This guidance document is part of the OECD effort to provide guidance for assessing the hazards of chemical substances while gaining efficiencies and improving animal welfare. The approach described in this guidance document is to consider closely related chemicals as a group, or category,...

Several models, tools and methods have been published in the past 20 years to include bioavailability in risk assessment and several OECD member countries already have developed frameworks and published guidance documents for taking metal specificities into account in environmental risk...

This guidance document is part of the OECD effort to provide guidance for assessing the hazards of chemical substances while gaining efficiencies and improving animal welfare. The approach described in this guidance document is to consider closely related chemicals as a group, or category,...

This document is a tool to support regulatory authorities’ decisions on the hazard of specific chemicals when they receive test results from a Test Guideline (TG) or draft TG for the screening/testing of chemicals for endocrine disrupting properties. The contexts for these decisions will vary,...

This document provides guidance on how to use the OECD (Q)SAR Application Toolbox to build chemical categories according to the OECD Guidance on Grouping of Chemicals. It is part of an overall effort to provide guidance on the use of the (Q)SAR Application Toolbox.

This guidance document was originally published in 2012 and updated in 2018 to reflect new and updated OECD test guidelines, as well as reflect on scientific advances in the use of test methods and assessment of the endocrine activity of chemicals. The document is intended to provide guidance...

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...

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 review paper is based on the compilation of more than 600 pelagic and benthic testing methods. It has been created to assist the OECD National Co-ordinators in their discussions regarding the identification of aquatic toxicity text methods to be included in the OECD Test Guidelines programme.

This paper reviews some general strategies used by OECD Member countries when assessing exposure in the context of risk assessments for existing industrial chemicals. It is intended as an initial overview, not as a comprehensive review. Strategies for source assessment, one of the elements of...
