4078011730	air pollution	the introduction of chemicals, particulate matter, or microorganisms into the atmosphere at high concentrations high enough to harm plants, animals, and materials such as buildings, or to alter ecosystems	0
4078011731	particulate matter (PM)	solid or liquid particles suspended in air; also known as particles and particulates	1
4078011732	photochemical oxidants	a class of air pollutants formed as a result of sunlight acting on compounds such as nitrogen oxides	2
4078011733	smog	smoke and fog	3
4078011734	photochemical smog	smog dominated by oxidants such as ozone	4
4078011735	volatile organic compounds (VOCs)	an organic compound that evaporates at typical atmospheric temperatures	5
4078011736	primary pollutants	a polluting compound that comes directly out of the smokestack, exhaust pipe, or natural emission source	6
4078011737	Los Angeles-type smog	aka brown smog; a type of photochemical smog	7
4078011738	sulfurous smog	smog dominated by sulfur dioxide and sulfate compounds	8
4078011739	London-type smog	aka gray smog; a type of sulfurous smog	9
4078011740	secondary pollutants	a primary pollutant that has undergone transformation in the presence of sunlight, water, oxygen, or other compounds	10
4078011741	thermal inversion	a situation in which a relatively warm layer of air at mid altitude covers a layer of cold, dense air below	11
4078011742	Inversion layer	the layer of warm air that traps emissions in a thermal inversion	12
4078011743	chlorofluorocarbons (CFCs)	a family of organic compounds whose properties make them ideal for use in refrigeration and air conditioning	13
4078011744	asbestos	a long, thin fibrous silicate mineral with insulating properties, which can cause cancer when inhaled	14
4078011745	sick building syndrome	a buildup of toxic compounds and pollutants in an airtight space; seen in newer buildings with good insulation and tight seals against air leaks	15
