Algal extracellular polymeric substances (algal-EPS) for mitigating the combined toxic effects of polystyrene nanoplastics and nano-TiO2 in Chlorella sp.
AI summary Read the abstract
This study found that algal extracellular polymeric substances can coat both polystyrene nanoplastics and titanium dioxide nanoparticles and reduce their combined toxic effects on the green alga Chlorella, suggesting that natural organic matter in marine environments can buffer combined nanoparticle toxicity.
Nanoplastic exposure inhibits growth, photosynthetic pigment synthesis and oxidative enzymes in microalgae: A new threat to primary producers in aquatic environment
AI summary Read the abstract
Scientists found that tiny plastic particles (nanoplastics) can seriously harm microalgae, the tiny plants that form the base of the ocean's food chain, by slowing their growth by up to 42%, reducing their ability to photosynthesize, and triggering stress damage inside their cells. Since these algae are eaten by small creatures that are eaten by bigger fish (eventually including the seafood we eat), this damage could ripple up the food chain and disrupt entire aquatic ecosystems. While this study looked at algae rather than humans directly, it adds to growing evidence that nanoplastic pollution, now found
Hetero-Aggregation of Nanoplastics with Freshwater Algae and the Toxicological Consequences: The Role of Extracellular Polymeric Substances
AI summary Read the abstract
Researchers studied how polystyrene and polylactic acid nanoplastics hetero-aggregate with the alga Chlorella vulgaris, finding that extracellular polymeric substances released by algae strongly influenced aggregation behavior and that aggregation altered the toxicity of nanoplastics.
Combined toxic impact of polystyrene nanoplastics and a flame retardant tetrabromobisphenol A (TBBPA) on freshwater algae Scenedesmus obliquus
AI summary Read the abstract
Scientists found that tiny plastic particles (nanoplastics) combined with a common flame retardant chemical (TBBPA) harm freshwater algae more than either pollutant does alone, slowing their growth and damaging their cells. Since algae form the base of aquatic food webs, this matters because these tiny organisms feed everything from small fish to the seafood we eventually eat, meaning pollution "teamwork" in our waterways could have ripple effects up the food chain and, ultimately, onto our plates.
Algal EPS modifies the toxicity potential of the mixture of polystyrene nanoplastics (PSNPs) and triphenyl phosphate in freshwater microalgae Chlorella sp.
AI summary Read the abstract
Researchers found that a natural substance produced by algae (extracellular polymeric substances, or EPS) can reduce the toxic effects of nanoplastics combined with a flame retardant chemical in freshwater. The EPS coated the nanoplastics and reduced their ability to harm algal cells. This natural protective mechanism could play an important role in how aquatic ecosystems buffer against the combined threat of microplastics and chemical pollutants.
