	Air Pollution K-12 Experiments for Lesson Plans & Science Fair Projects
		Air pollution is a broad term applied to all physical (particulate matter), chemical, and biological agents that modify the natural characteristics of the atmosphere.
		A primary air pollutant is one that is emitted directly to the air from a given source, such as the Carbon monoxide (CO) produced as a byproduct of combustion; whereas a secondary air pollutant is formed in the atmosphere through chemical reactions involving primary air pollutants.
		The worst single incident of air pollution to occur in the United States of America occurred in Donora, Pennsylvania in late October, 1948, when 20 people died and over 7,000 were injured.

	Air pollution in British Columbia - Wikipedia, the free encyclopedia
		Air pollution is a concern in British Columbia (BC), Canada because of its effects on health and visibility.
		Air quality is influenced in BC by numerous mountain ranges and valleys, which complicate atmospheric pollution dispersion and can lead to high concentrations of pollutants such as particulate matter from wood smoke (especially during stangant atmospheric conditions/ inversions).
		The health effects of air pollution vary with the size and characteristics of the exposed population, the specific pollutant or mix of pollutants and the concentration of pollutants, both in the short term and the long term.

	Air Pollution - Health Effects
		Air pollution is a less significant source of hazardous environmental chemicals in the gastrointestinal (GI) tract than is the ingestion of contaminated food and water (which may have been contaminated by air pollution).
		Air pollution correlates with increased prevalence of chronic cough, chest illness, bronchitis, hospital admissions for respiratory conditions, and decrements in lung function.
		Aging individuals are more susceptible to air pollution because of the declining margin of safety in various organ systems, including the respiratory and immune systems, and because, in some cases, of the cumulative effect of environmental hazards.

	Air Pollution, Environment, Health, Disease; Chemical Toxicity
		Air pollution, both indoor and outdoor, is a significant cause of health problems worldwide.
		There are five obvious sources of air pollution - the burning of fossil fuels, the cutting of forests and burning of slash, the increasing use of agricultural and industrial chemicals, the continued smoking of tobacco products, the creation if indoor work and living environments which concentrate air contaminants and create "sick buildings."
		A decrease in indoor air quality is the result of reduced ventilation and efficient construction practices, sealing homes and office buildings from the outdoor environment.

		Air Pollutants are any gas, liquid or solid substances that are present in the atmosphere in high enough concentrations to be considered harmful to the environment or human health.
		Air Emissions are any kind of substance released into the air from natural or human sources.An emission inventory provides information on the amount of emissions coming from various sources in a given area within a given period of time (usually a year).
		Concentration is the amount of a pollutant in the air at a given location, expressed as the weight of volume of pollutant per volume of air, such as parts per billion (ppb) or micrograms per cubic metre of air (µg/m3).

	David Suzuki Foundation: Climate Change : Air Pollution
		Burning fossil fuels is the main cause of both air pollution and climate change, and health experts have concluded that climate change will actually make air pollution an even greater health threat - unless fossil fuel emissions are drastically reduced.
		Air pollution from burning fossil fuels produces many other compounds that hurt our health: carbon monoxide, nitrogen oxide, sulphur dioxide, volatile organic compounds, and small airborne particulates.
		Air pollution is also the primary culprit behind rising levels of asthma.

	International Journal of Health Geographics \| Full text \| Opportunities for using spatial property assessment data in ...
		A major constraint to moving toward exposure assessments and epidemiological studies of air pollution at a neighbourhood level is the lack of readily available data at appropriate spatial resolutions.
		For example, land use regression (LUR) models have been used to predict traffic-related air pollution levels for neighbourhood areas depending on nearby roads, traffic volume, population density, and land uses [3-5]; these predicted levels were then used as indicators of exposure for epidemiological analyses.
		An example of this approach, employed for eight regions in British Columbia, is described in a recent report produced by the British Columbia Ministry of Water, Land and Air Protection [10].

		Perhaps you are also familiar with the term "Greenhouse effect." Because those two terms are so important in understanding the pollution problem associated with burning biomass and fossil fuels, we should touch upon their definitions now.
		Scientists believe that global warming is caused by the "Greenhouse effect." The greenhouse effect describes the accumulation of carbon dioxide in our earth's atmosphere.
		But as humans began to burn fossil fuels to create energy (especially beginning just before the 20th century during the "Industrial Revolution"), more and more carbon dioxide was emitted into the air until the balance was slowly destroyed.
