Propylene Oxide - Environmental Health Criteria 56
United Nations Environment Programme, World Health Organization, International Labour Organisation

Although only key references essential for the evaluation of the risks for human health and the environment are cited, this document is based on a comprehensive search of the available original scientific literature, while valuable information has also been obtained from various reviews. The document focuses on describing and evaluating the risks of propylene oxide for human health and the environment.

Magnetic Fields - Environmental Health Criteria 69
United Nations Environment Programme, World Health Organization, International Labour Organisation

This document comprises a review of data of effects of magnetic field exposure on biological systems, pertinent to the evaluation of health risks for man. The purpose of the document is to provide an overview of the known biological effects of magnetic fields, to identify gaps in this knowledge so that direction for further research can be given, and to provide information for health authorities and regulatory agencies on the possible effects of magnetic-field exposure on human health, so that guidance can be given on the assessment of risks from occupational and general population exposure.

Diaminotoluenes - Environmental Health Criteria 74
United Nations Environment Programme, World Health Organization, International Labour Organisation

Diaminotoluenes are synthetic aromatic aimines (total of 6 isomers). The isolated, purified isomers are colourless crystals, while the commercial isomeric mixtures are light yellow to tan (Meta-diaminotoluene), or light grey to purple (Ortho-diaminotoluene) solids. Diaminotoluenes are soluble in hot water, alcohol, ether, and hot benzene. When heated, they emit toxic fumes of nitrogen oxides.

Lead: Environmental Aspects - Environmental Health Criteria 85
United Nations Environment Programme, World Health Organization, International Labour Organisation

Lead is a bluish or silvery-grey soft metal. With the exception of the nitrate, the chlorate, and, to a much lesser degree, the chloride, the salts of lead are poorly soluble in water.This document, although based on a thorough survey of the literature, is not intended to be exhaustive in the material included. In order to keep the document concise, only those data which were considered to be essential in the evaluation of the risk posed by lead to the environment have been included

Aldrin and Dieldrin - Environmental Health Criteria 91
United Nations Environment Programme, World Health Organization, International Labour Organisation

Aldrin and dieldrin are the common names of insecticides containing 95% HHDN and 85% HEOD, respectively. Throughout this monograph the names aldrin and dieldrin are used, although concentrations determined in the different matrices are actually those of the active molecules HHDN and HEOD. Aldrin is readily metabolized to dieldrin (HEOD) in plants and animals. Only rarely are aldrin residues present in food or in the great majority of animals, and then only in very small amounts. Therefore, national and international regulatory bodies have considered these two closely related insecticides together. The practicality of considering them jointly is further emphasized by the lack of significant difference in their acute and chronic toxicity and by their common mode of action.

Directory of Experts and Institutions on Soils and Fertilizers in Africa
United Nations Environment Programme

The African Ministerial Conference on the Environment (AMCEN) decided and recommended the establishment of Eight Regional Technical Cooperation Networks on environment and ecodevelopment in Africa during their meeting in Cairo, Egypt, in December 1985. Paramount among the decisions and recommendation made in establishing the Networks were: Cooperation among the technical and research institutions of African States should be strengthened and developed through the exchange of information and the conduct of the basic studies and scientific research necessary for the environmentally sound utilization of African resources; Strengthening and development of technical co-operation among African Countries through the development of horizontal scientific and technical links between national departments in specific areas.

Pentachlorophenol - Environmental Health Criteria 71
United Nations Environment Programme, International Labour Organisation, World Health Organization

Pure pentachlorophenol (PCP) consists of light tan to white, needlelike crystals and is relatively volatile. It is soluble in most organic solvents, but practically insoluble in water at the slightly acidic pH generated by its dissociation (pKa 4.7). 1-lowever, its salts, such as sodium pentachloro-phenate (Na-PCP), are readily soluble in water.

Guidelines for Environmental Assessment of Development Projects
United Nations Environment Programme, Asian and Pacific Development Centre

The purpose of the Test Model is to make available to the policy and decision makers environmental information in a form they can readily use. It facilitates development decisions that are conducive to making resources available on a sustained basis. This recognizes the symbiotic and mutually supportive relationship between development and environmental enhancement.
