In the Amazon rainforest, methylmercury (MeHg) is easily biomagnified and bio-accumulated in the aquatic food chain. This unique biome has been studied for occupational and environmental issues related to human health and contamination through fish consumption; however, wildlife studies have not yet addressed fish-eating birds. Different species of birds categorized by foraging strategies and life-stages were studied in the Madeira River Basin (Western Amazon rainforest).

- The Madeira River is facing environmental challenges due to artisanal gold mining, deforestation, and related activities, leading to increased mercury levels in the ecosystem.
- A study surveyed total and methylmercury exposure in two communities along the river, analyzing samples from 137 individuals, including adults and children.
- Women from Lago Puruzinho had significantly higher mercury levels in blood and hair compared to those from São Sebastião do Tapurú, with a strong correlation between mothers' and children's hair mercury levels.
