Abstract
The present work is focused on the measurement of workers exposure to nano-TiO2
in the life cycle steps of depollutant mortars. It has been done in the framework of the
SCAFFOLD project, which aims at the management of potential risks arising from the use of
manufactured nanomaterials in construction. Main findings can be summarized as follows: (1)
The occupational exposure to nano- TiO2 is below 0.3 mg/m3 for all measured scenarios. The
highest concentrations were measured during the cleaning task (in the nano- TiO2
manufacturing process) and during the application (spraying) of depollutant coatings on a wall.
(2) It was found a high release of particles above the background in several tasks as expected
due to the nature of the activities performed. The maximum concentration was measured
during drilling and during adding powder materials (mean total particle concentration up to
5.591E+04 particles/cm3 and 5.69E+04 particles/cm3). However, considering data on total
particle concentration released, no striking differences have been observed when tasks have
been performed using conventional materials in the sector (control) and when using materials
doped with nano-objects.
