Control Banding Approaches for Nanomaterials

TNO Research Group Quality and Safety PO Box 360, 3700 AJ Zeist Netherlands ?* Author to whom correspondence should be addressed. E-mail: dick.brouwer{at}tno.nlReceived April 28, 2012. Accepted April 18, 2012. Control banding (CB) has been developed as a pragmatic tool to manage the risk resulting from exposure to a wide variety of potentially hazardous substances in the absence of firm toxicological and exposure information. Currently, the CB approach is applied for emerging risks such as nanoparticles, by the development of various CB-based tools. Six of these are compared. Despite their similarity, i.e. combining hazard and exposure into control or risk bands, the structure, the applicability domains, and the assignment of the hazard and exposure bands, show differences that may affect the consistency of the resulting outcome amongst the various CB tools. The value of the currently available CB tools for nanomaterials can be enhanced by transparently elucidating these differences for user consideration during the selection of a tool for a specific scenario of application.

Risks and Control of Nanomaterials

TREVOR OGDEN*
British Occupational Hygiene Society, Melbourne Business Court, Derby DE24 8LZ, UK ? *Author to whom correspondence should be addressed. +44 1332 298101 ogden{at}ogs.org.uk Received April 28, 2012. Revision received April 20, 2012. Accepted April 20, 2012. In this issue we bring together 12 articles on
nanomaterials and approaches to risk control. The issue opens with a review by Eileen Kuempel and colleagues of the research needs for effective management of these materials. This is followed by
two items on tools for control: a review of control banding and a report of discussions on reference values. Then an article describes the development of a practical generic approach to control, applying the popular tool Stoffenmanager to nanoparticles.
After this come two articles on exposure: one in the new field of manufacture of nanotubes …
