“…It is paradigmatic that a very recent publication proposing an analytical eco-scale for assessing the greenness of analytical procedures [74] considers energy consumption per analysis based only on three values taken from a communication to a conference. Astonishingly, the same reference is the only one given in a recent chapter on "energy savings in analytical chemistry" [75]. In fact, it is somewhat surprising that methods that involve the use of sophisticated apparatus, such as an ICP-MS, can be considered "green".…”

Abstract:The practical and conceptual challenges faced by the analysis of trace elements present in natural waters are not merely, as is often thought, an endless race towards lower detection limits or to the development of techniques allowing the determination of any possible chemical species formed by all chemical elements. Rather, as discussed in this paper, they include the development of (i) robust, cheap, and reliable methods that could also be used by laypeople (the experience gained in the development of field kits for As is discussed as an example from which similar developments for other elements may be drawn); (ii) more environmentally-friendly methods (the current guiding criteria probably being too simplistic); and (iii) methods making it possible to follow diel concentration changes and sharp concentration variations caused by the probable increase of heavy rainfall events. This paper also claims that neither the measurement of total concentrations (reliable methods are lacking for many elements of the periodic table of trace elements, as illustrated through the cases of Bi, Te, and Sb), nor chemical speciation analysis, are as mature as often thought. In particular, chemical speciation studies demand the development of a better, comprehensive conceptual framework. A trial is carried out to lay the basis of such a framework.

“…It also has usage in bioactive compounds extraction and separation from living organisms, tissues or cells; which are widely known for providing beneficial effects on human health [44][45][46]. For example, headspace DES microextraction prepared by mixing choline chloride with ethylene glycol at different ratios extracted terpenoids from Chamaecyparis obtusa leaves [47]. The terpenoids swiftly extracted by this method showed various anti-disease properties like antimicrobial, antitumor and antimalarial activities.…”

: Green separation science involves extraction, pre-concentration and chromatographic analysis aiming at minimizing environmental impact by reducing energy and reagent usage and reducing or eliminating waste generation. However, the enrichment of trace analytes and/or the analysis of complex matrices most frequently require several steps before analysis, such as extraction, pre-concentration, clean up and preparative chromatography. Thus, alternative and greener separation techniques and solvents are replacing classical methods to diminish the carbon footprint and increase sustainability. Moreover, many innovations are also emerging to curtail the environmental impact of samples analysis; such as micro or nano analytical platforms, sensor-based systems and direct injection to high resolution mass spectrometry. The current review provides an updated account of the green and sustainable separation science techniques. The current innovations on greener separations and their application in different fields of study are discussed.

The aim of this project was to develop a general concept to assess the laboratory experiments in the instrumental analysis laboratory, at the Institute of Chemistry and Biological Chemistry (ICBC) at the Zurich University of Applied Sciences (ZHAW), in terms of their sustainability and, where possible, to improve the sustainability rating of the laboratory experiments. Hence, the primary objective was to implement an empirical assessment methodology, including the "Sustainability Code" that was composed of four parts and a "Sustainability Load Index". During the spring semester 2015, 105 different experimental projects were performed in the ICBC's analytical chemistry practical course. These were carried out on 18 different instrumental workspaces, encompassing 12 different analytical methodologies. For the development of the first and second parts of the Sustainability Code, information concerning the chemical substances (in any state-solid, liquid or gas) used and the energy consumption of the apparatus was recorded. The third and fourth parts contain (approximate) information on the use of consumables and the sustainability of the method with reference to the apparatus used. The Load Index (LI) consists of an aggregation (summary) of the direct causality indicators 'substances' and 'energy' into a single figure. The experiments were classified on a 3-level Load Index Scale into 'ideal' analysis methods (LI> 20), 'sustainable' methods of analysis (LI 20-200), and analysis methods 'with potential for optimization' (LI <200). The assessment criteria described here, specifically designed for an analytical process in a university environment, may also serve as a useful guide for semi-quantitative assessment of both familiar and new methods in analytical chemistry practical courses and in laboratory practice. It may also be useful in general research laboratory environments.
