Question 1: indoor air pollutants that are hazardous to health

Answer:

are chloroform, benzene, carbon tetrachloride, formaldehyde, syrene, biohazards (i.e. mold, pathogens), and cigarette smoke

Question 2: ambient air

Answer:

the air around us

Question 3: point source

Answer:

smokestack or some other concentrated pollution origin

Question 4: Primary pollutants

Answer:

are released in aa harmful form

Question 5: ozone hole

Answer:

Chemical reactions of atmospheric gases and pollution produce the phenomenon

Question 6: Fugitive or nonpoint-source

Answer:

emissions are those that do not go through a smokestack.

Question 7: albedo

Answer:

the proportion of the incident light or radiation that is reflected by a surface, typically that of a planet or moon.concrete and brick surfaces in cities absorb large amounts of solar energy

Question 8: organic compounds have decreased the least

Answer:

Nitrogen dioxides, particulate matter, ozone, and volatile

Question 9: Secondary pollutants

Answer:

hazardous after reactions in the air.

Question 10: dust dome.

Answer:

Tall buildings create convective updrafts that sweep pollutants into the air. Stable air masses created by this heat island over the city concentrate pollutants

Question 11: unconventional pollutants (def)

Answer:

compounds that are produced in less volume than conventional pollutants, but that are especially toxic or hazardous.

Question 12: conventional or criteria pollutants (6)

Answer:

sulfur dioxide, nitrogen oxides, carbon monoxide, ozone (and its precursor volatile organic compounds), lead, and particulate matter.

Question 13: Greenhouse Gases

Answer:

Carbon Dioxide and Halogens methane, nitrous, oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride.

Question 14: Ozone (O3)

Answer:

ground level ozone is highly reactive oxidizing agent that damages eyes, lungs, and plant tissues, as well as paint, rubber, and plastics. It is a secondary pollutant, created by chemical reactions that are initiated by solar energy

Question 15: stratospheric ozone is being destroyed by

Answer:

primarily chlorine-based aerosols, including chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) (p. 239).Question 16: additional hazardous air toxins added to the list regulated by the Clean Air Act

Answer:

are asbestos, benzene, mercury, polychlorinated biphenyls (PCBs), and vinyl chloride

Question 17: Stratospheric ozone

Answer:

naturally-occurring gas that filters sun's (UV) radiation. This is typically regarded as 'good' ozone since it reduces the harmful effects of ultraviolet (UV-B) radiation. A diminished ozone layer allows more radiation to reach the Earth's surface.

Question 18: dominant sources of most criteria pollutants (2)

Answer:

Transportation and power plants

Question 19: Anthropogenic

Answer:

(chiefly of environmental pollution and pollutants) originating in human activity.

Question 20: how Air pollutants can travel

Answer:

Dust and fine aerosols can be carried great distances by the wind

Question 21: Physical effects of pollutants

Answer:

irritate our eyes and lungs, enter our blood stream when we breathe them, then damage nerves and brain function.

Question 22: the clean air act saved costs

Answer:

The mainly saved costs are from reduced illness and property damage with an increase in productivity

Question 23: temperature inversions

Answer:

reverses the normal conditions.occur where ground-level air cools more quickly than upper air. With cold air resting below the warmer air, there is little mixing, and pollutants are trapped near the ground.

Question 24: Montreal Protocol,

Answer:

In 1987 an international meeting in Montreal, Canada, produced , the first of several major international agreements on phasing out most uses of CFCs by 2000.

Question 25: Health Effects of Air Pollution

Answer:

Consequences of breathing dirty air include: increased probability of heart attacks, respiratory diseases, and lung cancer.

Question 26: The Clean Air Act (1970) purpose

Answer:

designated new air quality standards, to be applied equally across the country, for six major pollutants.
