Researchers studied sand at Flamengo Beach in Rio de Janeiro during 2024. They collected samples before, during and shortly after Carnival, and again eight months later. The aim was to see how the event changed particle levels in the sand.
Results showed plastic fragments, including glitter, made up the majority of microplastics. Particle levels stayed higher for several days after Carnival ended. Scientists warn that these particles can move to the nearby ocean and be eaten by animals, or harm plants.
The study mentions alternatives to conventional glitter and notes a bill in Brazil would ban plastic and metal glitter.
