Air Pollution (Endangered Global Commons)

Natural Air Pollutants Volcanoes sulfur oxides, particulates Forest Fires Carbon monoxides, carbon dioxide, Nitrogen oxides, particulates Wind storms Dust Living Plants Hydrocarbons, pollen Decaying plants Methane, hydrogen sulfide Sea Salt particulates

Major Air Pollutants

Carbon Monoxide From transportation Causes headache, dizziness, decreased tolerance to exercise
Sulfur oxides Coal fired power plants Asthma, bronchitis industry

Nitrogen Oxides Transportation, Coal fired lung irritation, bronchitis Power plants

Particulates Coal fired power plants Irritation of respiratory tract, cancer Industry

Hydrocarbons Transportation Unknown

Photochemical
Oxidants Transportation, coal fired Respiratory irritation, emphysems Power plants, industry

Components of fossil fuel Hydrocarbons when incompletely burned form: carbon monoxide, unburned hydrocarbons and water Hydrocarbons when completely burned form: carbon dioxide and water

Contaminants: sulfur---(heated)---Sulfur dioxide and sulfur trioxide

Mineral contaminant---(heated)…Particulates (e.g. lead and mercury)

Nitrogen gas----(heated)…Nitric oxide and nitrogen dioxide

Many of the pollutants react with solar energy and water to produce secondary pollutants, for example sulfur dioxide and water form sulfuric acid.

Photochemical smog- unburned hydrocarbons and nitrogen oxides from power plants and automobiles react with sunlight to form secondary pollutants: ozone, formaldehyde, PAN. Ozone erodes rubber, irritates the respiratory system and damages plants.

Temperature inversion

Cleaner air Bag filter at electric power plants remove particulates Cyclone collector particulate removal- used in smaller industry Electrostatic precipitator removal of particulates at coal fired electric plants Spray collector, also called

    Air Quality - 1

    • 1412 Words
    • 6 Pages

    Air quality is a measure of the amount of pollutants emitted into the atmosphere and the dispersion potential of an area to dilute those pollutants. It is a massive problem of urban living and remains one of the largest environmental concerns. Spatial dimension relates to how air quality differs between places at different times and under different weather patterns. Increasing population and demand for more goods puts greater pressure on air quality. The human population’s interaction with the environment relates to the ecological dimension. In terms of air quality this relates to the impacts of increased gases and particles associated with transportation, industrial activities, smoking, dust storms from over grazing on marginal land, bush fires and the burning fossil fuels . Many of these activities cause increases in carbon monoxide, ozone, sulphur dioxide, nitrogen dioxide, lead and particles in the atmosphere. People get health problems due to these increases. For example, excessive carbon monoxide levels in the blood stream reduce its ability to transport oxygen. This in turn causes headaches and tiredness.…

    Some other primary pollutants are hydrocarbons such as benzene, toluene and naphthalene are released to the atmosphere due to the oil evaporating from the water. While they are cleaning up the pollutants in the water, the air pollution happens do the soot and very large particles that float in the air and releases of NOx (generic term for mono-nitrogen oxides) which reacts to form ozone layer and turning into smog. These aerosols, soot and NOx (mono-nitrogen oxides) react with compounds in the atmosphere and sunlight and produces secondary pollutants like peroxyacetyl nitrate and ozone (O3) which are harmful to one’s health.…

    Anthropogenic Effects

    There are many different types of anthropogenic toxins in the world. About two percent of deaths annually are in the United States because of air pollution. Anthropogenic pollution is most prevalent in urbanized regions, which include North America, Asia, and Europe. Some of the specific types of anthropogenic pollutants are carbon monoxide, nitrogen oxide, sulfur dioxide, volatile organic compounds, and particulate matter. Carbon monoxide is very harmful to the environment. It is made by the incomplete combustion of fuels or other carbon-containing substances. Different types of transportation make Ten percent of all carbon monoxide. A large source of carbon monoxide was found in south-central Africa and the Amazon region of South America because of the mass burning of biomass. Nitrogen oxide is another form of toxin. High temperatures and pressure combustion produces the pollutant known as nitrogen oxide. North American urban areas have ten to a hundred times higher nitrogen dioxide concentrations that nonurban areas. Nitrogen dioxide combined with other gases can for harmful substances. It can produce nitric acid, ozone pollution, and photochemical smog. Another pollutant from the automobile is photochemical smog. This pollutant results from the interaction of sunlight and combustion products in automobile exhaust.…
