“…Pena‐Mendez et al . developed micro‐extraction and laser desorption ionisation (LDI) of SOM and of humic acids directly from soils; the method permitted the fast screening of SOM to obtain fingerprints and differences between soils from various environments. The procedure was applied to soil samples from several continents, including Antarctica.…”

A focus on the studies of the Antarctic environment that have been performed by mass spectrometry is presented herein; our aim is to give evidence of the essential role of this instrumental technique in the framework of the scientific research in Antarctica, with a comprehensive review on the main literature of the last two decades. Due to the wideness of the topic, the present review is limited to the determination of organic pollutants, natural molecules and biomarkers in Antarctica, thus excluding elemental analysis and studies on inorganic species. The work has been divided into five sections, on the basis of the considered environmental compartment: air; ice and snow; seawater, pack ice and lakes; soil and sediments; and organisms and biomarkers.

“…To investigate the above-mentioned affinity of Hg for organic carbon, a method is also needed to determine the carbon content of house dust. The most commonly used methods for the determination of TC in environmental samples are: Time-of-flight mass spectrometry techniques, dry combustion by automated system, wet chemical oxidation, and loss-on ignition [23][24][25]. In these methods, the total carbon (TC) content of a sample corresponds to the sum of total organic carbon (TOC) and total inorganic carbon (TIC) [23].…”

Mercury (Hg) is one of the top ten chemicals of concern for public health, according to the World Health Organization. This study investigates Hg concentrations in house dust collected from urban single family homes, to better understand typical indoor residential exposures. Using direct solid sample analysis, total Hg and carbon (TC) were determined in the <80 µm fraction of settled dust samples collected under the Canadian House Dust Study. Hg concentrations displayed a log-normal distribution with median/geomean of 0.68/0.70 mg/kg (n = 995). A small subset (<1%) of homes exhibited anomalously high dust Hg concentrations (>9.0 mg/kg). A comparison of Hg concentrations in fresh dust and household vacuum dust collected from the same homes indicated no significant difference in the two sampling methods. Total carbon concentrations displayed a median/geomean of 29.3/28.5% (n = 1011). A significant correlation between total Hg and TC in house dust (p < 0.00001) reflects the association between Hg and organic carbon previously observed in soil and sediments. The results of this study indicate a 10-fold enrichment in house dust compared with the average background concentrations reported for soil and sediments (0.07 mg/kg). The observed enrichment is attributable to Hg emissions from indoor sources and/or Hg carried home from occupational sources.
