Monitoring cumulative exposure to hazardous pollutants
Besides exposure to single chemical pollutants, people are exposed to the cumulative effects of combined pollutants through air, food, and drinking water.
The objectives of the United States Environmental Protection Agency's (EPA) Cumulative Exposure Project (CEP) are to: (a) estimate exposure levels for a wide variety of toxic pollutants; (b) characterize the national distribution of these estimated exposure levels across communities and demographic groups; (c) identify the types of communities and demographic groups which appear to have the highest exposure levels; and (e) identify potentially important emission sources and pollutants for which information is most uncertain.
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.
