Metal partitioning and speciation in a mining-impacted estuary by traditional and passive sampling methods

Diffusive gradients in thin films for the measurement of labile metal species in water and soils: a review

“…Finally, few studies have been conducted trying to understand the relationships between DGT determinations of trace elements and their absorption by different organisms; Cd, Cu, Fe, Mn, Ni, Pb, Zn Warnken et al (2009) As, Cd, Cr, Cu, Ni, Pb, Sb, Se Devillers et al (2017b) Cd, Cr, Co, Cu, Mn, Ni, Pb, Zn Uher et al (2013, Dabrin et al (2016) Al, As, Cr, Co, Cu, Mn, Pb, Sn, Zn Larner et al (2006) Al, Cd, Co, Cr, Cu, Fe, Ni, Pb, Zn Liu et al (2013a) Al, Cd, Co, Cu, Fe, Mn, Ni, Pb, Zn Warnken et al (2007, Sherwood et al (2009) Al, Cr, Co, Cu, Mn, Ni, Pb, U, Zn Agnelli et al (2014) Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Zn Dragun et al (2008 10+ elements Al, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Zn Díaz et al (2012) Garmo et al (2003), Balistrieri et al (2007, Casiot et al (2009), Uribe et al (2011), Roig et al (2011), Panther et al (2014, Shiva et al (2016Shiva et al ( , 2017, Lucas et al (2015), Shiva et al (2015), Wang et al (2016bWang et al ( , 2017b, dos Anjos et al ( 2017), Schoyen et al (2017), Cánovas et al (2020) Table 3 Studies of the diffusive gradients in thin film technique applied in terrestrial systems for the determination of different species of metals and metalloids (published works found in web of knowledge from its development in 1994 up to the present time in 2020)…”

Transport and speciation of uranium in groundwater-surface water systems impacted by legacy milling operations

“…Diffusive gradients in thin-films (DGT) and diffusive equilibrium in thin-films (DET) are methods of measuring fine-scale (cm to mm) solute concentrations in surface waters and sediment pore waters (Davison and Zhang, 2016). They have been used to quantify contaminant concentrations and biogeochemical processes in a variety of environments, including lacustrine (Ma et al, 2020;Zhang et al, 1995), estuarine (Cánovas et al, 2020), marine (Parker et al, 2017), and freshwater sediments (Byrne et al, 2015). Typically, DET devices are used to measure equilibrium surface water and sediment pore water concentrations by allowing solutes to diffuse through a membrane layer (0.45 μm) into an inner hydrogel layer (usually 0.12 cm thick).…”

The Evolution of Pollutant Concentrations in a River Severely Affected by Acid Mine Drainage: Río Tinto (SW Spain)

“…The high concentrations of pollutants transported by both rivers have a severe environmental impact on the estuary, where most of the pollutants precipitate when the acid waters are neutralized by mixing with alkaline seawater. High concentrations of metal(loid)s such as As, Cd, and Pb have been measured in the estuarine waters, sediments, and biota [18][19][20][21]. Nevertheless, some of the most conservative metals under circumneutral pH conditions, such as Zn, Cd, and Mn, reach the Atlantic Ocean or even the Mediterranean Sea [22,23].…”
