to carbon monoxide to create carbon dioxide, which is practically harmless. Oxygen is also added in the reaction CxH2x+2 + [(3x+1)/2]O2 → xCO2 + (x+1)H2O to unburnt hydrocarbons in order to create carbon dioxide and water, which are again harmless. Catalytic converters play a major role in assisting in the reactions in order to change the products by rearranging and breaking up the
Acid Rain If it was possible to peer into the future and see the environmental consequences of mankind’s actions, humans’ harmful contributions to the highly acidic rain levels would be apparent. Seeing the possibility of a tragic environment in the future would change the ways we treat our environment today and forever. The environment receives its main punishments from a variety of sources, ranging from car smog to industrial smog and waste. Acid rain, fog, sleet and snow all have severely harmful affects on our environment. In order to protect our environment, humans need to be conscious of the results of their actions and act responsibly to slow down, if not stop, the negative effects of acid rain on our plant, animal and human life.
International treaties are present to stop this. The long range transport of atmospheric pollutants has been agreed like Sulfur Emission Reduction Protocol l under the Convention on Long-Range Trans boundary Air Pollution. Most of European countries, Canada and America have signed these treaties to fight against the acid rain. Everyone can help the environment from acid rain by spreading the awareness. Conserve the energy whether it’s used in your car, home or work place try to save electric energy switch off the unnecessary lights and try to limit the use of air conditioners.
When there is a lage amount of acid rain that falls in an area over a period of time, it can hurt the environment for all of the creatures living there. Acid rain can make a lake acidic which will most likely kill off a majority of the animals living in that lake. (McCormick 16) This happens all over the world. Michael Hopkin a reporter, and the author of “Acid rain still hurting Canada” states that, “Lakes and waterways in North America are struggling to recover from the effects of acid rain, despite reduced emissions of the pollutants that cause it. Without further cuts, it could be millennia before the worst-affected sites recover, say environmentalists.” It can also kill the animals that depend on the lake for food.
To decide whether tougher legislation should be implemented, one must first understand the details of what exactly acid rain is. Acid rain is a result of mankind's carelessness. It travels a long one of the most efficient biogeochemical cycles on earth, the Hydrologic Cycle. This allows acid rain to distribute itself further away from it's source causing more than local problems. Sulfur Dioxide (SO2) is released by fossil fuels when they undergo combustion.
The interaction between the water droplets and the carbon dioxide in the atmosphere, and to a lesser extent, from chlorine which is derived from the salt in the sea, gives rain an average pH of about 5.6, making even clean rain slightly acidic. Other natural sources of acids and bases in the atmosphere may lower or raise the pH of unpolluted rain. However, when rain contains pollutants, especially sulfur dioxide and nitrogen oxides, the rain water can become very acidic. Acid rain does not account for all of the acidity that falls back to earth from pollutants. About half the acidity in the atmosphere... ... middle of paper ... ...cellent idea.
Lakes are also greatly affected by contaminated precipitation. It has been discovered that some twenty thousand lakes have been turned acidic through groundwater contamination by acid rain. Fish start to die at around a pH of below 5.6. There are natural buffers such as calcium and lime in lakes to help neutralize these acids. If there aren’t enough buffer materials, or they are completely neutralized by the acids, the pH will not get better, and the lake will become sterile (Public 22.)
Though human causes are principally responsible for acid deposition, natural sources such as fires, lightings, bacterial decomposition, and volcanic eruptions also enhance acid deposition. For instance, the eruption of Mount St Helen’ released sulfur dioxide as much as a coal burning power plant does in a year in 1980. Once sulfur dioxide and nitrogen oxides have been released into the air, they can be carried by ... ... middle of paper ... ... production is not enough for a country. Therefore scientists keep working on finding better solutions to reduce sulfur dioxide and nitrogen oxides. Apart from these, individuals can contribute to reduce acid deposition by using public transport, not wasting electricity, using polar power and batteries.
I chose it because we are subjected to precipitation all the time. I was interested to see just how dangerous acid rain is. If it really is dangerous, I was also interested to see what thing's people can do to help stop its effects. If we cannot stop the effects, I would atleast like to know something’s I can do to lessen the effects on our environment. What is acid rain?
Damage to the soil is one of the most serious effects of acid rain. TREES Acid rain and other pollutants can have harmful effects on forests and many areas of the world have reported that their forests are dying. The acid takes important minerals away from the leaves and the soil. Without these minerals, trees and plants cannot grow pro... ... middle of paper ... ...every 2 to 5 years and it is expensive. Liming will not solve the problem of acid rain, to do that we must cut down on the amount of sulphur dioxide and nitrogen oxides that are produced.
