  1. Atmospherical pollution Comenius project

  2. What is the "atmosferical pollution"? • It is the contamination of air because of gases, liquid or solid substances immission that changes the natural atmosferical composition in a great or small area. Comenius project

  3. Natural atmospherical pollution • It is up to the diffusion of ashes or gases produced by volcans and fires; • Most dangerous gases are: clorhydric acid, sulphurouse anhydride and carbon bioxid. Comenius project

  4. Atmospherical pollution made by human activities Best reasons: • Iron and steel factories; • waste/rubbish burners; • Oil refinery; • Cement factories; • Chemical factories; • Heating plants and smoke made by escape-pipe. Comenius project

  5. Classes of polluting elements • Polluting elements produced by human activities; • Natural polluting elements. Classes of atmospherical polluting elements: • Primary elements-> let in as they are; • Secondary elements -> produced by chemical reaction directly into the atmosphere. Comenius project

  6. OUTDOOR POLLUTION: produced by substances into open spaces, • INDOOR POLLUTION: produced by substances that are inside of buildings. • Indoor Air Quality index indicated the quality of air inside of buildings. (We know something as 3,000 pollution particles in the air) Comenius project

  7. Metereology • The polluting substances that are in the air have a concentration that is up to metereological and climatical condition, to temperature and to the wind speed. Comenius project

  8. Effects on healt • Breathing and circolatory problems, • Increasing of cancer, • Empoisoning and change of metabolism; • (in plants) poisoning and death; • Degeneration processes of walls, stones, paints and plasters of buildings. Comenius project

  9. The invisibile pollution particles associated to air water vapour and dusts, produce a dense and dark fog, said SMOG (smoke + fog). Comenius project

  10. Some illness • Pollution provokes: • Breathing difficulties; • Cronic bronchitis; • Cancer. Comenius project

  11. Preventions • Using filters, softeners or other safety devices. • Building factories in windy areas. • Increasing parks and gardens in towns. • Providing incentives for use ecological energies. Comenius project

  12. The air pollution don’t respect any frontier between the countries. It only could be fighted with international planes!!! Comenius project
