4
Carbon Monoxide (CO) Nitrogen Oxides (NOx) Sulfur Oxides (SOx) Industry Transportation Power generation (burn fossil fuels) Volcanoes Forest Fires Dust storms
5
Negatively affects human heath Respiratory system cardiac system eye irritation Cancer Environment Damages plants, animals, ecosystems
6
Reduce/Minimize Alternative fuels Fuel efficiency Public transportation Clean Energy sources Recycle Regulations
7

8
Lead (Pb) Metal processing (smelting) Batteries Transportation fuels Particulates dustsmoke salt spray fumes fogmist Volcanoes Forest Fires Dust storms
9
Negatively affects human heath Respiratory system cardiac system eye irritation Cancer Environment Damages plants, animals, ecosystems
10
Lead Alternative fuels Fuel efficiency Public transportation Scrubbers in metal industry Regulations Particulate Minimize construction and exposed ground Reduce overall pollution Less driving Alternative fuels

12
SO 2 & NO 2 + H 2 O = acid rain * Industry * Transportation * Power generation (burn fossil fuels) * Volcanoes * Forest Fires * JUST ADD WATER
13
Damages leaves, trees eventually die Accumulates in soils damaging plants Accumulates in lakes/streams kills fish disrupts entire ecosystem Damages certain building materials (limestone, marble, concrete) Reacts with certain metals Problem near industrial areas Areas with non-reactive bedrock/soil
14
Clean energy (not fossil fuels especially coal) Scrubbers on industry smoke stacks Can increase lake pH but expensive and temporary

16
NOx + hydrocarbons (transportation exhaust) + solar radiation = TROPOSPHERIC OZONE + other hazardous substances Big cities warm sunny climate Worse if air stays trapped in local area
17
Lung irritant Interferes with photosynthesis Damages plastic, rubber, and elastic materials
18
Use mass transportation Fuel efficient vehicles Don’t fill gas tanks during daylight hours
20
https://www.youtube.com/watch?v=lBu3vltczRw IN THE STRATOSPHERE
21
Ozone (O 3 ) molecules in STRATOSPHERE destroyed by CFC chemicals - from Propellents Air conditioning Refridgerators solvents
22
Skin cancers Cataract (eye damage) Decreased plant health Damage to ocean phytoplankton
23
Problem noticed in 1970s Montreal Protocol 1987 170 nations agreed to reduce or eliminate the production/use of CFC chemicals. Showing improvement – expected to be ‘normal’ by 2050
24

25
Greenhouse effect – gasses in our atmosphere keep temperature moderated by trapping sun’s energy It is good and important for life Carbon dioxide CO 2 Methane CH 4 Water vapor H 2 O See Atmosphere Structure notes for sources Before we talk about Global warming….

27
an increase in greenhouse effect (temperatures) Because of human caused increase in CO 2 emissions Burn fossil fuels deforestation
28
Ice melt (glaciers, Arctic, Antarticta) Sea level rise Ocean Acidification Extinction, spread of tropical diseases, etc.
29
Clean energy, energy efficiency, car pool Less use of fossil fuels Reforestation https://www.youtube.com/watch?v=oJAbATJC ugs

31
Coal, Natural Gas, Oil Formed from ancient plants/animals (350-225 Million years ago) Underground mined or drilled/pumped out Produce air pollutants and greenhouse gasses when burned https://www.youtube.com/watch?v=F6VCTh1iWdM
32
Solar Wind Hydroelectric (dams – tides) Geothermal Expensive to set up, manufacturing can produce pollutants, localized area
