In this document a strategy is presented to facilitate the ecological risk assessment of organometallic compounds (OM) and organic metal salts (OMS), outlining key steps that are based on elucidation of the fate of these substances in the environment. This document puts forth the recommendation ...

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 paper reviews some general strategies used by OECD Member countries when assessing exposure in the context of risk assessments for existing industrial chemicals.

This Environment Monograph contains the report of the OECD Workshop on Environmental Hazard/Risk Assessment, which took place in London in May 1994.

This Guidance Document concerns using multimedia models, i.e. generic evaluative models that can calculate overall environmental persistence (Pov) and potential for long-range transport (LTRP) covering multiple compartments such as air, water, sediment and soil.

This document is intended to provide universal Guiding Principles that should be considered when developing or augmenting systematic approaches to Weight of Evidence (WoE) for chemical evaluation and Key Elements to formulating a systematic approach to WoE. The ultimate goal is to facilitate that regulators follow a consistent, clear and transparent delivery of evidence using the Principles and Elements described in this document. This can be especially helpful for countries with no existing WoE frameworks or those looking to augment their approaches. It also allows for stakeholders to understand a WoE decision-making process, including potential for unreasonable bias. These Guiding Principles and Key Elements can be employed to develop frameworks that range from simple and pragmatic approaches to more elaborate systems, depending on the context.

The report outlines the technical aspects of the various approaches and methodologies available with respect to the assessment of risks from combined exposures to multiple chemicals. The document draws from approaches applied and experience gained in the regulatory context and will therefore be most relevant to the regulatory authorities addressing chemicals, the regulated community and other interested stakeholders.
