Abstract Population growth and urbanization have led to critical environmental challenges worldwide. Chemical pollutants, especially Potentially Toxic Elements (PTEs) such as Cd (Cadmium), Cu (Copper), Zn (Zinc), Al (Aluminum) and Mn (Manganese), as well as macroelements like P (Phosphorus), affect physicochemical and ecological parameters, posing risks to both human health and biodiversity.

ABSTRACT Manaus has the Tarumã-Açu and Tarumã-Mirim urban basins. These are part of a complex network of basins that form in the region and can influence water quality throughout the Amazon region and, consequently, Brazil. The objective of this study was to comparatively evaluate the water quality in the Tarumã-Açu and Tarumã-Mirim basins. Samples were collected at ten georeferenced points.
