Glitter's Glimmering Toll: Rio Carnival's Eco-Crisis

Rio de Janeiro's world-famous Carnival leaves behind more than just memories; it creates a significant environmental problem with glitter pollution.

During the recent Carnival, which concluded on Wednesday, 2026-02-19, a massive amount of plastic glitter adorned revelers, contributing to microplastic contamination on the city's seafront, particularly along Flamengo beach.

A study conducted by researchers from the Federal University of the State of Rio de Janeiro (Unirio) found a dramatic increase in microplastics during the festival. Samples revealed glitter as the main culprit, with concentrations infinitely higher than before or after the event.
