World Health Organization pesticide classification

WHO (2005) The World Health Organization recommended classification of pesticides by hazard. 

The World Health Organization (WHO) classification (shown in Table 5) also makes a distinction between toxicity and hazard and recognizes that liquid formulations are more hazardous. This international classification is based on a comparative analysis of the standards adopted by different countries for classifying pesticide toxicity. One new aspect in the WHO classification is the evaluation of pesticide products by concentration of active ingredient and formulation (solid or liquid). Other special considerations are products that cause irreversible effects, those for which the hazard of inhalation exceeds that of oral or skin entry, and those for which human health risks are greater than the risk to animals.

APPENDIX 8 HAZARD CLASSIFICATION OF PESTICIDES BY WORLD HEALTH ORGANIZATION... 

The World Health Organization (WHO) recommended classification of pesticides by hazard, first issued in 1978, has gained wide acceptance. The classification is based primarily on the acute oral and dermal toxicity to rats since these determinations are standard procedures in toxicology.
