“…Elements may accumulate in the different geochemical layers of the sediment mainly through adsorption [16]. Thus, this sediment "memory" can provide snapshots of the aquatic ecosystems over time, recording information of environmental impact episodes and accumulating chemical species either used or produced by anthropogenic activities [17,18]. Sediment-trapped elements are not inert and may return to the water column through different pathways, such as resuspension events caused by wind or wave actions, dredging, bioturbation, biological transformations (e.g.…”

“…impacts are a concern, as local soil, mineral dust, heavy equipment emissions and combustion sources and resuspension of particulate matter (PM) may all contribute to PM in surrounding areas [22]. High metal content in APM was observed by Mimura et al [18] near a zinc mining industry, established in Juiz de Fora since 1980.…”

Health risk assessment of different metals (Cd, Cr, Fe, Mn and Zn) was evaluated in 12 street dust samples (SD) collected in Juiz de Fora and Congonhas cities, Southeast Brazil, from May to July 2017. Quartz, hematite, magnesium and aluminum silicate were found in Congonhas' samples, while quartz, hematite, andaluzite, diopside, dolomite and calcite phases have been found in Juiz de Fora's samples. The main elements observed in the samples were Al, Fe, O and Si, elements such as Ca, K, Mg, Na and Ti were found in minor concentrations. The major mineral phases observed in SD samples by MLA were iron oxides and hydroxides, quartz, clay compounds and many phases containing the Al element, which are in accordance with the XRD analysis characterization. Analytes were detected in the following order: Fe> Zn> Mn> Cr> Cd, except for Mn> Zn in the Congonhas samples. The Zn contents found in some samples were higher than prevention value for industrial areas (2000 mg kg-1). The metals Cd (56 to 90%) and Zn (37 to 59%) showed high gastrointestinal bioaccessibility. The Cr and Fe analytes presented low solubility ranging from 10 to 18% and from 8 to 10%, respectively. It was verified that Cd and Zn presented non-carcinogenic risk through dermal, ingestion and inhalation contact for the most samples studied. However, non-carcinogenic risk factor (HQ) obtained for Zn in all samples collected were greater than the limit set by USEPA. No carcinogenic risk was observed for Cd and Cr in the investigated samples.

The Três Marias Reservoir is the ninth-largest reservoir in Brazil, becoming crucial for national strategic development.However, many anthropic activities may affect the sediment quality, promoting the need for a proper environmental assessment. This research appraised the seasonal in uences on the Três Marias Reservoir's sediments geochemistry, elucidating possible anthropogenic impacts. The concentrations of Mg,
