29
introduction of contaminants into the natural environment that cause adverse change.
Pollution
30
garbage, refuse, sludge, and other discarded solid materials
Solid waste
31
comprises the waste generated by households, businesses, and institutions (e.g., schools) located within municipalities.
municipal solid waste (MSW)
32
solid waste with properties that make it dangerous or potentially harm- ful to human health or the environment
Hazardous waste
33
include infectious and pathological wastes from hospitals, including sharps such as lancets and needles in syringes
Hazardous wastes
34
contamination of the air by substances
Air pollution
35
represents the single most dangerous air pollutant
Ozone (O3)
36
When nitrogen is released during fuel combustion it combines with oxygen atoms to create nitric oxide (NO).
Nitrogen Oxides (NOx).
37
gas is found in fumes produced in burning fuel
Carbon monoxide
38
mixture of solids or liquid droplets in the air that are categorized by size
Particulate matter (PM10 and PM2.5)
39
is a naturally occurring mineral fiber that was previously used for insulation and fireproofing material.
Asbestos
40
another indoor air pollutant, which can be associated with allergic reactions and respiratory difficulties, such as asthma.
Mold
41
also known as secondhand smoke
Environmental tobacco smoke (ETS)
42
the smoke inhaled and exhaled by the smoker
main- stream smoke
43
the smoke that comes off the end of a burning tobacco product
sidestream tobacco smoke
44
The involuntary inhalation of ETS by nonsmokers is referred to as
passive smoking
45
dense, colorless, odorless noble gas that occurs naturally in the soil as the product of the radioactive decay of radium
Radon
46
any physical or chemical change in water that can harm living organisms or make it unfit for other uses, such as drinking, domestic use, recreation, fishing, industry, agriculture, or transportation.
Water pollution
47
single identifiable source that discharges pollutants into the water, such as a pipe, ditch, or culvert.
Point source pollution
48
Includes all pollution that occurs through the runoff, seepage, or falling of pollutants into the water.
Nonpoint source pollution
49
WATER POLLUTANTS
Biological Pollutants Non-biological Pollutants
50
process in which energy is emitted as particles or waves
Radiation
51
noise emitted from all sources except noise at the industrial workplace.
Community noise
52
means low danger from the sun's UV rays for the average person.
0 to 2
53
moderate risk of harm from unprotected sun exposure. Stay in shade near midday when the sun is strongest.
3 to 5
54
means high risk of harm from unprotected sun exposure. Protection against skin and eye damage is needed.
6 to 7
55
very high risk of harm from unprotected sun exposure. Take extra precautions because unprotected skin and eyes will be damaged and can burn quickly.
8 to 10
56
means extreme risk of harm from unprotected sun exposure. Take all precautions because unprotected skin and eyes can burn in minutes.
