“…In the reviewed literature, natural and synthetic estrogens were detected always at ng/L levels in Portuguese surface waters, similar or above those concentrations reported in European countries. While phytoestrogens were reported as frequently detected at μg/L range, the authors pointed out that most publications about pharmaceuticals in Portuguese surface waters published before 2016 referred only few therapeutic classes in the north of Portugal and most consisted in the application of new analytical methods rather than consistent monitoring data (Ribeiro et al 2016b;Balaram et al 2022a). The reports on a broad range of classes of pesticides including priority substances of European Directive 39/2013/EU were collected in that review from 2001 to 2015, some of them up to μg/L, including atrazine that was already banned in Europe.…”

Water contamination by emerging contaminants is increasing in the context of rising urbanization, industrialization, and agriculture production. Emerging contaminants refers to contaminants for which there is currently no regulation requiring monitoring or public reporting of their presence in our water supply or wastewaters. There are many emerging contaminants such as pesticides, pharmaceuticals, drugs, cosmetics, personal care products, surfactants, cleaning products, industrial for-mulations and chemicals, food additives, food packaging, metalloids, rare earth elements, nanomaterials, microplastics, and pathogens. The main sources of emerging contaminants are domestic discharges, hospital effluents, industrial wastewaters, runoff from agriculture, livestock and aquaculture, and landfill leachates. In particular, effluents from municipal wastewater treatment plants are major contributors to the presence of emerging contaminants in waters. Although many chemicals have been recently regulated as priority hazardous substances, conventional plants for wastewater and drinking water treat-ment were not designed to remove most emerging contaminants. Here, we review key examples of contamination in China, Portugal, Mexico, Colombia, and Brazil. Examples include persistent organic pollutants such as polychlorinated biphenyls, dibenzofurans, and polybrominated diphenyl ethers, in lake and ocean ecosystems in China; emerging contaminants such as alkylphenols, natural and synthetic estrogens, antibiotics, and antidepressants in Portuguese rivers; and pharmaceuticals, hormones, cosmetics, personal care products, and pesticides in Mexican, Brazilian, and Colombian waters. All continents are affected by these contaminants. Wastewater treatment plants should therefore be upgraded, e.g., by addition of tertiary treatment systems, to limit environmental pollution.

“…2,3 Since then, MC-ICP-MS has undergone rapid evolution and become more versatile in generating high-precision isotopic information. 4 The precision achieved was about ±1‰ (2SD) 2,3,5 when this technique was first applied on Li isotopic analysis. In recent studies, the precision for the mono-element Li standard solution IRMM-016 has been improved to within the range of ±0.09 to ±0.52‰, most of which are between ±0.24‰ and ±0.35‰, and the representative literature includes Hu and Teng (Nu Plasma II, ±0.19‰), 6 Huang et al (Neptune, ±0.12‰ over 6 months), 7 Li et al (Plasma 3, ±0.18‰ over 2 years), 8 Lin et al (Neptune Plus, ±0.24‰ over a year), 9 Millot et al (Neptune, ±0.24‰ over 10 months), 10 Liu et al (Neptune Plus, ±0.33‰), 11 Kuessner et al (Neptune, ±0.34‰ of LSVEC (an acronym of Li carbonate) over a year), 12 Machpherson et al (Neptune Plus, ±0.35‰ over 5 months) 13 and Zhu et al (Neptune Plus, ±0.52‰ of LSVEC over a year).…”

“…For example, XAFS cannot distinguish metals that bind to surface >Al-OH or >Si-OH functional groups owing to the weak and similar X-ray backscattering power between Al (atomic number of 13) and Si (atomic number of 14). Recently, advances in multicollector inductively coupled plasma–mass spectrometry (MC-ICPMS) have proven the application of metal stable isotopes to study metal adsorption phenomena to be a powerful new approach. − Different sorption mechanisms could be associated with significant isotope effects, yielding distinct magnitudes of metal isotope fractionation. − For example, forming inner-sphere surface complexes on the surface of amorphous silicon oxide led to extremely large Zn isotopic fractionations (up to 0.94‰), while outer-sphere complexes and Zn–Al LDH exhibited little to no isotopic fractionation (∼0.0‰). , Furthermore, it was revealed that Zn stable isotopic fractionation is sensitive to local bonding structures. The tetrahedral Zn inner-sphere surface complex formed on the ferrihydrite surface yields an isotopic fractionation of ∼0.53‰, which is significantly larger than the ∼0.29‰ fractionation caused by surface complexation of Zn by goethite, which is an octahedrally coordinated environment determined from XAFS .…”

While silicate has been known to affect metal sorption on mineral surfaces, the mechanisms remain poorly understood. We investigated the effects of silicate on Zn sorption onto Al oxide at pH 7.5 and elucidated the mechanisms using a combination of X-ray absorption fine structure (XAFS) spectroscopy, Zn stable isotope analysis, and scanning transmission electron microscopy (STEM). XAFS analysis revealed that Zn−Al layered double hydroxide (LDH) precipitates were formed in the absence of silicate or at low Si concentrations (≤0.4 mM), whereas the formation of Zn−Al LDH was inhibited at high silicate concentrations (≥0.64 mM) due to surface-induced Si oligomerization. Significant Zn isotope fractionation (Δ 66 Zn sorbed-aqueous = 0.63 ± 0.03‰) was determined at silicate concentrations ≥0.64 mM, larger than that induced by sorption of Zn on Al oxide (0.47 ± 0.03‰) but closer to that caused by Zn bonding to the surface of Si oxides (0.60−0.94‰), suggesting a presence of Zn−Si bonding environment. STEM showed that the sorbed silicates had a close spatial coupling with γ-Al 2 O 3 , indicating that >Si−Zn inner-sphere complexes (">" denotes surface) likely bond to the γ-Al 2 O 3 surface to form >Al−Si−Zn ternary inner-sphere complexes. This study not only demonstrates that dissolved silicate in the natural environment plays an important role in the fate and bioavailability of Zn but also highlights the potential of coupled spectroscopic and isotopic methods in probing complex environmental processes.
