Industrial and domestic heating emissions as air pollutants
The combustion of fuel for domestic heating and energy production represents the most common and most widespread source of atmospheric pollution. This produces hot air, carbon dioxide, carbon monoxide, and incompletely burned carbon, water vapour, and oxides of nitrogen, sulphur and other trace gases. Emissions of gases of combustion by industry are much more restricted both in area and numbers of sources. However, combustion for industrial or commercial purposes can be the major source of pollutants in some places, as in the instance of old coal-fired power plant.
The region of Silesia in Poland is highly dependent on coal as a source of energy and domestic heating. The local coal is of poor-quality and produces excessive amounts of airborne particulates and sulphur dioxide which in winter are up to 10 times the EEC/EU limits. Organic compounds in the smog called polycyclic aromatic hydrocarbons (PAH) are causing genetic defects in foetuses and cancer -- the frequency distribution maps of particulate emissions and cancer closely correspond, and the infant mortality rate in the worst polluted areas is 30 per thousand, twice the national average and five times the OECD average.
The Encyclopedia of World Problems and Human Potential is a collaboration between UIA and Mankind 2000, started in 1972. It is the result of an ambitious effort to collect and present information on the problems with which humanity is confronted, as well as the challenges such problems pose to concept formation, values and development strategies. Problems included are those identified in international periodicals but especially in the documents of some 60,000 international non-profit organizations, profiled in the Yearbook of International Organizations.
The Encyclopedia includes problems which such groups choose to perceive and act upon, whether or not their existence is denied by others claiming greater expertise. Indeed such claims and counter-claims figure in many of the problem descriptions in order to reflect the often paralyzing dynamics of international debate. In the light of the interdependence demonstrated among world problems in every sector, emphasis is placed on the need for approaches which are sufficiently complex to encompass the factions, conflicts and rival worldviews that undermine collective initiative towards a promising future.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
