Considering safe and sustainable by design alternatives-Environmental hazards of an agriculture nano-enabled pesticide to non-target species.

Nanopesticides (Npes) offer improved efficacy compared to their conventional forms while reducing the usage/application rates, hence being more sustainable options. However, there is still a knowledge gap on the Npes environmental impacts. To support the safety of nano-enabled pesticides, the present study aimed at assessing the toxicity of the commercial Npe NUCOP-M and the active substance copper oxychloride, using the ecotoxicological soil model Enchytraeus crypticus and LUFA 2.

On the lifespan of - impact of iron (nanomaterial and salt) on aging.

Iron oxide nanomaterials (FeO NMs) have important biomedical and environmental applications, e.g. drug delivery, chemotherapy, magnetic resonance imaging contrast agents, etc.

Soil type dependent toxicity of AgNM300K can be predicted by internal concentrations in earthworms.

A continuous challenge in nanotoxicology is the interaction of nanoparticles with the soil components. In the present study, we compare the toxicity of silver nanoparticles (AgNM300K) on earthworms across 4 different soils, exploring which among the total-, soil solution-, or worm tissue-Ag-concentrations that enables the best prediction of toxicity across the soils. We exposed the earthworm Eisenia fetida to AgNM300K for 56 days to assess survival, reproduction, and bioaccumulation.

Machine Learning Allowed Interpreting Toxicity of a Fe-Doped CuO NM Library Large Data Set─An Environmental In Vivo Case Study.

The wide variation of nanomaterial (NM) characters (size, shape, and properties) and the related impacts on living organisms make it virtually impossible to assess their safety; the need for modeling has been urged for long. We here investigate the custom-designed 1-10% Fe-doped CuO NM library. Effects were assessed using the soil ecotoxicology model (Oligochaeta) in the standard 21 days plus its extension (49 days).

Governance of advanced materials: Shaping a safe and sustainable future.

The past few decades of managing the uncertain risks associated with nanomaterials have provided valuable insights (knowledge gaps, tools, methods, etc.) that are equally important to promote safe and sustainable development and use of advanced materials. Based on these insights, the current paper proposes several actions to optimize the risk and sustainability governance of advanced materials.
