The OECD Working Party on Manufactured Nanomaterials (WPMN) has recently published several new reports in its Series on the Safety of Manufactured Nanomaterials, focusing on guiding principles for measurements of physical-chemical parameters, a physical-chemical decision framework and updates of the developments from the delegations. The purpose of these reports is to provide up-to-date information on the OECD activities related to human health and environmental safety.

New OECD WPMN reports 2019:

• No. 91 - Guiding Principles for Measurements and Reporting for Nanomaterials: Physical Chemical Parameters (PDF) 
• No. 90 - Physical-Chemical Decision Framework to inform Decisions for Risk Assessment of Manufactured Nanomaterials (PDF)
• No. 89 - Developments in Delegations on the Safety of Manufactured Nanomaterials - Tour de Table (PDF)

A full list of publications in the Series on the Safety of Manufactured Nanomaterials is available on the OECD WPMN website via http://www.oecd.org/env/ehs/nanosafety/publications-series-safety-manufactured-nanomaterials.htm
