“…In the media without DOC, the particles are positively charged (Table S1, Supporting Information). As we observed in our previous study (Arenas-Lago et al, 2019), an increase in the concentration of Ca 2+ /Mg 2+ increases the positive charge of the Cu 0 -ENPs (Table S2, Supporting Information) due to specific interactions of Ca 2+ with the Cu 0 -ENPs (Monikh et al, 2018). Due to the repulsive electrostatic force between the particles, Cu 0 -ENPs remain stable against aggregation and, consequently, dissolution of the Cu 0 -ENPs increases.…”

“…After 1 h, the particle D h was between 278 nm and 425 nm. The averaged zeta potential value of about −3.4 ± 0.4 mV was measured by electrophoretic mobility and indicates that the particles are prone to aggregation as the value of the zeta potential is close to zero (Monikh et al, 2018). The obtained TEM picture showed an immediate aggregation of the particles (Fig.…”

“…Concentrations of CaCl 2 and MgSO 4 used to set the ionic strength were selected in a fixed content molar ratio of 4:1 (Ca 2+ /Mg 2 + ) according to the method reported by Arenas-Lago et al (2019). A ratio of 4:1 (Ca 2+ /Mg 2+ ) is mimicking natural conditions, as reported in the literature (Abdolahpur Monikh et al, 2018). We used either 0.1 M NaOH or 0.1 M HCl to change the pH of the solution.…”

“…As a consequence, the environmental release of these ENPs upon production, manufacturing and application is practically inevitable (Bihan et al, 2013). This has generated an increase in the concern about the behaviour and fate of these ENPs in the environment, which are still not well-known, although considerable information regarding these topics have been generated during the last years (Chen et al, 2016;Ehret et al, 2014;Monikh et al, 2018).…”

“…Thus, it is critical to understand the aggregation and dissolution processes of ENPs and the influence of the different physicochemical parameters on them to their influence on their uptake and toxicity in the aquatic environment (Keller et al, 2010). For example, NOM can stabilise particles and prevent their aggregation in suspension (Abdolahpur Monikh et al, 2018). By increasing the stability of the ENPs, a large surface area of the ENPs is available for dissolution (Wang et al, 2015;Wang et al, 2011;Arenas-Lago et al, 2019).…”

UV‐dependent freshwater effect factor of nanoscale titanium dioxide for future life cycle assessment application

Environmental impacts of nanoscale titanium dioxide (TiO 2 ) should be assessed throughout the lifetime of nanoparticles (NPs) to improve the state of knowledge of the overall sustainability. Life cycle assessment (LCA) has been previously recognized as a promising approach to systematically evaluating environmental impacts of NPs. As a result of their unique nanospecific properties, characterization factors (CF) were previously used for compensating the release and potential impacts of TiO 2 NPs. However, because TiO 2 NPs are known to generate reactive oxygen species and elicit toxicity to freshwater organisms, the lack of adequate UV-dependent effect factors (EFs) remains a major shortcoming when addressing their life cycle impacts. To complement the LCA of TiO 2 -NPs-enabled products under their specific applications, we recapitulated the freshwater toxicity of TiO 2 NPs and then modeled in USEtox to determine trophic level EF ranges under UV and non-UV exposure conditions. Results indicate that EFs derived for non-UV exposure were 52 (42.9-65) potentially affected fraction (PAF) m 3 /kg, and combined toxicity data derived EFs were 70.1 (55.6-90.5) PAF m 3 /kg. When considering only the UV-induced exposure condition, the modeled EF increased to 500 (333-712) PAF m 3 /kg. Our work highlights that case-dependent EFs should be considered and applied to reflect more realistic ecological impacts and illustrate comprehensive life cycle environmental impacts for nanoenabled products.
