The problems of heavy metals in the environment, environmental toxicity, and the uses of water.   Method: Techniques such as bibliographic and documentary research; information inventories; collection and analysis of bottom sediment samples. Collections were at 3 (three) points at the mouth of the channel, one on the channel bed and one on the Sérgio Arruda Bridge. An Atomic Absorption Spectrophotometer from the Atomic Absorption and Bioprospecting Laboratory (LAAB).   Results and conclusion: Observed that Cd, Pb, Cr and Ni presented values ​​above those stipulated by legislation. And that seasonal variation contributes to the increase in the concentration of the metals Cd, Cr, Cu, Mn and Ni in the bottom sediment.   Implications of the research: This study will contribute to public policy measures, helping decision-making for environmental improvement in the municipality of Macapá-AP.   Originality/value: This research is of socio-environmental and scientific importance, as it evaluates the concentration of heavy metals and associates it with the lack of environmental sanitation and rainfall in the region.
