A reaction that requires the absorption of light by atoms/molecules
What is a photochemical reaction
Main cause of tropospheric ozone
What is the combustion engine / What are burning fossil fuels
A solution which involves changing human behaviour
What is daily activities to reduce fossil fuel/combustion engine use e.g. public transport/cycling/walking
The main climatic variable in producing smog
Sunlight
A city in Brazil with frequent thermal inversion and trapped smog
Where is Sao Paulo
Toxic at ground level, created in many photochemical reactions
What is Ozone
Formed from the reaction of primary pollutants
What are secondary pollutants
A strategy for reducing photochemical smog through regulation
What are higher taxes for companies for burning fossil fuels (or other regulatory method)
Can reduce photochemical smog quickly
What is rain
The number of people who die prematurely each year due to air pollution (according to UNEP estimates)
1 Million People
Released from burning fossil fuels, this contributes to smog as well as acid rain
What is sulphur
Geographical regions that makes photochemical smog more highly concentrated
Technology in the car engine which reduces nitrogen oxide formation
what is a catalytic convertor
This occurs when warm air overlays cooler air below
What is a thermal inversion
Particles that can enter your blood stream
What are PM 2.5
Created in combustion engines, this gas contributes to acid rain and photochemical smog
What is Nitrogen Oxide(s)
Primary pollutants in the formation of photochemical smog
What are VOCs (Volatile Organic Chemicals) and NOx (Nitrogen oxide/dioxide)
What is a band-aid solution to air pollution issues like photochemical smog
Reforestation and city greening.
The type of air that sinks into valley surrounded by high mountains
What is dense
What is a secondary pollutant?
What are pollutants formed during chemical reactions of pollutants released into the environment.
What is released when fossil fuels are not completely burned
What is particulate matter (PM10 / pm2.5)
Benzene, Methylene chloride and Formaldehyde are all examples of this group of primary pollutants
What are volatile organic chemicals (VOCs)
A technology that can reduce smog
What is a smog-free tower in Rotterdam!
The worst geographic situation for smog
what is a valley city, surrounded by high mountains, with an adjacent large body of water.
In the newly invented smog tower in Rotterdam, these special souvenirs are made from the captured pollutants
What is jewelry
