“…LG partitions exclusively to a submicrometer liquid or solid aerosol phase (Kleeman et al, 2008), and is stable in the atmosphere during long-range transport (Fraser et al, 2000). Thus, once formed as a pyrolysis product of biomass combustion, it is used as an organic marker in atmospheric modeling studies (Fraser et al, 2000;Simoneit et al, 1999aSimoneit et al, , b, 2001Elias et al, 2001), in sediment and Antarctic ice cores for understanding the paleorecord (Gambaro et al, 2008), in liquid biofuel synthesis (Branca et al, 2003;Gravitis et al, 2004), and as a urinary biomarker for approximating animal and human exposures to biomass smoke (Migliaccio et al, 2009). For these reasons, there is high demand for quantitative analytical data for LG.…”

A fast two-dimensional gas chromatography (GC-MS) method that uses heart-cutting and thermal extraction (TE) and requires no chemical derivatization was developed for the determination of anhydro-sugars in fine aerosols. Evaluation of the TE-GC-GC-MS method shows high average relative accuracy (≥90%), reproducibility (≤10% relative standard deviation), detection limits of less than 3 ng/μL, and negligible carryover for levoglucosan, mannosan, and galactosan markers. TE-GC-GC-MS- and solvent extraction (SE)-GC-MS-measured levoglucosan concentrations correlate across several diverse types of biomass burning aerosols. Because the SE-GC-MS measurements were taken 8 years prior to the TE-GC-GC-MS ones, the stability of levoglucosan is established for quartz filter-collected biomass burning aerosol samples stored at ultra-low temperature (−50 °C). Levoglucosan concentrations (w/w) in aerosols collected following atmospheric dilution near open fires of varying intensity are similar to those in biomass burning aerosols produced in a laboratory enclosure. An average levoglucosan-mannosan-galactosan ratio of 15:2:1 is observed for these two aerosol sets. TE-GC-GC-MS analysis of atmospheric aerosols from the US and Africa produced levoglucosan concentrations (0.01–1.6 μg/m<sup>3</sup>) well within those reported for aerosols collected globally and examined using different analytical techniques (0.004–7.6 μg/m<sup>3</sup>). Further comparisons among techniques suggest that fast TE-GC-GC-MS is among the most sensitive, accurate, and precise methods for compound-specific quantification of anhydro-sugars. In addition, an approximately twofold increase in anhydro-sugar determination may be realized when combining TE with fast chromatography

“…The concept of zero waste/emission is to maximise recycling, minimise waste/emission, reduce consumption and ensure that products are planned to be recovered internally or externally (Glavič and Lukman, 2007). The ultimate goal is to produce no waste in air, water and land (Gravitis et al, 2004). In contrast to C2C, the approach is rather reactive in that it seeks to reduce the unintended negative consequences of processes of production and consumption (Braungart et al, 2007).…”

This paper investigates environmental sustainability dynamics of an industrial system through a case study on the UK medical technology sector. This paper builds on an industrial system framework involving institutions, specialist firms, value/supply chains and industrial actors. Environmental sustainability dynamics are explored through infrastructure and structure factors of industrial systems that are primarily developed from theoretical domains of manufacturing systems, production networks and supply chains. Research findings suggest that structural components influence the industry system more radically than the infrastructural components. Environmental sustainability dynamics depend on the size of industrial actors, types/characteristics of product and process, and availability of specialist (funding/technology) firms.Keywords: sustainability in operations and logistics; healthcare operations management; supply network design; UK.Reference to this paper should be made as follows: Kumar, M., Harrington, T.S., Srai, J.S. and Minakata, Y.
