	Pollution
		The effect of pollution events on the environment depends on their severity, ranging from minor and localised effects to complete devastation for a number of years.
		Pollution incidents, which can affect water, air and land, are described in terms of their impact.
		Pollution incidents in England and Wales are investigated by the Environment Agency.

	Chile: Environmental Issues (Site not responding. Last check: 2007-10-30)
		The pollution problem is further exacerbated in winter when wind and rainfall levels are at their seasonal lowest.
		Besides geography and weather, air pollution in Santiago is a result of both mobile and fixed sources, a growing economy, rapid urban expansion and an increasing rate of automobile use.
		With total energy demand expected to continue to grow by 7% annually, and air pollution in Santiago already reaching critical levels, the continuing evolution of Chile's fuel mix away from petroleum and coal and towards natural gas and hydroelectric generation is key to the country's environmental future.

	Math Forum - Ask Dr. Math
		Suppose that pollution at a particular location is based on the distance from the source of the pollution according to the principle that for distances greater than or equal to 1 mile, the concentration of a particular matter (in parts per million, ppm) decreases as the reciprocal of the distance from the source.
		The total pollution at your residence will be the sum of these two individual pollutions, so the total pollution at your residence will be: 60/x + 240/(10-x) But this formula is only good for values of x between 1 and 9.
		But as you get closer to the 240-ppm, the amount of pollution from the 60-ppm plant is going down (because you're moving away from it.) Notice that if you pick x = 9, you're getting a maximum amount of ppm from the 240-ppm plant and that you're getting 60/9 ppm from the 60-ppm plant.

	Water Pollution
		Pollution of lakes rivers, streams, and oceans has been killing land and water animals for years.
		When you dump in a stream the pollution will eventually coat all the plants and trees and kill bugs, and other animals then it leaks into a lake and spreads out making the lake or river not tolerable to anything at all.
		Millions of animals are killed by water pollution not to mention the 10,000,000 people who die each year from drinking polluted water.

	Puget Sound Clean Air Agency - What is an Inversion?
		The result is the same: we are unable to rid ourselves of the everyday pollution that we create.
		This means that air is mixing and that air pollution is able to rise and be dispersed.
		In this graph, the temperature initially is increasing with altitude.

	Setting the Optimum Carbon Tax Level: a graph
		This graph represents the economic effect of a carbon tax and shows how the tax level might best be set.
		The graph promotes the idea that the tax would be most efficient if set at a level that would reflect the marginal cost of abatement as well as the marginal damage costs of pollution.
		When a carbon tax is introduced, emissions are reduced to the level at which the cost of abating emissions and the cost of paying the levy on emissions are at an equilibrium.

		To investigate locational differences in mean kerbside pollution levels and assess their relationship to the configuration of the fine scale street grid in urban neighbourhoods.
		The graph on the left shows a comparison of various percentile values for 3 roads the windward axis is when the monitoring point was on the windward side of the road the other axis represents all other wind directions.
		The fine scale pollution model is based on a representation of the configuration of urban space represented in terms of the main linear elements of the street grid.

		We measure the concentration of these pollutants, then we add up the number of days in each year when any of these four pollutants is classed as 'low', 'moderate', 'high' or 'very high' according to standards set by the Government.
		The increase in 1999 may have been primarily due to the adverse weather conditions of 1998 preventing ozone from being formed as readily as it was in 1999, with the weather conditions in 2000 also preventing ozone being readily formed.
		Information on air pollution in your area is available on the Herts and Beds Air Pollution Network website.

	Air Pollution — City Comparisons
		However, this it is interesting to see that although some cities general air pollution levels can be quite low, levels of particular individual pollutants such as particle matter or nitrogen oxides can be high and therefore still cause severe health problems to the population.
		The reasons for such varying pollutant levels from city to city is due to a number of reasons be they natural or man made.
		This graph show clearly that West London and Edinburgh have considerably higher levels of nitrogen dioxide than Belfast and Cardiff but even these relatively high results are low in comparison to results in the past and indeed are still falling to this day, as the graph indicates.

	NRDC: Healthy Milk, Healthy Baby - The Chemicals, One by One
		Despite the shortcomings of research on pollution in breast milk, scientists have detected many different pesticides in breast milk throughout the world.
		One of the things that scientists have learned about the persistent organic pollutant contaminants in breast milk -- chemicals such as dioxins, PCBs, PBDEs and the organochlorine pesticides -- is that the levels in breast milk tend to be higher in first-time mothers and also tend to be higher during the early months of breastfeeding.
		Mothers who breastfeed for a long period of time, or who nurse more than one child, can have lower concentrations of pollutants in their breast milk than mothers who breastfeed for shorter periods of time, or who breastfeed only one child.

	Ocean Planet: Oil Pollution
		Only about 5 percent of oil pollution in oceans is due to major tanker accidents, but one big spill can disrupt sea and shore life for miles §.
		MARPOL (for MARine POLlution) is shorthand for a United Nations treaty (the Convention for the Prevention of Pollution from Ships) that became effective in 1983.
		MARPOL is largely credited for reducing oil pollution from shipping by about 60 percent worldwide during the 1980s §.

