Title The WHO recommended classification of pesticides by hazard and Guidelines to classification 1998-1999
Bibliographic information World Health Organization (WHO), Distribution and Sales Service, 1211 Genève 27, Switzerland, 1998. 61p. Index.
Abstract Part 1 of this document describes the basis of the WHO system for the classification of pesticides according to their acute risk to health. The classification is based primarily on the acute oral and dermal toxicity to the rat (LD50 values). A table shows LD50 values for each class of pesticide: extremely hazardous, highly hazardous, moderately hazardous, and slightly hazardous. The application of the criteria for classification is explained along with the effects of classification on labelling. Part 2 provides lists of products in the 4 hazard classes and a list of pesticides considered unlikely to present acute hazard in normal use. Further tables are provided for determining the hazard class of a formulation. Update of CIS 97-945.
