Unit 7 and Unit 8 Flashcards
What are primary pollutants
emmitted from identifiable source
what are point source pollutants
one single identifiable source
what are non point pollutants
a non identifiable source
what are secondary pollutants
produced in atmosphere from reactions in primary
What produced sulfur dioxide
burning fossil fuels and smelting ore
What creates smog
Nitrogen oxide, sun, and O3(ozone)
What pollutants are apart of the Clean Air Act of 1970
CO2, Sulfur dioxide, nitrogen oxide, carbon monoxide, particulate matter, ozone, and lead
What happens in early morning smog
No and hydrocarbons and carbon dioxide are created from traffic
What happens late morning for smog
No is oxidized with oxygen to no2
What happens in the afternoon with smog
Sunlight is here and box and box create the ozone and pans
What is the worst time for smog
3pm
Hat are ways to reduce smog
Reduce driving, drive less, maintain vehicle checks, refuel during less sunlight, avoid gas powered stuff
What are the temperature patterns for temperature inversions
Cold near floor hot above
What creates acid rain
Sulfur and nitrogen(pollutants) react with oxygen and water and create nitric acid and sulfuric dioxide
What forms can acid rain create
Can be rain, snow, fog, hail, dust and gas
What are the effects of acidic rain
Fish can die, eggs won’t hatch, inhibit aluminum in soil, affects breathing
What neutralizes acid rain
Limestone and calcium carbonate
What are the two indoor air pollutants
Asbestos and radon
What is the 2 cause of lung cancer
Radon
What are the 4 pollution reduction techs
Vapor recovery, catalytic converter, wet and dry scrubber
What is MSW
Solid waste
What are waste disposal methods
Sewage, landfill, burning, and illegal dumping
Explain the pros and cons of landfill
Bottom liner suppers contamination but accidents happen, methane can be pumped out for energy
What are the three r of waste
Reduce recycle and reuse
What is thermal pullution
heat in the water creates negative effects for organisms
how does thermal pollution affect coral reefs and wetlands
wetlands: degrades water quality and dificult to clean
Coral reefs: high temperatre means coral bleaching, sediment runoff, and physical breakage of coral
explain oil pollution and effects
oil floats, coating bird wings and marine mammals
explain eutrophication and effects
high excess nutrients means algal blooms, microbes digest the algae taking the 02 allowing fish to die
explain o2 sag curve
o2 sag curve - plot of o2 level vs distance from pollution/demand
explain sediment pollution and effects
high turbidity limits photosynthesis, causing gravel beds to line with sediment preventing fish spawning
explain heavy metal pollution and effects
mercury enters aqautic and bacteria create high toxicity mercury. Mercury poisons nervous system and is the most harmful to the environment and humans
what are endocrine disruptors
chemical that interferes with normal endocrine system and other biological processes
what are effects of endocrine disruptors
birth defects, developmental disorders, and increased risk of cancer
