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.

This document provides the second edition of Guidance Document 23 on Aqueous-Phase Aquatic Toxicity Testing of Difficult Test Chemicals.

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 contains guidance for using the summary exposure information reporting formats, which were developed by the OECD Ad Hoc Group on Reporting Summary Exposure Information.

This paper presents internationally harmonised generic and technical terms used in chemical hazard/risk assessment which will help facilitate the mutual use and acceptance of the assessment of chemicals between countries.

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.

This document focuses on the health and environmental hazards of mixtures.

This guidance document has been prepared to support technical aspects of the OECD skin absorption test guidelines. In particular is discusses the various aspects of in vivo vs. in vitro testing.

This guidance provides additional information on the conduct of studies performed using Test Guidelines 451, 452 and Test Guideline 453.

This document provides a description of a Harmonised System for the Classification of Chemicals which are Hazardous for the Aquatic Environment and guidance to how the system will work.
