RT Report T1 Principles for Evaluating Health Risks to Progeny Associated with Exposure to Chemicals during Pregnancy: Environmental Health Criteria 30 A1 United Nations Environment Programme, A1 World Health Organization, A1 International Labour Organisation, K1 pregnancy K1 chemical K1 DNA K1 chromosome K1 toxic substance K1 genetic K1 nutrition K1 childbirth K1 neonatal disease K1 epidemiology K1 carcinogen K1 embryology SN 92 4 154090 7 YR 1984 FD 1984 LK https://wedocs.unep.org/handle/20.500.11822/29535 UL https://wedocs.unep.org/handle/20.500.11822/29535 NO This document is intended to aid in the design and assessment of studies concerned with exploring the association between exposure to chemicals during pregnancy and defective development. This document includes a description of the use of laboratory data in defining the potential embryotoxic hazards of chemicals and methods of assessing the human risks associated with occupational or environmental exposure to such chemicals. Three major areas are covered including: prenatal toxic manifestations, postnatal manifestations, and short-term tests. This document primarily deals with chemical exposures during pregnancy and should be useful to all those concerned with the evaluation of chemical safety.
