What is Air pollution?

CAuses

> aerosols or gases suspended in the air

Caused by humans

> aerosols: directly from the sources or through chemical reaction in the air

> smog: ozone created when sunlight reacts with certain chemicals

Natural sources

- volcanic erruptions

- wild fires

- sand/dust storms

- pollrn from plants

- burning fossil fuels

- car emissions

- industrial emissions

- open burning of garbage

- agricultural activities

- indoor air pollution

> inhalation has a drastic impact on human health

- severe respiratory problems

- triggering of heart attack

- skin problems

- cancer forms

- affects on unborn babies

=> can result in premature death

Effects

Environmental effects

- acid rain

- increase of algae

- global warming

- ozone depletion

- impact on wildlife

- global climate change

Primary Pollutants

> directly put in the air

e.g.: car exhaust, volcanic ash industrial smoke

different ways of air pollution

Secondary Pollutants

> form from chemical reactions

e.g.: smog and ozone are produced when sunlight reacts with car exhaust

Top 3 affected countries

China - ca. 11 000

USA - ca. 5000

India - ca. 2000

Germany:

Biggest in Europe ca. 640

Solutions

- public transportation > less emissions by cars

- better household practices

- conserving energy

=> renewable energies

=> less burning of fossil fuels
