Summary

Researchers developed a novel chemiluminescence-based detection platform for polystyrene microplastics by repurposing DEHP-rich PVC waste and spent copper catalysts, creating carbon-based composites that generate a measurable light signal quenched by microplastic particles, enabling sensitive detection across a wide concentration range in real water samples.
