Description
Alex da Silva de Freitas and co-authors check a Brazilian lagoon's mud for modern pollutants in a 2026 study. Maricá Lagoon, near Rio de Janeiro, takes steady pressure from surrounding settlement, and its sediments can store drugs, plastic additives, and hormone-like chemicals. The team sampled seven fixed spots in the dry seasons of 2021 and 2023 and asked whether the pollution picture changed between years.
Lab analysis found the plastic additive BPA most often, then two industrial phenols, plus steroid hormones and drug traces. One station stood out, holding nine of the twelve target compounds, a clear local hotspot. A yeast test confirmed hormone-like activity in selected samples. The study frames sediments as a memory of the lagoon's chemical load.
