Mangroves can be considered as biogeochemical reactors along (sub)tropical coastlines, acting both as sinks or sources for trace metals depending on environmental factors. In this study, we characterized the role of a mangrove estuary, developing downstream a densely populated megacity (Ho Chi Minh City, Vietnam), on the fate and partitioning of trace metals. Surface water and suspended particulate matter were collected at four sites along the estuarine salinity gradient during 24 h cycling in dry and rainy seasons. Salinity, pH, DO, TSS, POC, DOC, dissolved and particulate Fe, Mn, Cr, As, Cu, Ni, Co and Pb were measured. TSS was the main trace metals carrier during their transit in the estuary. However, TSS variations did not explain the whole variability of metals distribution. Mn, Cr and As were highly reactive metals while the other metals (Fe, Ni, Cu, Co and Pb) presented stable log K values along the estuary. Organic matter dynamic appeared to play a key role in metals fractioning. Its decomposition during water transit in the estuary induced metal desorption, especially for Cr and As. Conversely, dissolved Mn concentrations decreased along the estuary, which was suggested to result from Mn oxidative precipitation onto solid phase due to oxidation and pH changes. Extra sources as pore-water release, runoff from adjacent soils, or aquaculture effluents were suggested to be involved in trace metal dynamic in this estuary. In addition, the monsoon increased metal loads, notably dissolved and particulate Fe, Cr, Ni and Pb.

“…POC (10,135 t y À1 ) and PON (977 t y À1 ) fluxes present the same seasonal trend, with the highest percentage transported in the rainy season. The seasonal variation, observed in the transport of these chemical species associated with the FSS of the Sorocaba River, was influenced more by the temporal variability of discharge and FSS concentrations, than by their concentration variations in the dry and rainy seasons, as already reported in the literature for other basins (Kucuksezgin et al, 2008;Radakovich et al, 2008;Song et al, 2010;Wen et al, 2013).…”

“…Similarly, according to Zhang and Liu (2002), in many studies it was agreed that 0.5 < EF < 1.5 are indicatives of natural contribution and for EF > 1.5 a significant percentage of the element comes from other sources, such as the biota and anthropogenic pollution. Fixed values for EF have been also used to differentiate natural contributions from anthropogenic sources, such as 1.0 (Miller et al, 2007;Viers et al, 2009), 1.5 (Harikumar and Jisha, 2010) and 2.0 Probst, 2006a, 2006b;Mukherjee, 2014;Roussiez et al, 2013;Wen et al, 2013;Woitke et al, 2003). In our study it was assumed that for EF 1 the contributions of the trace element studied are natural (soil and rocks erosion processes) and for EF > 1 the contributions of the trace elements can be related to natural and anthropogenic sources (domestic and industrial effluents).…”

Approximately 40% of the volume of domestic sewage generated in the São Paulo State is untreated and released into water bodies, causing serious pollution problems that affect the water quality and especially the suspended sediments transported by rivers. Thus, this paper investigates the seasonal influence on the origin and fluxes of Cu, Co, Cr, Zn, Cd, Ni, Sc and particulate organic matter (POM) in sediments transported by a disturbed watershed in the São Paulo State, i.e. the Sorocaba River basin. POM was characterized using particulate organic carbon, particulate organic nitrogen, C:N ratio and δC and δN stable isotopic composition. Eight sample collections of fine suspended sediments (FSS) were carried out at the mouth of the Sorocaba River from July 2009 to May 2010. During the study period, the discharge rate followed the seasonal variation trend of the past 25 years. Zn was the most abundant trace element in the FSS, followed by Cr, Cu, Ni, Co, Sc and Cd. There was a higher concentration of trace elements during the dry season, except for Sc and Co, which did not vary seasonally. The POM showed the same trend, with higher concentrations during the dry season. The calculated enrichment factors and geoaccumulation index indicated that most of the trace elements are of geogenic origin, except for Zn, which showed significant anthropogenic contributions (55%). The elemental and isotopic analysis of C and N and C:N ratio indicated that the anthropogenic origin of POM found in the FSS is related mainly to domestic sewage (97%), while the significant correlation found between the concentrations of Zn and POM indicates that the main anthropogenic source of Zn is related to this domestic sewage. The FSS load transported during the study period was of 373,194 t y, of which 87% occurred during the rainy season.

Numerous natural and anthropogenic processes in a watershed produce the geochemical composition of a river, which can be altered over time by snowmelt and rainfall events and by built infrastructure (i.e., dams and diversions).Trace element concentrations coupled with isotopic ratios offer valuable insights to disentangle the effects of these processes on water quality. In this study, we measured a suite of 40+ trace and major elements (including As,
