“…More recently, X-ray absorption near edge structure (XANES) and extended X-ray absorption fine-structure (EXAFS) assay, followed by liner combination fitting (LCF), were used to study the transformation of metals in complex environmental/biological matrix in a quantitative way (Fulda et al, 2013a(Fulda et al, , 2013b. These methods might also be suitable for the quantification of NPs dissolution in complex matrix without pre-separating the ions and particles.…”

These techniques can also be used to study the dissolution of NMs at the nano-bio interface without the pre-separation of ions and particles [39,41].

With the rapid development of nanoscience and nanotechnology, more engineered nanomaterials (NMs) are being released into the environment. Such releases might lead to unwanted exposure. The dissolution of NMs at nano-bio interfaces is one of the most noteworthy causes of the toxicity of dissolvable NMs. A growing number of studies are focusing assessing NMs dissolution during exposure tests. This mini-review considers recent developments in the quantitative tools for the assessment of NMs dissolution, and highlights the critical points in the evaluation of the toxicity of dissolvable NMs. nanomaterials, nano-bio interface, dissolution, ions, toxicology

“…The release of Cu from the secondary phases can be enhanced in the presence of organic matter and clay fraction when slags are deposited in soils (Lanteigne et al 2012). On the other hand, if the release is slow and the amount released low, the dissolved load of Cu 2+ will be reduced by common rock-forming minerals such as biotite (Ilton and Veblen 1988) or by the organic matter in soils (Fulda et al 2013) to metallic copper. This path is also well documented by a pH-pε phase diagram (Fig.…”

Historical slags from the past Fe and Cu-Co production were investigated in order to evaluate either their potential for utilization or their long-term environmental risk for unsupervised old smelting areas. Here, we studied ferrous slags produced during the recovery of Fe from siderite-Cu ores in Slovakia and two different types of non-ferrous slags produced during the recovery of Cu and Co from Kupferschiefer ores in Germany. The glassy character, rare occurrence of primary silicate phases, and the lack of secondary phases in Cu slags indicate their stability for a prolonged period of time. Electron microprobe analytical work showed that the metals and metalloids (Cu, Co, Fe, Zn, Pb, As) are largely encased in droplets of matte and metal alloys and remain protected by the glassy matrix with its low weathering rate. Fe and Co slags are composed of high-temperature silicates such as wollastonite, cristobalite, as well as olivine, feldspar, quartz, leucite, pyroxene, and pyroxenoids. The presence of secondary phases attests to a certain degree metal release owing to weathering. Assuming minimal contents of metals in slags after a treatment with dilute H2SO4, slags could be used as pozzolanas for addition to cement.
