Guidelines for drinking-water quality. 2nd ed. Volume 2. Health criteria and other supporting information.
Geneva, Switzerland, WHO, 1996. xvi, 973 p.The first edition (1984-85) of guidelines for drinking water quality was intended for use as a basis for the development of national standards to ensure the elimination--or significant reduction--of constituents of water known to be hazardous to health. This revised edition includes many drinking water contaminants not included in the earlier book and revises some of the recommended guideline values in light of new scientific information. This volume explains how guideline values for drinking water contaminants are to be used; defines the criteria used to select the chemical, physical, microbiological, and radiological contaminants included; and evaluates the effects of these substances on human health. The guidelines presented were developed by over 200 experts from 40 countries. It is emphasized that guideline values should be considered in the context of environmental, social, economic, and cultural conditions rather than as absolutes. Moreover, guideline values are recommended only when control techniques are available to remove or reduce contaminant concentrations to desired levels. Source protection is almost invariably the best method of ensuring safe drinking water.
New York, New York, Oxford University Press, 1992. xiv, 385 p.The World Resources Institute, the UN Environment Programme, and the UN Development Programme collaborate to produce the World Resources series to provide organizations and individuals with accessible and accurate information on the trends and conditions of natural resources and protection of the environment. This information is needed to reach sustainable development, eliminate poverty, improve the standard of living, and preserve biological life-sustaining systems. This 5th volume stresses sustainable development as does the 1992 UN Conference on Environment and Development. Part I, entitled Sustainable Development, includes an overview chapter and 3 case studies of possible means to achieve sustainable development in industrialized countries, low income countries, and rapidly industrializing countries. Part II focuses on one region of the world, Central Europe, to discuss how it was able to degrade the environment, the magnitude of the damage, and what possible steps to take to ameliorate the situation. Part III addresses basic conditions and trends, key issues, major problems and efforts to resolve them, and recent developments in population and human development, food and agriculture, forests and rangelands, wildlife and habitat, energy, freshwater, oceans and coasts, atmosphere and climate, and policies and institutions (governmental and nongovernmental organizations). Part IV lists core and supporting data from the World Resources Data Base. This volume contains an index and a World Resources Data Base index.
Geneva, Switzerland, UNCED, Secretariat, 1992 Apr. , 116 p. (E.92.I.15)The UN Conference on Environmental and Development Preparatory Committee (UNCED) agreed on an action plan of global partnership for sustainable development and environmental protection entitled Agenda 21 to be adopted at the June 1992 UNCED in Rio de Janeiro. The priority actions are a call for action to achieve a prospering, just, and habitable world. These actions also promote a fertile, shared, and clean planet via extensive and responsible public participation at local, national, and global levels. Since most environmental problems originate with the failures and inadequacies of the current development process, the 1st action centers around revitalizing growth with sustainability including international policies to accelerate sustainable development in developing countries and integration of environment and development in decision making. The 2nd action is achieving sustainable living by attacking poverty, changing consumption patterns, and recognizing and acting on the links between population dynamics and sustainability, and providing basic health needs to preserve human health. The 3rd action addresses human settlements including urban water supplies, solid wastes management, and urban pollution and health. The 4th and 7th action plans incorporate the most subtopics. The 4th action plan calls for efficient resource use ranging from land resource planning and management to sustainable agriculture and rural development. The 7th plan is a call for individuals and groups to participate and be responsible for sustainable development. The major identified groups are women, children and youth, indigenous people, nongovernmental organizations, farmers, local authorities, trade unions, business and industry, and the scientific and technological community. The 5th plan addresses global and regional resources including protection of the atmosphere, the oceans and seas, and sustainable use of living marine resources. The 6th plan deals with management of toxic and hazardous chemicals and radioactive wastes.
