Discussion #2: Air Quality

As you already know, we need to deal with air pollution in order to address global warming! I created a comparison chart to examine Ozone, Sulphur Dioxide, Nitrogen Dioxide, Total reduced sulphur compounds, Carbon monoxide, and Fine particulate matter.

As you can see in the chart, there are sources and impacts of the various problems of air quality:

Air Problem Source Impact
Ozone -The concentration of ozone in the atmosphere (especially altitude before around 1km of the surface of the earth) is getting higher. -The emission gas from the car, which consists of nitrogen oxide (NOx) that provokes photosynthesis process by the strong ultraviolet energy. -Since ozone contains a matter that reacts stronger compared to the oxygen, it can stimulate the mucous membrane of lung or the skin. The high concentration of ozone can especially be fatal to an old or feeble person as well as an asthma patient.
Sulphur Dioxide -The emission from sulphur dioxide creates misty sky. The principal source is considered as the coal. Whenever the factory or the household burn the coal, it starts to belch up sulphur dioxide and the smoke. -It becomes a harsh pollutant and harms animals, plants, and human beings on a strong sunny day and especially when there is no wind.
Nitrogen Dioxide -The concentration of nitrogen dioxide increased by 40% ever since 1980. -It comes from car, truck, bus, powerhouse, industrial equipment, etc. -It has a huge impact on human’s health, specifically to children, asthma patient, and senior. It can also cause respiratory ailments.
Total reduced sulphur compounds -It generates offensive odours akin to rotten eggs or cabbage. -The sources are regarded as steel industry, pulp and paper mills, refineries, and sewage treatment facilities. Moreover, the natural sources are swamps, bogs, and marshes. -Total reduced sulphur compounds generally do not have impact on health, but each component differs from one another. It can cause nausea and headaches and if it is released into the atmosphere, it can contribute to the acidity of the environment, because of sulphuric acid it contains.
Carbon monoxide -Almost every matter while burning can release carbon monoxide. -It comes from any matter that is burnt, such as an exhaust pipe, a tobacco, an air conditioner, a radiator, etc. -If inhaled, it attaches to hemoglobin and may cause headache. If one is in airtight place, he or she can die due to an addiction of carbon monoxide.
Fine particulate matter -People are breathing air with fine particulate matter and that the atmosphere must be purified according to the experts. -It comes from a diesel combustion truck, a powerhouse, a heater that burns trees, and other pollution sources. -It can cause problems with the respiratory organs as well as the heart problem.

    Michelle, you state that we need to deal with air pollution in order to address global warming. But all the impact statements seem to address direct health issues instead of how that particular substance impacts global warming. For instance, how does ozone impact global warming?
