Introduction

air pollution

-greenhouse effect

-ozone holewater pollutiondamage of forests references

Air pollution

the biggest problem in large cities and in areas with concentrated industrial production

emission of sulphur dioxide nitrogen oxide carbon dioxide

→ climate changes

Page 4: ENVIRONMENT ENVIRONMENT How to protect and destroy it Hegerová Lucie, Lacinová Eva.

Greenhouse effectgreenhouse gases:water,water vapour,

carbon dioxide, methane, nitrogen oxide, and chlorofluorocarbons

fossil fuels, domestic animals, agriculture, disforesting

Ozone layer

30 - 65 km max. amount of O3 - 50 km

O2 → O + O

O2 + O → O3 + 24 kcal

in stratosphere absorbed UV irradiationfall to the earth about 1% of UV

irradiation

Ozone holedecrease of amount of ozone in the atmospheresubstances destroying ozone layer:

freons, halogenidesthe most over Antarctica, North Polevisual disorder and skin cancer, lower

yield of crop, threating of animal and fytoplankton, corrosion of surfaces

Problem solving

using alternative sources of energy(solar, water, wind, geothermal, tidal energies)

encourage of railway and public transportusing unleaded petrol and autocatalyst instalation of flue gas desulphurisation

plants at some power stationencourage tree planting

tidal-přílivflue gas desulphurisation - odsiřování

Water pollutionresult from: harmful industrial processes and

householdssubstandard sewage treatment plantsagriculture:pesticides,fertilizers →nitrates can pollute inland waters waste disposial sitesships

fertilizers-hnojiva waste disposial sites-skládky

sewage treatment plants-čistička odpadních vod

Problem solving

control water from industrial processesmore sewage treatment plantschange farming practices (using

environmentally friendly pesticides)
