ClearRevealing the Selenium-Mediated Regulatory Mechanisms of P. stratiotes in Response to Nanoplastics Stress from Multiple Perspectives of Transcriptomics, Metabolomics, and Plant Physiology
Scientists found that tiny plastic particles (nanoplastics) seriously damage water plants by disrupting their ability to make food from sunlight and causing harmful stress inside their cells. However, when researchers added selenium (a natural mineral) to the water, it helped protect the plants from plastic damage by boosting their natural defense systems. This research could help us clean up plastic pollution in lakes and rivers, which is important since these water sources can affect human health through drinking water and food chains.
Nano-selenium ameliorates microplastics-induced injury: Histology, antioxidant capacity, immunity and intestinal microbiota of grass carp (Ctenopharyngodon idella)
Researchers tested whether nano-selenium supplements could protect grass carp from damage caused by polystyrene microplastics. They found that nano-selenium reduced the tissue damage, oxidative stress, and immune suppression caused by microplastic exposure, and helped restore healthy gut bacteria. The study suggests that dietary nano-selenium may be a practical strategy for protecting farmed fish from the harmful effects of microplastic pollution in aquatic environments.
Insights into the molecular response of Dioithona rigida to selenium nanoparticles: de novo transcriptome assembly and differential gene expression analysis
Researchers exposed a marine copepod species to selenium nanoparticles and used genetic analysis to understand the molecular-level effects. They found significant changes in genes related to DNA repair, oxidative stress response, and cell membrane function. The study matters because copepods are a key link in marine food chains, so contaminant effects on these tiny organisms can have ripple effects through the ecosystem and ultimately affect the seafood humans consume.

Selenium toxicity in fishes: A current perspective
This review examines how selenium, a naturally occurring element released by mining and industrial activity, builds up in fish to toxic levels and damages their reproduction, growth, and organ function. While the study focuses on fish toxicity rather than microplastics, it illustrates how environmental pollutants bioaccumulate through aquatic food chains and can ultimately reach humans who consume contaminated seafood.
Effect of Different Dietary Selenium Sources on Growth Performance, Antioxidant Capacity, Gut Microbiota, and Molecular Responses in Pacific White Shrimp Litopenaeus vannamei
Researchers investigated how different dietary selenium sources affect growth, antioxidant capacity, and gut microbiota in Pacific white shrimp, finding that selenium nanoparticles and selenium yeast provided superior antioxidant protection compared to inorganic selenium.
Unveiling the underlying mechanism: Metabolic reprogramming and oxidative stress mediate nanoplastic-induced hepatotoxicity in a freshwater fish (Pseudorasbora parva)
Scientists studied how tiny plastic particles (nanoplastics) affect fish livers and found that the smallest particles (80 nanometers) caused the most damage by disrupting the body's ability to fight harmful chemicals and process energy. The smallest plastic particles were especially harmful because they damaged the fish's natural defense systems and changed how their cells make energy. While this study was done in fish, it raises concerns about how these tiny plastic particles in our environment might also harm human health.

Environmentally derived nanoplastics induce oxidative and genotoxic responses in gilthead seabream (Sparus aurata)
Scientists created tiny plastic particles from real ocean pollution and exposed fish to them for four days. The plastic particles didn't kill the fish, but they damaged the fish's DNA and caused harmful stress inside their cells. This matters because these same tiny plastics are building up in our oceans and food chain, potentially affecting the seafood we eat.
Microplastic-induced NAFLD: Hepatoprotective effects of nanosized selenium
This study found that polystyrene microplastics caused nonalcoholic fatty liver disease in mice by disrupting fat metabolism and triggering oxidative stress, but selenium nanoparticles derived from a yak-sourced bacterium significantly prevented this damage. The microplastics suppressed two key protective pathways in the liver, while the selenium nanoparticles activated those same pathways to counteract the harm. These findings suggest that microplastic exposure may contribute to liver disease in humans and point to selenium-based supplements as a potential protective strategy.
