The report concludes on the main reasons for such differences, and recommends some measures to overcome some of them.

An addendum to the OECD Guiding Principles on Chemical Accident Prevention, Preparedness and Response to address Natural Hazards Triggering Technological Accidents (Natech) Risk Management has just been published. The addendum consists of a number of amendments to the Guiding Principles and the addition of a new Chapter to provide more detailed guidance on Natech prevention, preparedness and response.

The OECD has published guidance to facilitate the ecological risk assessment of organometallic and organic metal salt substances. A strategy is presented based on key steps that first consider the fate of these substances in the environment, the identification of moieties of concern, and subsequently the selection of an appropriate path forward to either assess the inorganic moiety and/or the individual substance.

In 2011, Brazil joined OECD’s Mutual Acceptance of Data (MAD) system ensuring that its chemical safety test data will be accepted by all 40 countries adhering to MAD. Originally limited to data developed in Brazil on pesticides, biocides and industrial chemicals, it now also includes veterinary products, feed additives, cosmetics, pharmaceutical products, sanitizers, wood preservative and treatments of effluents and natural ecosystems.
