Sources, mobility, and accumulation of major and trace elements in sediments: implications for environmental quality and management of an urbanized tropical lake (Brasília, Brazil)

Puntos clave

• Accumulation of trace elements and major elements indicates a concerning level of pollution in sediments.
• The analysis showed elevated levels of specific trace elements, such as lead and cadmium, in sediments sampled from the lake.
• Assessment of sediments using environmental quality standards highlighted the need for improved lake management practices.
• Results imply that further monitoring and management strategies are needed to address sediment pollution and protect the ecosystem.
