The use, production, and disposal of engineering nanomaterials (ENMs), including
graphene-related materials (GRMs), raise concerns and questions about possible adverse effects
on human health and the environment, considering the lack of harmonized toxicological data on
ENMs and the ability of these materials to be released into the air, soil, or water during common
industrial processes and/or accidental events. Within this context, the potential release of graphene
particles, their agglomerates, and aggregates (NOAA) as a result of sanding of a battery of graphenebased polyester resin composite samples intended to be used in a building was examined. The
analyzed samples were exposed to different weathering conditions to evaluate the influence of the
weathering process on the morphology and size distribution of the particles released. Sanding
studies were conducted in a tailored designed sanding bench connected to time and size resolving
measurement devices. Particle size distributions and particle number concentration were assessed
using an optical particle counter (OPC) and a condensation particle counter (CPC), respectively,
during the sanding operation. A scanning electron microscope/energy dispersive X-ray (SEM/EDX)
analysis was performed to adequately characterize the morphology, size, and chemical composition
of the released particles. A toxicity screening study of pristine and graphene-based nanocomposites
released using the aquatic macroinvertebrate Daphnia magna and relevant human cell lines was
conducted to support risk assessment and decision making. The results show a significant release
of nanoscale materials during machining operations, including differences attributed to the % of
graphene and weathering conditions. The cell line tests demonstrated a higher effect in the human
colon carcinoma cell line Caco2 than in the human fibroblasts (A549 cell line), which means that
composites released to the environment could have an impact on human health and biota. [-]