	[ Types: Thermal Pollution ]
		Heat produced from industries is a major contribution to the pollution, much to the operation of the heavy industries which produces high amount of heat energy.
		Measurements of atmospheric temperature are done by meteorological center of the weather forecast annually, and the graph to detect the temperature trend from a period of 10 years will be compared with the previous batch of period.
		Thus we may be able to know the rate of temperature increase overall and make reference to the standard level of heat that should be maintain in the atmosphere to avoid large deviation of heat in the system.

	Top Story - NASA SENSORS FIND POLLUTION HIDING IN THE SHADOZ - May 31, 2002
		This graphic shows how the pollution is moving with easterly winds blowing from South America pushing pollution into the middle Atlantic, and westerly winds from Africa also blowing pollution into the mid-Atlantic, where atmospheric motions are already dumping ozone.
		This motion brings pollution from the Pacific Ocean, and also deposits it over the Atlantic, adding to the "pile up." Both pollution and the pileup are strongest between August and November.
		NASA and scientists from 10 tropical countries have used balloon-borne sensors to obtain the first picture of the structure of ozone (pollution) in the tropical troposphere, the atmospheric layer between the surface and 50,000 feet.

	Muddying the air
		One would think that the reduction in lead pollution in particular, which Lomborg considers to be a significant problem (see Getting the lead out), is a success of environmental regulation.
		These events would be expected to increase pollution levels if the were not offset by changes in pollution control.
		While other events, such as weather patterns that trapped the pollutants, played a part in these disasters, it is hard to see how these smogs could have occurred if pollutant levels had been dropping for seventy years as Lomborg's graph shows.

		Also, in addition to the effects of air pollution via the soil, the programme stresses the increasing importance of the effects of ozone gas on needles and leaves.
		Scientists under the Convention’s programme are well aware of the need for further cuts in air pollutants to address the remaining air pollution problems, including those of human health.
		Scientific evidence of air pollution effects on vegetation, freshwaters, materials and human health has been the driving force of air pollution abatement policies under the Convention since its adoption in 1979.

		The graph given below shows the percentage of water pollution events dealt with by SEPA which are caused by oil.
		The graph shows that there has been little change in the percentage of pollution events resulting from oil since 1999/2000, with oil accounting for around 20% of all incidents.
		Studies of oil pollution events have shown that it is often very difficult to identify the source and the cause of the event.

	Chapter 100-: Trade Policies with Market Imperfections and Distortions
		In other words, the greater the consumption of gasoline, the greater is the pollution and the greater is the subsequent harm caused to people in the country.
		In this case, environmental pollution caused by the consumption of gasoline is a market imperfection because gasoline consumption has a negative external effect (via pollution) on others within the society.
		It may be relatively easy to measure the average amount of pollutants (carbon dioxide, sulfur, etc.) caused by each gallon of gasoline consumed, but translating that into a dollar equivalent is not a simple task.

	Children's report card: Air pollutants
		Air pollution imposes environmental costs through such things as acid rain and toxic exposure for aquatic life and economic costs mainly in the form of public health expenditures and regulatory costs.
		The Minnesota Pollution Control Agency's regulation of large industrial sources of air pollution has contributed to large improvements in air quality in the last two decades.
		Since many of these pollutants come from cars, trucks, buses, airplanes and power plants, protection of air quality involves reducing fuel and energy consumption, adopting cleaner fuels and shifting to other technologies that reduce air pollution, such as fuel cells.

	eMJA: Wealth, poverty and climate change
		This issue is illustrated starkly by a graph developed from calculations by Hughes at the University of Edinburgh3 (Box).
		It shows the ratio of the cost of health and economic damage from local energy-derived air pollution (household indoor pollution from use of poor quality fuels and urban outdoor air pollution) to the cost of damage from climate change.
		The graph shows that, in poor countries, short-term local pollution typically causes three to four times more health and economic damage than climate change.

		These thoughts got me thinking about air pollution in the U.S.A. This prompted me to create a lab and research paper for my classroom to bring awareness to my students of the duty that each of us has to keep our environment clean.
		During the three day wait the students will be doing research on air pollution in our library and on their own.
		It will be of particular interest to see the students trying to figure out where the pollution sources are and to discuss how easily things could be changed in order to reduce pollution levels.

	Gasoline - Wikipedia, the free encyclopedia
		Though relaxed volatility standards damage ozone and pollute the air, higher volatility gasoline (which contains less additives than gasoline whose volatility has been artificially lowered) effectively increases a nation's gasoline supply by making it easier for oil refiners to produce gasoline.
		Gasoline is also one of the sources of pollutant gases.
		Even gasoline which does not contain lead or sulfur compounds produces carbon dioxide, nitrogen oxides, and carbon monoxide in the exhaust of the engine which is running on it.
