Abstract: | Environmental health monitoring and surveillance include activities such as collection of information on the production and use of chemicals; preparation of inventories of waste discharges; measurement of physical, chemical and biological agents in air, water and food, at work place and at home; epidemiological investigations, and collection and analysis of environmental, and health statistical data. There are two main objectives of these activities: estimation of human exposure to potentially harmful environmental factors and timely detection of adverse health effects; and the assessment of environmental conditions in relation to established guidelines and standards. Environmental health monitoring and surveillance projects initiated, organized and implemented by the Specialized Agencies and other bodies of the United Nations system include monitoring of air and water quality and of food and animal feed contamination; pilot projects on air pollution exposure assessment and biological monitoring; and ionizing radiation surveillance. Principles of environmental and health monitoring in occupational environment, and of monitoring and surveillance of environmental health effects are outlined. Two examples are provided of national environmental health surveillance systems.Revised and up-dated text of a paper presented at the World congress on Environmental Health in Development Planning, Mexico City, November 1979.Formerly Manager, Environmental Health Criteria and Standards, and Chief Central Unit, International Programme on Chemical Safety, Division of Environmental Health, World Health Organization, Geneva, Switzerland. |
