“…A recent 24 h study on C. gigas (pacific oysters) demonstrated the paradoxical effects of various types of GO. GO (e.g., 0.2–8 μm and 30% oxygen content) at 0.1 mg/L was found to worsen copper-mediated embryo-larval toxicity while rGO (with similar dimensions to GO but with 16.8% oxygen content) comparatively mitigated the effects by way of decreasing copper bioavailability …”

Heterocypris incongruens can also be used according to ISO 14371 for the determination of lethal and sublethal effects of contaminated sediments after 6 days of exposure.…”

Two-dimensional (2D) materials have attracted tremendous interest ever since the isolation of atomically thin sheets of graphene in 2004 due to the specific and versatile properties of these materials. However, the increasing production and use of 2D materials necessitate a thorough evaluation of the potential impact on human health and the environment. Furthermore, harmonized test protocols are needed with which to assess the safety of 2D materials. The Graphene Flagship project (2013−2023), funded by the European Commission, addressed the identification of the possible hazard of graphene-based materials as well as emerging 2D materials including transition metal dichalcogenides, hexagonal boron nitride, and others. Additionally, socalled green chemistry approaches were explored to achieve the goal of a safe and sustainable production and use of this fascinating family of nanomaterials. The present review provides a compact survey of the findings and the lessons learned in the Graphene Flagship.
