Alpine ecosystems are the main accumulation sites of trace metals from the atmosphere [1-2]. According to studies on alpine-like sediments in the Eastern Tibetan Plateau, anthropogenic metals began to appear around 1950, significantly increased in the 1980s, and peaked in the mid-1990s. Over 80% of Cd, Pb and Zn were quantified from anthropogenic emissions in atmospheric deposition since the mid-1990s atmosphere [3]. In Europe, the Western Carpathians are one of the most lead-polluted alpine regions [4]. Seasonal fluctuations in the lead concentrations in foliar parts of alpine plants and bones of feral pigeons have been recorded, with values higher in winter and early spring months than in summer months [1, 5-6]. In general, the presence of heavy metals in organisms shows the bioavailability of these heavy metals, which accumulate in plant parts and then subsequently are absorbed by animals. Prolonged

“…The authors did point out, however, that in‐field methods would need to be developed to accommodate their findings (Rouillon & Taylor, ). On the other hand, others have suggested that calibration and data processing is still an issue that requires further development (Butler, Cairns, Cook, & Davidson, ).…”

Environmental forensics aims to provide investigations into pollution incidents to establish the source of the pollution and any environmental or human health impacts. Casework is strongly reliant on field investigations and subsequent laboratory‐based analysis for confirmation of pollutants present. Current advances in field‐portable instrumentation are shaping the environmental forensics discipline and provide an evolutionary change in the operational capabilities of environmental investigators. The implementation of field‐portable equipment into the environmental investigative framework provides great advances and opportunities, but also needs to be performed with caution to ensure reliable results. Combining the use of field‐portable instrumentation with small mobile forensic laboratories provides for a rapid and flexible emergency response capability that can also be applied to non‐emergency scenarios to aid pollution mapping and tracking, including source determination. The field‐portable equipment can be used in the controlled environment of the mobile laboratory, but can also be used in‐situ where required. Although field‐portable equipment is not likely to replace laboratory‐based analysis methods in the near future, it does provide important intelligence to the field investigator, resulting in a more targeted and detailed investigation of the scene. This allows for a more focussed laboratory‐based investigation and will result in more rapid and appropriate investigations into environmental incidents. Ultimately, this will ensure a better protection of the environment and human health.

Adsorbent regeneration is critical for a continuous adsorption-regeneration process and often underestimated. In this work, the regeneration of bifunctional Ag X O@SBA-15 for [O]-induced reactive adsorptive desulfurization of liquid fuel is reported and further investigated. The spent Ag X O@SBA-15 was regenerated in various types of solvents followed by calcination and tested in multiple desulfurization-regeneration cycles. The effects of regenerate solvents were also compared systematically. The original and regenerated Ag X O@SBA-15 was characterized by X-ray diffraction, transmission electron microscopy, energy-dispersive X-ray spectroscopy, N 2 adsorption, X-ray photoelectron spectroscopy and atomic absorption spectrometry. The recovery of desulfurization capacity using various solvents follows the order of acetonitrile [ acetone [ ethanol [ methanol [ water. Owing to the complete reduction of silver species to Ag 0 and severe agglomeration of Ag 0 , the bifunctional Ag X O@SBA-15 demonstrating [ 85% (2.60 mg-S/g) of sulfur removal dramatically reduced to \ 46% (1.56 mg-S/g) after only 1st-cycle regeneration. It is suggested that polar organic species strongly adsorbed (or residual) on the spent Ag X O@SBA-15, in that case, after solvent wash may contribute to the accelerated decomposition of Ag ? to Ag 0 in the following calcination step. The desulfurization capacity decreased rather mildly in the later regeneration runs. Cautious choice of regeneration conditions and strategies to rational design stabilized adsorbents is required to avert the adsorbent deactivation.
