All Flashcards
Catalytic converters significance?
Convert harmful gases (CO, NOx, hydrocarbons) into less harmful ones (CO2, O2, N2, H2O).
Electrostatic precipitators significance?
Use high voltage to ionize particles, then attract them to charged plates for removal.
Alternative energy significance?
Reduces greenhouse emissions and eliminates combustion particulates.
Clean Air Act (USA)?
Regulates air emissions from stationary and mobile sources; sets NAAQS.
Montreal Protocol?
International treaty to protect the ozone layer by phasing out ozone-depleting substances.
EU's Thematic Strategy?
Comprehensive plan to reduce air pollution in the EU across sectors.
Beijing Action Plan?
Plan to address Beijing's air pollution, including limiting cars and promoting clean energy.
Kyoto Protocol?
International agreement to reduce greenhouse gas emissions, focusing on anthropogenic CO2.
Hydrofluorocarbons (HFCs)?
Powerful greenhouse gases, often used as refrigerants.
Perfluorocarbons (PFCs)?
Potent greenhouse gases, used in industrial processes.
Sulfur hexafluoride (SF6)?
Extremely potent greenhouse gas, used in electrical equipment.
Paris Agreement?
Global agreement to limit global warming to below 2°C through mitigation and adaptation.
Vapor Recovery Nozzle?
Device on gas pumps to reduce VOC emissions.
Catalytic Converter?
Device in vehicles to convert toxic gases into less harmful ones.
Wet Scrubber?
Air pollution control device that uses liquid to remove pollutants.
Dry Scrubber?
Air pollution control device that uses dry reagents to remove pollutants.
Electrostatic Precipitator?
Air pollution control device using electrical charge to remove particulates.
