New and Revised Test Guidelines Published

The OECD Guidelines for the Testing of Chemicals are a collection of the most relevant internationally agreed test methods used by government, industry and independent laboratories to determine the safety of chemicals and chemical preparations, including pesticides and industrial chemicals. They cover tests for the physical-chemical properties of chemicals, human health effects, environmental effects, and degradation and accumulation in the environment. The OECD has published the 15th Addendum to the Guidelines, consisting of eleven new and three revised Test Guidelines (listed below). The OECD Guidelines for the Testing of Chemicals are available online to subscribers via SourceOECD or they can be purchased from the OECD online bookshop.
