“…Elements like Cu may play a pivotal role in bioavailability and the residence time of aromatic DOM through a watershed from the upland soils to the hyporheic zone sediments (Liu et al., 2019; Salomão et al., 2021). Such relationships are subject to a myriad of complex interactions, including the impact of human activities (urbanization, mining, agriculture) which can lead to increases in Cu concentrations in streams compared to the surrounding soils (Lin et al., 2022; Wang et al., 2021).…”

The hyporheic zone is a hotspot for biogeochemical cycling where interactions with mineral metals preserve the release and biodegradation of organic matter (OM). A small fraction of OM can still be exchanged between localized sediments and the overlying water column, and recent evidence suggests there exists a longitudinal structuring in sediment dissolved OM (DOM) chemistry across the continental United States (CONUS). In this study, we tested a hypothesis that water extractable sediment DOM chemistry could be explained by sediment metal contents and integrative watershed scale features at the CONUS scale. Crowdsourced samples were characterized for high resolution mass spectrometry and coupled with sediment metals determined via x‐ray fluorescence as well as with land cover and soil elemental information obtained from national databases. Our results highlight weak relationships between DOM chemistry and elemental composition at the CONUS scale indicating limited transferability of organo‐metal linkages into multi‐scale hydrobiogeochemical models.

“…De color amarillo y azul se encuentran las zonas que registran concentraciones en menor proporción y están ubicadas en el estuario exterior del golfo. En Malasia un estudio realizado a lo largo del río Mamut muestra cómo las concentraciones de metales potencialmente nocivos disminuyen entre un 20-97% disminuyen desde la posible fuente hacia afuera [18]. Se mencionan diversos factores como la precipitación de metales al aumentar el pH del río, el aumento del caudal, absorción de metales, y solubilidad de minerales en los terrenos cercanos.…”

The present study aims to contribute to the understanding of the current situation of heavy metak pollution in the Gulf of Guayaquil (GG). The GG is an area where multiple productive sectors operate, and most of the country's mangroves are located. The research objective is to evaluate the geochemical behaviour of heavy metals in the gulf by estimating the degree and distribution of pollution in the period 2019-2021 using monthly chemical reports of sediments provided by the company CGU S.A. We analyzed concentrations of As, Cd, Cu, Pb and Zn at 7 points in the GG, determined accumulation zones and the degree of pollution usisng indexing methods, correlated the data, and performed cluster analysis to determine possible sources. Our findings showed an accumulation and pollution of Cu and Cr in 3 estuaries of the city of Guayaquil. The major pollution detected corresponds to 2020 data. The areas with higher accumulation exhibited a higher sediment contamination load. The ecological risk level remained low in all periods. Possible contamination sources are associated with anthropogenic activity from different productive sectors around the gulf.
