Ch 17 Air Pollution

Front 1

lichens

Back 1

fungus and an algae living together in a mutualistic partnership, good air pollution detectors b/c they always absorb air, certain species are sensetive to specific air-polluting chemicals, can help track pollution to its source

Front 2

troposphere

Back 2

atmosphere's innermost laer, thin and turbulent, weather breeder

Front 3

stratosphere

Back 3

second layer, less matter but similar composition of troposphere except volume of water vapor is about 1/1000 and concentration of ozone is way higher

Front 4

stratospheric ozone

Back 4

produced when some oxyegen molecules interact with UV radiation, the UV filter allow humans to exist on land, prevent from sun damage, and prevent oxygen being converted to a harmful air pollutant

Front 5

air pollution

Back 5

presence of chemicals that cause harm or alter the climate

Front 6

natural sources of pollution

Back 6

dust, SPMs, sulfur oxides, carbon oxids, nitrogen oxides, hydrocarbons and pollen, methane and hydrogen sulfide, and salt particulates

Front 7

primary pollutants

Back 7

those emmitted into troposphere in potentially harmful form

Front 8

seondary pollutants

Back 8

when primary pollutants are in the tropsophere and react with one another to form new pollutants

Front 9

amt of people that live in urban areas where air is unhealthy to breathe

Back 9

1.1 billion

Front 10

Big 6 criteria air pollutants

Back 10

carbon monoxide, nitrogen dioxide, sulfur dioxide, suspended particulate matter, ozone, lead

Front 11

carbon monoxide

Back 11

cigarette smoking, incomplete burning of fossil fuels- reduces the ability of blood to bring oxygen to body cells and tissues

Front 12

nitrogen dioxide

Back 12

gives photocemical smog its brownish color, fossil fuel burning in motor vehicles, lung irritation and damage

Front 13

sulfur dioxide

Back 13

coal burning in power plants, breathing problems, reduces visibility

Front 14

SPM

Back 14

variety of particles and droplets, cause smoke, dust, and haze- burning coal in power plants,nose and throat irritation

Front 15

ozone

Back 15

breathing problems can damage plants and trees

Front 16

lead

Back 16

paint, leaded gasoline- causes brain and other nervous system damage, can harm wildlife

Front 17

photochemical smog

Back 17

mixture of primary and secondary pollutants formed under sunlight; nitrogen and oxygen react to produce nitric oxide. nitric oxide reacts to form nitrogen dioxide

Front 18

industrial smog

Back 18

consisting mostly of sulgur dioxide, SPMs

Front 19

factors that influence frequency and severity of smog

Back 19

locl climate and topography, population density, smount o industry, and fuels used

Front 20

factors that reduce air pollution

Back 20

rain and snow and winds

Front 21

factors that increase air pollution

Back 21

urban buildings, hills and mountains, and high temperatures

Front 22

subsidence temperature inverson

Back 22

occurs when a large mass of warm air moves into a region at a high altitude and floats over a mass of colder air near the ground, prevents verticasl mixing and dispersion of air pollutants

Front 23

radiation temperature inversion

Back 23

occurs at night as air near the ground cools faster than the air above , usually disappears by noon and dispereses pollution built up during night
