3
Hazardous and Solid Waste
4
Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA)
5
Hazardous Waste Super fund
6
Oil Pollution Act (OPA)
7
Oil Spills
8
Pollution Prevention Act (PPA)
9
Seeks to prevent pollution through the reduced
generation of pollutants at their origin
10
Ionizing radiation
11
enough energy to knock electrons from atoms
forming ions, capable of causing cancer (ex
gamma-Xrays-UV)
12
High Quality Energy
13
organized concentrated, can perform useful work
(ex fossil fuel nuclear)
14
Low Quality Energy
15
disorganized, dispersed (heat in ocean or air
wind, solar)
16
First Law of Thermodynamics
17
energy is neither created nor destroyed, but may
be converted from one form to another
18
Second Law of Thermodynamics
19
when energy is changed from one form to another,
some useful energy is always degraded into lower
quality energy (usually heat)
20
Natural radioactive decay
21
unstable radioisotopes decay releasing gamma
rays, alpha beta particles
22
Half life
23
the time it takes for ½ of something to decay
the mass of a radioisotope to decay
24
Estimate of how long a radioactive isotope must
be stored until it decays to a safe level
25
approximately 10 half-lives
26
Nuclear Fission
27
nuclei of isotopes split apart when struck by
neutrons
28
Nuclear Fusion
29
2 isotopes of light elements (H) forced together
at high temperatures till they fuse to form a
heavier nucleus. Expensive, break even point not
reached yet...too hot.
30
Ore
31
a rock that contains a large enough concentration
of a mineral making it profitable to mine
32
Mineral Reserve
33
identified deposits currently profitable to
extract
34
Best solution to Energy shortage, two things
35
conservation and increase efficiency
36
Surface mining
37
cheaper can remove more mineral, less hazardous
to workers
38
Humus
39
organic, dark material remaining after
decomposition by microorganisms
40
Leaching
41
removal of dissolved materials from soil by water
moving downwards
42
Illuviation
43
deposit of leached material in lower soil layers
(B)
44
Loam
45
perfect agricultural soil with equal portions of
sand, silt, clay
46
Solutions to soil problems
47
conservation tillage, crop rotation, contour
plowing, organic fertilizers
48
Parts of the hydrologic cycle (6)
49
evaporation, transpiration, runoff, condensation,
precipitation, infiltration
50
Aquifer
51
any water bearing layer in the ground
