APES Unit 7 Study

Dust and soot are examples of this type of pollutant

Particulate Matter

Photochemical smog forms when primary pollutants and secondary pollutants react in the presence of this.

Sunlight

These two pollutants contribute the most to acid deposition

nitrogen oxides and sulfur dioxide

This occurs when a layer of warm air traps cooler air below it and commonly occurs in this west coast city

thermal inversion of Los Angeles

The pollutants commonly targeted by electrostatic precipitators and scrubbers respectively

particulate matter, and sulfur oxides

This pollutant reduces the bloods ability to carry oxygen, causing headaches, dizziness, and even death

carbon monoxide

Furniture stuffing, paneling, and foam insulation are all sources of this pollutant

Formaldehyde

The four most dangerous indoor air pollutants according to the EPA.

asbestos, radon, cigarette smoke, and formaldehyde

The criteria for determining if a building is sick

20%1 or more people complaining of symptoms such as headaches, nausea, fatigue, and coughing2 while in a building3 but feeling better when they leave4

This pollutant comes from the radioactive decay of uranium and its remediation technique

radon and proper ventilation

The layer of the atmosphere that contains this helpful ozone

the stratosphere

The thinning of the ozone layer is occurring primarily over this continent at this time of year

Antarctica in October/spring

Much of the ozone thinning has been caused by this chemical and specifically this element

chlorofluorocarbons (CFCs) and the chlorine molecule

Less ozone means increased exposure to this radiation which causes

UVB radiation which causes skin cancer

The first meeting to reduce CFC emissions was held in this location and established this agreement

Montreal and the Montreal Protocol

The most abundant and variable nonanthropogenic greenhouse gas

water vapor

The percent increase in carbon dioxide from 283 ppm in 1790 to 383 ppm in 2007

30-38%

The greenhouse gas that is a product of anaerobic respiration, livestock gas, and landfills

Methane

This makes a greenhouse gas more potent than CO2

GHG's ability to absorb more heat energy

The type of radiation that is absorbed by Earth's surfaces that is re-emitted as this type of radiation

visible light and infrared

The region of Earth that will experience the most significant changes in temperature as warming continues

the poles

A possible effect of the rapid ice loss in the arctic is the shutdown of this process because of the inundation of melting freshwater

the oceanic conveyor belt

Since 1900, the Earth's temperature has risen by about this amount

0.6-0.8°C? (1°C or 1.5°F is acceptable)

The reason that the melting of Earth's ice (glaciers, ice sheets, ice caps) will cause to the further increase in Earth's temperature

the lower albedeo of water compared to ice

The reason that infectious tropical diseases are likely to spread to higher latitudes as Earth's average temperature increases

rising temperatures allow disease-carrying mosquitoes to move into new areas
