Environmental pollution occurs when pollutants contaminate the natural surroundings. Pollution disturbs the balance of our ecosystems, affect our normal lifestyles and gives rise to human illnesses and global warming. Pollution has reached its peak due to the development and modernization in our lives.
Carbon dioxide is a good Essay on paper pollution of sunlight, but particularly restricts infrared Essay on paper pollution going back from earth to space. This produces the green souse effect; this prevents the drastic cooling of the earth during night. CIFS are lowering the average concentration of ozone in the stratosphere.
Under high energy ultra violet CIVIC radiation break them down and release chlorine atoms, which speed up the breakdown of ozone 03 into oxygen Smog is the contraction of the words smoke and fog, smog has been caused by water condensing on smoke particles, usually from burning coal. With the introduction of petroleum to replace coal economies in countries, photochemical smog has become predominant in many cities, which are located in sunny warm and dry climates with many motor vehicles.
The worst episodes of photochemical smog tend to occur in summer. Nitrogen Oxides Knox Nitrogen oxides form when fuels are burned at high temperatures. Your car and power plants that burn coal, oil, and natural gas are the major producers. They also help to form ozone and particulate matter.
Nitrogen dioxide is decomposed by sunlight into nitrogen monoxide and atomic oxygen, which in-turn combines immediately with oxygen to form ozone The more sunlight available, the faster the reaction goes. Therefore, during summer in areas with high traffic, concentrations will increase.
Many of the deaths and illnesses result from pollution levels far below legislated targets, the study says, especially in the case of nitrogen dioxide NONmuch of it from car exhaust.
Saunders The health of our lungs and entire respiratory system is affected by the quality of the air we breathe. In addition to oxygen, this air contains other substances such as pollutants, which can be harmful.
Exposure to chemicals y inhalation can negatively affect our lungs and other organs in the body. The respiratory system is particularly sensitive to air pollutants because much of it is made up of exposed membrane.
Lungs are anatomically structured to bring large quantities of air on average, million liters in a lifetime into intimate contact with the blood system, to facilitate the delivery of oxygen. Eng tissue cells can be injured directly by air pollutants such as ozone, metals and free radicals.
Ozone can damage the alveoli the individual air sacs in the lung where oxygen and carbon dioxide are exchanged. More specifically, airway tissues which are rich in vaccinations enzymes can transform organic pollutants into reactive metabolites and cause secondary lung injury. Lung tissue has an abundant blood supply that can carry toxic substances and their metabolites to distant organs.
In response to toxic insult, lung cells also release a variety of potent chemical mediators that may critically affect the function of other organs such as those of the cardiovascular system. This response may also cause lung inflammation and impair lung function.
Air Pollution Causes Chronic Obstructive pulmonary Disease COP — is also known as chronic obstructive lung disease and encompasses two major disorders: Emphysema is a chronic disorder in which the walls and elasticity of the alveoli are damaged.
Chronic bronchitis is characterized by inflammation of the cells lining the inside of bronchi, which increases the risk of infection and obstructs airflow in and out of the lung.
Symptoms include cough, production of mucous and shortness of breath. It is important to note that no cure exists for people suffering from COP although healthy lifestyle and appropriate medication can help.
Ways to Stop Air Pollution Pollution is the introduction of a contaminant into the environment. It is created mostly by human actions, but can also be a result of natural disasters. Pollution has a detrimental effect on any living organism in an environment, making it virtually impossible to sustain life.
Human beings are the main cause of air pollution and we can take actions to stop pollution. Automobiles are the leading cause of air pollution, it is very important that we limit the amount of vehicles on the road. Carpool offers a good solution to limit car emissions by sharing rides with friends and coworkers.
A carpool journey — Saving energy: People waste energy so Oil, coal and other resources which pollute the environment are used. We have to turn off lights, fans, air conditioners, televisions and other electrical appliances when we are not using them.

Pulp and paper generates the third largest amount of industrial air, water, and land emissions in Canada and the sixth largest in the United States.
Professor Ouwehand English / MW Research Paper 16 April Essay III How Plastic Pollution is Out of Control Many individuals underestimate the amount of plastic we use each day. According to the article “Plastic Bags Wars”, “the world consumes 1 million plastic shopping bags every minute”. Air Pollution Causing Global Warming This paper presents the causes and effects of air pollution.
Natural air pollution has been around for millions of year. Air pollution is a major factor in causing humans to get ill. 3/5(10).
