Descripción
Sediment traps deployed in Buenos Aires sewage outfall area collected a substantial amount of material (average mass flux 22 ± 12 g cm² year⁻¹) with very high metal concentrations, mostly in the range of hazardous exposition for organisms (Zn: 138–671, Cu: 41–273, Cr: 44–255 and Pb: 26–260 μg g⁻¹). The combination of high mass fluxes and concentrations results in huge metal fluxes (0.005–0.7 to 3.6–31 g m⁻² day⁻¹ for minor elements and Fe, respectively). Metal concentrations were correlated to the total mass flux and total organic carbon but with different trends for redox-sensitive Fe and Mn (negative) and anthropogenic elements (positive). This reflects the key role of organic discharges promoting anoxia with Fe and Mn evasion, and also contributing toxic metals.
