Temporal observations of SPM were undertaken in cycles of neap-spring tides (highest values of 70,5 mg/L for spring tide and 33,1 mg/L for neap tide). The spatial distribution of SPM showed the highest value near the sewage input (75,9 mg/L). The concentrations of particulate elements decreased towards the open sea, with Ba and Zn presenting high concentrations not common of unpolluted ecosystems. Barium may have a geogenic origin since there are many barite deposits upstream. Zinc can be anthropogenic; however, these high concentrations could not be related to the shrimp farming located in the estuary, once they were also obtained upstreamAttribution 3.0 Brazilhttp://creativecommons.org/licenses/by/3.0/br/Material particulado em suspensãoSuspended particulate matterarticle10.21715/gb.v22i3.288
