Test outline for test number 4 March 7, 2015
AIR POLLUTION
1. percentages of gases
2. HUMAN RESPIRATORYT SYSTEM-nose, pharynx, larynx, trachea,
bronchus, bronchiole, alveoli
3. Criteria pollutants-O3, SO2, VOCs, NOx,Particulates,CO
4. Lung diseases-asthma, cancer, emphysema
GLOBAL WARMING1.CO2 IS MEASURED AT Mauna Loa
2.Know what peaks and valleys mean from the CO2 charts. Peaks in winter,
valleys in summer.
3.Global warming (greenhouse gases) -know gases involved-Carbon Dioxide
(CO2), Methane (CH4) ,
and nitrous oxide (N2O)
4.Effects of global warming- threat magnifier etc. etc.
6. Transpiration –evaporation of water from leaves
7.GWP-global warming potential- using CO2 as 1-nitrous oxide,sulfur
hexafluoride
KNOW EVERYTHING DISCUSSED
OZONE DEPLETION
1.
2.
3.
4.
5.
6.
7.
8.
9.
Know o3 as the formula for ozone-protects us against uv light
Know the meaning of the electromagnetic spectrum
Know wavelengths of visible light, UV A, UVB AND UVC
Know chlorine monoxide (CLO)
Know work of Mario Molina and friends
Know about polar stratospheric clouds and ozone depletion
Know about Dobson units=.01mm
Know effects of UV light on skin
Know elements in CFC’s, HCFCs and HFC
1.TEMPERATURE INVERSIONS
Normal
inversion
Cooler
cold air
Cool
warm air
Warm
cold air
Know what happened in Chicago-CO (carbon monoxide) set off alarms
ACID RAIN-Know what pH means- Normal rain has a pH of 5.6 (slightly acidic)
Sacle range 0-14 where 7 is neutral-above 7 is basic, below 7 is acidic
Most aquatic animals can’t tolerate low pH levels.
PHOTOCHEMICAL SMOG-Ground level ozone, PAN (peroxyacylnitrates).
ENERGY SOURCE IS THE SUN
SCRUBBERS (INVOLVE A CHEMICAL RTEACTION TO PRODUCE A SOLID WHICH IS
LANDFILLED) AND ELECTROSTSATIC PRECIPITATORS CREATES A ZERO CHARGE
TO PRECIPITATE OUT PARTICULATES.
WATER POLLUTION
1 KNOW 8 MAJOR POLLUTANTS
2.KNOW THE ORGANISMS THAT CAUSE DISEASE-TYPHOID AND CHOLERA BACTERIUM,
SCHISTOSOMIASIS IS CAUSEDE BY A WORM, POLIO-VIRUS, DYSENTARYAMOEBA AND BY BACTERIA
3. SEWAGE TREATMENT-PRIMARY, SECONDARY-OXIDATION, ACTIVATED
SLUDGE , TRICKLING FILTERS
4. WHAT HAPPENS TO THE SLUDGE
a-ANAEROBIC DIGESTERS-METHANE GAS
b. LANDFARM IT FOR CROPS(*NON-EDIBLE)
c. LANDFILL IT
d.KNOW BOD-BIOCHEMICAL OXYGEN DEMAND WHICH IS EXPRE4SSED IN
mgO2/l of water.
5. SEWAGE treatment IS BASICALLY A NATURAL PROCESS PERFORMED BY
MICROBES
KNOW EVERYTHING DISCUSSED
