Essay On Sulfur Dioxide In Environment

Air pollutants don’t only affect humans, but also majorly harm our ecological resources such as- soil, plants, animals, and water. Nitrogen and sulfur in air pollution are carried by rain, snow, and mist into environments where they affect sensitive aquatic and terrestrial resources.

Air pollution situation is created by the release of pollutants into the air .These substances are detrimental to human health and the planet as a whole. When air becomes contaminated or polluted, it becomes hazard to humankind and other living species on the earth. The use of energy and different forms of gaseous emissions is the reason for air pollution. According to John Walke, director of the Clean Air Project, part of the Climate and Clean Air program at NRDC. “Burning fossil fuels releases gases and chemicals into the air.” Air pollutants are identified as an indicator of air quality are nitrogen oxides (NO2), sulphur oxides (SO2), carbon monoxides (CO), ozone (O3), particulate matter (PM10) and lead (Pb). SO2, NO2, CO and PM10. These are well recognized as sources emitted from the combustion of fuels used in power and desalination plants (Brunekreef, B., & Holgate, S. T.,2002).

Smog is highly prevalent in the most contaminated area embodying sulfur dioxide pollutants - Pekin, IL. With this, the DangerInTheAir studies fully demonstrate defected areas emitting heavy sulfur dioxide pollutants as definite factors to prolonging asthma related health issues.

There are two main types of air pollution, particulate matter (PM) and ozone. Particulate matter is some tiny dust. For example, according to a beam of light at night there are countless dusts floating in the air. They are particle. Ozone is an invisible chemical gas in the air. When these gas touch with light will become smog. Factory and vehicles exhaust emissions have become the largest cause of PM and ozone pollution in the United States. If a plant wants to run, they need to burn fuel to provide power; however, a lot of particulate matter will float in the air when the factory burns fuel. When people drive cars can

This article relates to Week 3 Lecture about Physical and Social Environment, which describes the terrible smell, which is hydrogen sulfide has an indoor and outdoor pollutant. As an indoor pollutant, the smell enters people’s homes through their toilets. As an outdoor pollutant, sewers lines were poorly designed leading to the release of hydrogen sulfide. Hydrogen sulfide as an indoor and outdoor pollutant is detrimental to people’s health because people are exposed to the gas by breathing in the air from all areas. The article relates to the community level of the ecological model. In the article, the city installed carbon air filters and sealed the manhole covers as they continue to monitor the levels of sulfide in the air. This shows that the Plano officials are concerned about the effects of the hydrogen sulfide and the long-term effects it could have on people. The air can cause serious respiratory problems such as asthma and

While the mechanisms are poorly understood many scientists are suggesting the interaction of sunlight with air pollutants creates a cascade of reactive species which increase the amount of air pollutants as well as their potency3. For example, sulfur dioxide and particulate matter emissions from a coal-fired power plant may react in air to produce acid sulfates and aerosols which are highly penetrable to the airways and travel long distances before settling.

Exposure to pollutants such as C02, results in negative effects to the human health and to the environments wellbeing. For example, in America 25 million people suffer from asthma attacks and unfortunately that is responsible for 3000 deaths each year (Asthma and Air Pollution, 2014). Though it has no cure, reducing air pollution from cars, factories, and refineries can ease the risk of having an asthma attack. Not only does CO2 affect humans but the environment as well, mainly the aquatic ecosystem because of acid rain and eutrophication from the built up CO2 (Air Quality, 2014). Fish and plants are unable to survive in acidic water and eventually die. The food chain is effected causing additional death. Once the animals perish, humans are bound to be

Medline-plus states that “some air Pollutants are poisonous to us”, I agree with them because us humans are destroying air with fuel, factories, and even cars, we just don’t seem to care much for the earth we live on. Since we are contaminating air with chemicals and diseases and other stuff that can harm the earth the oxygen levels have decreased since the 1990. In the 90’s there was 21% oxygen level it has decreased over the last 20 years to 19%, although that might not look like a big deal but it is because if we keep decreasing the oxygen level we might not even have oxygen by the time the 22 century comes

Since the Industrial Revolution, there has been an increased presence of pollutants and carcinogens in the environment, specif-ically in urban areas.1 The presence of airborne pollutants can lead to an increase in allergic reactions and asthma rates. A common airborne pollutant is carbon monoxide (CO), which is commonly found in diesel exhaust. It is an odorless gas produced from me-thane and non-methane hydrocarbon oxidation.2 The toxic gas eliminates and takes the place of oxygen in the form of carboxy-hemoglobin when it binds to hemoglobin in red blood cells. It also affects the binding sites of heme groups, which complicates the transfer of oxygen to tissues.3 The majority of deaths from carbon monoxide poisoning is brought on from car exhaust.4 Between the years 1979 and 1988, 57% of deaths from carbon monoxide poi-soning were brought from car exhaust. There tend to be higher rates of carbon monoxide poisoning from car exhaust in northern regions, where temperatures are relatively low (Figure 1). 5

The population on Earth is expanding rapidly which goes hand in hand in the degradation of the environment at large measures. The human’s appetites for needs are disarranging the environments natural equilibrium. Our production industries are venting smoke and discharging chemicals that are polluting our water. The smoke that is emitted into the atmosphere holds unappealing gases such as carbon monoxide and sulfur dioxide. The high

The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases –– primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed. Although uncertainty exists about exactly how earth’’s climate responds to these gases, global temperatures are rising. Go to the Emissions section for much more on greenhouse gases.

Other pollutant from cars was lead; it is highly toxic metal. Lead has been phased out of gasoline, but there, are other sources of it. It includes paints, production of lead batteries, water pipes, and a few heir dye products. Car exhausts can also produce nitrogen oxide, volatile organic compounds, which are also, product of burning fuels. Factories and power plants produce same pollutants as cars do, but they produce them in bigger mnozstve and the produce some more such as sulfur dioxide, which is made during production of paper, burning coal in power plants, or smelting of metal. Burning other fuels like wood, or natural gas can make all of these pollutants too.

In today’s society chemicals, whether you like it or not are a fact of life. Many people are afraid of chemicals and their effects on them and the environment. This is understandable because the truth of the matter is that chemicals can do some horrible things to humans, animals and the whole ecosystem. Some would say that chemicals should be done away with for these reasons. But this certainly is not true and most likely impossible. Chemicals can also have some very positive effects on our lives. Some uneducated people would argue that there should not be restrictions on chemicals. This is just as crazy as saying that chemicals should be done away with. If chemicals are regulated and people abide

Automobiles are undeniable the greatest source of pollution. The noise pollution created by cars is immense. Another polluting effect of cars is the heat it creates. This heat makes it unpleasant to be near the car while its running. And of course the most famous

Sulphur dioxide is identified to be toxic when it has be breathed in and may cause burns and irritations to the eyes and respiratory system due to the accumulation of fluid in the lungs. It is concluded that about 99% of the sulphur dioxide in air comes from human sources and the main source is industrial activities. Sulphur dioxide is a choking gas and may trigger an asthma attack (even some hours after exposure). South Durban has several petrochemical refineries and chemical industries and with its topography of a basin- like shape. The structure aids with the accumulation of Sulphur dioxide in the air, resulting in and this has been an ongoing concern for South Durban since the 1980. There was no excess incidence of respiratory
