This webpage aims to give access to practical tools on environmental risk assessment and management of chemicals. It describes the work flow of environmental risk assessment and management with links to relevant OECD products that can be used in each step of the work flow. The Toolkit has been revised 1) to include resources other than OECD products, and 2) to incorporate three examples (i.e. textile dye, pesticide and environmental quality standard setting) which show the risk assessment steps involved in each case.

*Click on any step in the flowchart to jump to a brief explanation of the steps and relevant OECD products.

For a list of definitions, see the document Descriptions of Selected Key Generic Terms used in Chemical Hazard/Risk Assessment.

NOTE: This web site does not provide extensive guidance for all aspects of Risk Assessment, but focuses on products and tools developed in the OECD Environment, Health and Safety Programme.
