Environmental Health Air Quality Ch 10

Front 1

Smog

Back 1

smog denotes a mixture of pollutants principally ground-level ozone, produced by chemical reactions in the air involving smog forming chemicals.

Front 2

Lethal air pollution episodes in history

Back 2

London England 1952 The weather in Greater London had been unusually cold for several weeks leading up to the event. Because of the cold weather, households were burning more coal than usual to keep warm.

Front 3

composition of pure air by weight

Back 3

1. nitrogen

2. oxygen

3. argon

4. carbon dioxide

5. variety of other gases in lesser amounts

6. water vapor

Front 4

criteria air pollutants

Back 4

criteria air pollutants are ozone, nitrogen oxides, carbon monoxide, sulfur dioxide, particulate matter, and lead.

Front 5

particulate matter (PM)

Back 5

the smaller the number the more dangerous the particle is 2.5 versus 10

Front 6

carboxy hemoglobin is formed when a person inhales what?

Back 6

carbon monoxide

Front 7

what is the major cause of acid rain?

Back 7

is the major contributor is SO2

Front 8

temperature inversion

Back 8

A temperature inversion occurs when the air closer to the ground is cooler than the air above it. When warm air is on top of cold air.

Front 9

the air quality Index

Back 9

air-quality index is used to provide the public with an indication of air-quality in a local area on a daily basis.

Front 10

the standard for carbon monoxide levels during an 8-hour period is:

Back 10

9PPM

Front 11

Federal standards: primary standards set limits to protect?

Back 11

public health, including the health of sensitive populations such as asthmatics, children, and the elderly.

Front 12

Federal standards: secondary standards set limits to protect?

Back 12

public welfare, including protection against decreased visibility, damaged animals, crops, vegetation, and buildings.

Back 13

building related illness

Front 14

illness associated with poor indoor air quality

Back 14

sick building syndrome

building related illness

One can be identified and the other one cannot.

Front 15

sick building syndrome:

Back 15

no specific illness or cause can be identified.

Causes acute health and comfort effects.

Front 16

Building–related illness:

Back 16

describes a diagnosable illness

linked to specific pollutants.

Front 17

Causes of global warming:

listen to recorder may be more.

Back 17

Use of fossil fuels including: petroleum-based fuels.

Chlorofluorocarbon gases used in air conditioners have been linked to the depletion of the ozone layer.

Extreme weather conditions

Deforrestation

Front 18

technological controls

Back 18

several mechanical devices are used to reduce industrial emissions of particulate matter e.g. scrubbers, filters, and electrostatic precipitators.

Front 19

Which of the following is inappropriate for composting?

Back 19

Fats, oils, grease
