“…A granulometric analysis was conducted by sieving and pipette method. 17 The sediment samples were wet-decomposed following the 3050B method. 18 Quantification of the total elements Al, Cu, Cr, Fe, Pb, Ni and Zn in the digested samples were determined using an atomic absorption spectrophotometer with flame atomization (FAAS, AA240FS, Varian, Australia) or atomic absorption with graphite furnace atomization (AA280Z, Varian, Australia).…”

Seasonal concentrations of total, particulate and dissolved Al, Cu, Cd, Cr, Fe, Pb and Ni were analyzed in surface water and total metals in sediment samples from black and whitewater rivers within the Itacoatiara City, Central Amazon. Metals concentrations in water and sediment samples demonstrated that even though urbanization and agricultural practices are common in this region. Metal concentrations in sediments samples are acceptable regarding the recommended levels for protection of aquatic life. From this work, which is the first trace elements study in the main tributaries from Itacoatiara region, we conclude that metals are present in a particulate form, being easier to be transported to other aquatic bodies. During flooding periods an increase of Al, Fe and total organic compound (TOC) in almost water sampling points was observed.

“…A range of techniques has been employed for studying sediment provenance in coastal plains, with much of the focus on using not only mineralogy (Hein et al 2013; Kairyte and Stevens 2009;Lahijani and Tavakoli 2012;Wong et al 2013) but also multidisciplinary approaches including a combination of geochemical tracers, direct measurements and numerical modelling (Bernard et al 2013); radiometric analyses (Carvalho et al 2013); elemental and mineralogical analyses Fig. 1 Location of the Jagin study catchment in the Hormozgan province, southern Iran; geology, stream network, terrestrial source and target sediment sampling sites are shown (Pham et al 2018); synthesis of grain-size, clay mineralogy, geochemistry and mineral magnetism (Prizomwala et al 2014); geochemical properties (Rao et al 2015;Saitoh et al 2017), Nd-Sr isotopic ratios (Rosenbauer et al 2013); rare earth elements (REE) (Rao et al 2017); and optically stimulated luminescence (OSL) and thermoluminescence (TL) (Zular et al 2015).…”

“…We, hence, conclude that most of the fine-grained particles deposited in the Baltic Sea are provided by coastal and seabed erosion. Mineralogical studies confirm that fine-grained sediments deposited in major basins of the southern Baltic Sea (Arkona and Bornholm basins) and at the southern coast are mostly derived from glaciogenic material (till) eroded at the coast and at the seabed while riverine signatures are only dominant in sediments deposited close to river mouths (Gingele and Leipe, 1997;Kairytėand Stevens, 2009).…”

Erosion of carbonate-bearing sedimentary rocks may close the alkalinity budget of the Baltic Sea and support atmospheric CO2 uptake in coastal seas

High alkalinity values observed in coastal seas promote the uptake of CO2 from the atmosphere. However, the alkalinity budget of coastal areas and marginal seas is poorly understood, even though some of the recently observed alkalinity enhancement can be ascribed to riverine fluxes and anaerobic processes in shelf sediments. Here, we investigate the alkalinity budget of the Baltic Sea to identify previously unrecognized alkalinity sources. We quantify the generation of alkalinity and dissolved calcium (Ca) in this marginal sea applying simple mass balance calculations. Using this approach, we identify alkalinity and Ca sources of approximately 324 Gmol yr-1 and 122 Gmol yr-1, respectively, that cannot be ascribed to the riverine input. The magnitude of the Ca source suggests that a major fraction of the excess alkalinity (244 Gmol yr-1) is induced by the dissolution of calcium carbonate (CaCO3). A review of available field data shows that carbonate-bearing rocks at the coast and the seabed of the Baltic Sea are rapidly eroded and may provide sufficient CaCO3 to close the Ca budget. Hence, dissolution of eroded CaCO3 is the most likely source for the Ca enrichment observed in Baltic Sea water. This hypothesis is supported by mass accumulation rates of sediments derived from radioisotope data that are evaluated to derive a basin-wide rate of mud to muddy sand accumulation at the bottom of the Baltic Sea. The resulting value (139 Tg yr-1) exceeds current estimates of riverine particle fluxes into the Baltic Sea by more than one order of magnitude and confirms that rates of till erosion are sufficiently high to account for the Ca and most of the alkalinity excess in Baltic Sea water. Finally, we show that deliberate addition of CaCO3 to sediments deposited in the Baltic Sea could neutralize significant amounts of CO2 and help to achieve net-zero greenhouse gas emissions in the Baltic region.
