Research at the Federal University of Western Pará (Ufopa) is focusing on the occurrence of cyanobacterial blooms, referred to as 'slime', in the beaches of the Tapajós River in Santarém. Led by researcher Fernando Abreu Oliveira, the study aims to identify environmental factors contributing to these blooms and assess their potential impact on water quality. The research addresses public health concerns and aims to inform local communities about safety measures regarding water use and environmental conservation.

Data collection was conducted between late 2025 and early 2026, specifically at popular beaches such as Ponta de Pedras, Alter do Chão, and Maracanã. The research team analyzed key indicators including chlorophyll-a, total phosphorus, and the Trophic State Index (IET) to assess nutrient levels in the water. Preliminary results indicated elevated concentrations of chlorophyll-a at certain locations, raising concerns about the implications for aquatic health and water safety for local recreational use.

This investigation not only highlights local environmental issues but also underscores the importance of scientific research in addressing potential health risks associated with water contamination. The findings aim to prompt a broader dialogue on water management and conservation in the region, emphasizing the need for effective strategies to monitor cyanobacterial blooms and their impact on human activity and biodiversity.
