Can we trust real time measurements of lung deposited surface area concentrations in dust from powder nanomaterials ? NOETUDE/P2016-051 | 2016A laboratory comparison between various methods for real-time measurements of lung deposited surface area (LDSA) using spherical particles and powder dust with specific surface area ranging from 0,03 to 112 m2/g was conducted. Based on these…

DUSTINANO: a pre-normative research project towards a harmonized approach to evaluate the nanomaterials dustiness NOETUDE/C2014-111 | 2014The propensity of bulk nanomaterials powders to be released as particles, the so called dustiness, is an important consideration for worker exposure and the design and operation of many industrial or research processes. OECD considers that…

Exposure assessment to engineered nanomaterials within the French EpiNano program: inter-method reliability study ET2015-003/C2016-061 | 2016Objective: Inter-method reliability is a measure of the ability of two different methods which evaluate the same underlying exposure to yield similar results on the same subjects. In this study we compared an observational “EpiNano-method…
