Microplastics Decrease the Toxicity of Sulfamethoxazole to Marine Algae (Skeletonema Costatum) at the Cellular and Molecular Levels

Microplastics decrease the toxicity of sulfamethoxazole to marine algae (Skeletonema costatum) at the cellular and molecular levels

AI summary · Read the abstract

Researchers investigated the combined toxicity of the antibiotic sulfamethoxazole and five types of microplastics on the marine alga Skeletonema costatum. They found that certain microplastics actually decreased the toxicity of the antibiotic by adsorbing it, creating a protective "shelter" effect, though polystyrene combined with the antibiotic caused higher oxidative stress. The study suggests that microplastics can alter the bioavailability and toxicity of co-occurring pollutants in marine environments through adsorption interactions.
