Answer all questions below and test your knowledge.

1
A 2024 review in 'Nature Nanotechnology' highlighted a major shift in assessing nanomaterial risk. What is the core principle of the 'Safe-and-Sustainable-by-Design (SSbD)' framework that distinguishes it from traditional risk assessment?
Question 1
2
In assessing the long-term fate of metal-oxide nanoparticles in soil, which physicochemical transformation is considered most critical for reducing bioavailability and acute toxicity of ions like Zn2+ or Cu2+?
Question 2
3
The concept of 'Trojan horse' effect in nanotoxicology specifically refers to which mechanism?
Question 3
4
Which advanced analytical technique, coupled with spatiotemporal modeling, is now considered essential for quantifying the transformation kinetics and heteroaggregation of engineered nanoparticles in complex natural waters?
Question 4
5
When evaluating the net climate impact of a nano-enabled product (e.g., a nanocellulose composite), a comprehensive Life Cycle Assessment (LCA) must account for a potential 'burden shift.' What does this term most accurately describe?
Question 5
6
According to recent studies on nanoplastic-nanomaterial interactions, what is a hypothesized significant ecological consequence when engineered nanoparticles (e.g., TiO2) heteroaggregate with nanoscale plastic debris in aquatic systems?
Question 6
7
In the context of regulatory ecotoxicity testing for nanomaterials, what is the primary scientific rationale for advocating 'chronic, low-concentration, multi-generational' studies over standard acute toxicity tests?
Question 7
