Humic acid alleviates the toxicity of polystyrene nanoplastics in combination with their copper nanoparticle co-pollutants in <i>Artemia salina</i>
Summary
Researchers examined how humic acid, a natural organic substance found in soil and water, affects the toxicity of polystyrene nanoplastics combined with copper nanoparticles in brine shrimp. They found that humic acid reduced the harmful effects of these co-pollutants, likely by coating the particles and limiting their biological interactions. The study suggests that natural organic matter in the environment may help buffer some of the toxic effects of nanoplastic pollution.
Polystyrene nanoplastics (PSNPs) have become a ubiquitous environmental threat that can harm living organisms.
