The OECD Secretariat received almost simultaneously three proposals for an OECD Test Guideline on Direct Phototransformation in Water, i.e. aqueous photolysis. The purpose of this Guidance Document is to situate these proposals in a broad context consisting of the basic concepts of...

This Test Guidance is designed to determine the rate and extent to which metals and sparingly soluble metal compounds can produce soluble available ionic and other metal-bearing species in aqueous media under a set of standard laboratory conditions representative of those generally occurring in...

At this workshop, participants (i) shared information about different types of chemical monitoring programmes conducted by countries and international bodies; (ii) shared experiences of using measured data in environmental exposure assessment; (iii) identified ways to improve monitoring...

This Guidance Document provides information for both the regulated community and regulators to assist with the choice of the most appropriate Guideline to enable particular data requirements to be met while reducing the number of animals used and animal suffering.

This detailed background review paper provides a summary of the relevant literature (up to September 2001) relevant to the standardisation and validation of the rodent uterotrophic bioassay. The rodent uterotrophic bioassay is being validated as part of the OECD Test Guidelines Programme. The...

This document sets out the objectives, organisational context, and plan for a Harmonised Integrated Classification System for Human Health and Environmental Hazards of Chemical Substances and Mixtures.

This document serves as the basis for the first step in the consideration and development of OECD Test Guidelines for the testing of chemicals for endocrine-disrupting effects. OECD Test Guidelines play a critical role in ensuring that efficient and effective procedures are available to identify...
