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

This document describes the state of knowledge of the adverse outcome pathway (AOP) for skin sensitisation initiated by covalent binding to proteins, assesses the weight-of-evidence supporting the AOP, identifies the key events, and identifies databases containing test results related to key events.

This paper reviews what is known about the responses of molluscs to endocrine disrupting chemicals (EDCs), to consider whether it would be desirable and feasible to standardise mollusc-based partial- and full-lifecycle tests that are sensitive to EDCs and to other chemicals.

This paper provides methods for both the mechanistic evaluation of the action of Endocrine Disrupter Chemicals (EDCs).

This document presents a review of fish toxicity testing for the regulatory purpose of chemical safety. The main focus is on fish toxicity, but fish bioaccumulation is also considered where relevant.

This title reports the state-of-the-art advancements in modeling and characterization of fundamental and the recently designed carbon based nanocomposites (graphenes, fullerenes, polymers, crystals and allotropic forms). Written by leading experts in the field, the book explores the quantification, indexing, and interpretation of physical and chemical exotic properties related with space-time structure-evolution, phase transitions, chemical reactivity, and topology. Exotic Properties of Carbon Nanomatter is aimed at researchers in academia and industry.

The term "emerging contaminants" and its multiple variants has come to refer to unregulated compounds discovered in the environment that are also found to represent a potential threat to human and ecological receptors. Such contaminants create unique and considerable challenges as the push to address them typically outpaces the understanding of their toxicity, their need for regulation, their occurrence, and techniques for treating the environmental media they affect. With these challenges in mind, this handbook serves as a primer regarding the topic of emerging contaminants, with current and practical information to help support the goal of protection where they are encountered. Features Explores the definition, identification, and life cycle of emerging contaminants. Reviews current information on sources, toxicology, regulation, and new tools for characterization and treatment of: 1,4-Dioxane (mature in its emerging contaminant life cycle) Per- and polyfluoroalkyl substances (PFASs; a newer group of emerging contaminant) Hexavalent chromium (former emerging contaminant with evolving science) 1,2,3-Trichloropropane (progressing in its emerging contaminant life cycle) Provides thoughts on opportunities in managing emerging contaminants to help balance uncertainty, compress life cycle, and optimize outcomes.

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.
