OECD improving guidelines on risk assessment and management of nanomaterials

July 31st, 2014

In early July this year the OECD published a report on the physico-chemical properties of nanomaterials, along with test guidelines. This is part of OECD’s Programme on the Safety of Manufactured Nanomaterials.

An ongoing effort is being made to improve the testing and safety of engineered nanomaterials, which includes the coordination of several projects by the Working Party on Manufactured nanomaterials (WPMN). The aim of WPMN is to improve the currently available guidance for nanomaterials, which are based largely on guidance on the bulk form of substances, rather than being nano-specific.

As a part of the programme, a range of nanomaterials which are already on the market are being tested for their different properties, including toxicology and ecotoxicology, environmental fate and physico-chemical properties. It is hoped that a better understanding of the behaviour and properties of nanomaterials will be developed from the studies.

PFA is actively following the progress in regulatory approach to nanomaterials, and is available for consultation for nano-specific risk assessment, including registration updates to REACH dossiers for the nano-form of a bulk material.
