The aim of H2020 SAbyNA task 7.1 (T7.1) has been to collect sector-specific typical activities that can be associated to relevantreleases of nanoforms (NFs) to the environment or to direct human exposure for the paint and 3D printingsectors. The current deliverable D7.1 (submitted in March 2021) compiles the results of T7.1. Interviews were held with the industrial Work Package 7 (WP7) partners, ALLIOS and Nouryon for paints andLATI and LEITAT-3D Hub for 3D printing in order to identify sector-specific activities, relevant releases to theenvironment or direct human exposure and to identify commonly used nanomaterials and matrix materials inthese sectors. This has been complimented with a joint questionnaire with WP6 partners for companies and ajoint SAbyNA-SbD4Nano questionnaire (preliminary results are presented for the SAbyNA-SbD4Nanoquestionnaire).A literature review has been performed for the paints and 3D printing sectors to identify sector-specific activitiesand releases of associated nanoforms. For the paints sector, 52 relevant papers were identified and 28 papersfor the 3D printing sector including non-academic literature, i.e. The National Institute for Occupational Safetyand Health (NIOSH) publications. The identified papers were reviewed for information on activities,measurements and other parameters. The literature review is presented in section 7 (for paints) and section 8(for 3D printing).Lists of activities have been generated for the paints and 3D printing sectors along with information on theirrelease potential, key release determinant factors and measurements. Lists of commonly used nanomaterials,matrices and standards have also been compiled. These tables and a summary are provided in sections 5(paints) and 6 (3D printing) of this deliverable.These can be used by the other work packages in the course of their activities. The literature database fromthis deliverable for the two sectors also produced by this deliverable will be updated during the project for useby WP2-6.
