APES Unit 7 Note Cards - Laura Vu, Period 4

Note cards on air pollution

Vehicle Exhaust

Vehicle Exhaust → Catalytic converter → Vehicles use catalytic converters to transform harmful exhaust gases into less toxic substances

Power Plants

Power plants → Scrubbers → Power plants use scrubbers to neutralize/capture pollutants with powdered sorbents (dry) or limestone slurry (wet)

Factories

Factories → Electrostatic precipitators → Factories use electrostatic precipitators to remove particles using electricity to draw them to oppositely charged plates

Construction Dust

Construction dust → Water sprays → Water sprays are used to manage construction dust to wet surfaces, which make the dust settle and adhere to them

Agriculture

Agriculture → Methane digesters → Methane digesters mitigate pollution from agriculture by capturing and converting methane emitted from livestock manure into renewable energy

Landfills

Landfills → Methane capture systems → Landfills use methane capture systems made of wells and pipes to collect methane gas before it can integrate into the atmosphere

Gas Stations

Gas stations → Vapor recovery nozzles → Gas stations use vapor recovery nozzles to draw toxic fumes back into an underground storage tank

Household Products

Household products → Low-VOC products → Low-VOC products reduce pollution from household products by releasing fewer VOCs into the indoor air

Wood Burning

Wood burning → Smoke filters → Smoke filters reduce pollution from wood burning by capturing PM and can remove VOCs using activated carbon

Indoor Air

Indoor air → Air purifiers → Air purifiers reduce indoor air pollution by drawing in and passing air through filters by using a fan, capturing PM and VOCs and circulating back clean air
