A survey on the state of nanosafety research in the European Union and the United States.

Researchers in the field of environmental safety and health of nanomaterials (nanosafety) were surveyed between September 2017 and January 2018 to obtain a snapshot on the state of investigations in this field. The data received from 84 respondents give information on exposure pathways, methods, biologic and toxic effects, dose metrics and range, criteria for selecting benchmark materials, and on problems that are considered urgent in the field. The results can help guide research strategies and funding schemes related to nanosafety of nanoparticles. It is intended to repeat this survey every few years, to follow developments of the field.
