However, Si doping alters the bandgap, leading to a transition from semiconductor to metallic properties. Moreover, bi-directional tensile and compressive strains significantly modify the electronic and optical properties. Optical analyses indicate that compressive strain significantly increases the absorption coefficient, reflectance, and energy loss of the material in the infrared and visible regions, while tensile strain significantly increases the absorption coefficient, reflectance, and energy loss of the material in the ultraviolet region.

Therefore, to determine the impact of SiO<sub>2</sub> NPs and their multigenerational toxicity, an established model of nano-ecotoxicology, <i>Caenorhabditis elegans</i> was employed. First, the impact of SiO<sub>2</sub> (0.2–0.3 µm, bulk) and SiO<sub>2</sub> NPs (40 nm) exposure on the vital processes namely survival, growth, behavior, and reproduction were determined. Worms showed a concentration-dependent response to SiO<sub>2</sub> NPs exposure, while no impact on exposure to bulk SiO<sub>2</sub>. The transcription factor (<i>daf- 2</i>) and vitellogenin (<i>vit- 2</i> and <i>vit- 6</i>) expression were downregulated, while oxidative stress and germline apoptosis increased in worms exposed to SiO<sub>2</sub> NPs. At environmentally relevant concentrations of SiO<sub>2</sub> NPs caused a significant impact on the reproductive output of worms. To determine the multigenerational impact on reproduction, worms were exposed for 11 generations and found a decline in progeny count across all the generations screened. When the worms were removed from exposure after 6 generations, it took 5 generations to regain their original vitality. This study indicates that exposure to the SiO<sub>2</sub> NPs has a cumulative impact on the reproductive output across generations.

However, the widespread discharge of municipal sewage, industrial solvents, agrochemicals, heavy metals, and nanoparticles threatens aquatic ecosystems. While nanomaterials hold promise for pollution remediation, their high surface reactivity and small size facilitate biotransformation, increasing their environmental interactions and disrupting aquatic food webs, particularly in tropical and subtropical regions. This review examines the adverse effects of engineered nanoparticles (ENPs) on aquatic life, emphasizing their bioaccumulation in species. Titanium dioxide nanoparticles exhibit bioaccumulation rates of up to 86%, whereas copper nanoparticles accumulate at only 0.9 ppb. Affected organs include the gills, brain, and lungs, highlighting nanoparticle contamination’s widespread impact. Biofilms enhance nanoparticle adsorption and pollutant transport. This study introduces the bioaccumulation index (BAI), improving bioaccumulation assessment over conventional methods. Findings stress the need for regulatory frameworks, sustainable nanotechnology, and advanced monitoring to reduce environmental risks. Future work should focus on long-term toxicity studies, eco-friendly designs, and mitigation strategies.
