Table 1 Assignment of the test materials to various objectives based on the effects of selected material properties on ecotoxicity

From: Prioritising nano- and microparticles: identification of physicochemical properties relevant for toxicity to Raphidocelis subcapitata and Daphnia magna

Objective

Material

Influence of morphology

Toxic ion-releasing materials:

• Ag: fibre, flake, sphere

• Cu: fibre, sphere

Other materials (release of no ions or only nontoxic ions):

• TiO2: fibre, cube, sphere

• SiC: fibre, sphere, whisker

Influence of size and hybrid composition

Hybrids:

• IN_Y2O3 (µm-range)

• Ti64_SiC (µm-range)

Single components:

• IN718 (µm-range) + Y2O3 (nm-range)

• Ti64 (µm-range) + sSiC (nm-range)

Influence of size, reactivity, zeta-potential—monoconstituent materials

All materials including information from previous projectsa: TiO2, SiC, Y2O3, CeO2, Ag, Cu, CuO, ZnO

  1. aData for TiO2, CeO2, Ag, ZnO were taken from previous investigations; Hund-Rinke et al. [25], Kühnel et al. [35]
