Zebrafish Insights into Nanomaterial Toxicity: A Focused Exploration on Metallic, Metal Oxide, Semiconductor, and Mixed-Metal Nanoparticles
This review summarizes research on how various nanomaterials, including nano-sized plastics, affect zebrafish, which are commonly used as stand-ins for studying human health effects. Exposure to nanomaterials caused developmental defects, organ damage, behavioral changes, and reproductive problems in zebrafish. These findings help scientists understand the potential health risks of nanomaterial exposure to humans and the environment.
Multi biomarker approach to assess manganese and manganese nanoparticles toxicity in Pangasianodon hypophthalmus
Researchers exposed catfish (Pangasianodon hypophthalmus) to manganese and manganese nanoparticles at various concentrations, finding that both forms — especially the nanoparticle form — caused significant oxidative stress, immune disruption, neurochemical changes, and liver and gill damage, with effects worsened at higher water temperatures. The study shows that even essential minerals become toxic in their nanoparticle form or at elevated concentrations, particularly in a warming climate.

This systematic review covers nanoplastic toxicity toward freshwater organisms, examining both conventional and bioplastic nanoplastics, and finds that size, shape, and surface chemistry all influence toxicity across a range of invertebrate and vertebrate freshwater species.
Bioaccumulation assessment of nanomaterials using freshwater invertebrate species
Researchers reviewed how freshwater invertebrates such as amphipods and bivalves can be used to test whether engineered nanomaterials accumulate in living organisms, finding that amphipods are the most suitable test species because they can be exposed through both water and food. The study proposes a tiered framework for classifying nanomaterials as bioaccumulative or not, which could reduce the need for vertebrate animal testing.
Emerging trends in nanoparticle toxicity and the significance of using Daphnia as a model organism
Researchers reviewed why the freshwater crustacean Daphnia is a valuable model organism for nanoparticle toxicity testing, summarizing how nanoparticle size, charge, and surface chemistry influence toxicity in Daphnia and highlighting key knowledge gaps in nanoplastic environmental risk assessment.
A holistic approach to assess the toxic behaviour of emerging nanomaterials in aquatic system
Not relevant to microplastics — this book chapter reviews how emerging nanomaterials behave at nano-bio-eco interfaces, discussing toxicity, fate, and exposure potential in aquatic systems without a specific focus on plastic particles.
Prioritising nano- and microparticles: identification of physicochemical properties relevant for toxicity to Raphidocelis subcapitata and Daphnia magna
Ecotoxicity data for 36 nano- and microparticles of diverse inorganic compositions were generated and used to develop a prioritization framework for identifying which advanced materials pose the greatest human and environmental hazard. The approach provides a practical tool for risk-based regulation of the expanding universe of engineered nano- and microparticles.
Identifying Knowledge Gaps on Ecotoxicological Assessment of Micro/Nanoplastics with Aquatic Keystone Species
This review identifies knowledge gaps in the ecotoxicological assessment of micro- and nanoplastics across aquatic and terrestrial organisms, highlighting inconsistencies in particle characterization, exposure concentrations, and endpoint selection that limit cross-study comparisons and risk assessment.
