Analysis of volatile organic compounds released from the decay of surrogate human models simulating victims of collapsed buildings by thermal desorption-comprehensive two-dimensional gas chromatography-time of flight mass spectrometry
(2015)Field experiments were devised to mimic the entrapment conditions under the rubble of collapsed buildings aiming to investigate the evolution of volatile organic compounds (VOCs) during the early dead body decomposition ...

Article
A compendium of volatile organic compounds (VOCs) released by human cell lines
(2016)Volatile organic compounds (VOCs) offer unique insights into ongoing biochemical processes in healthy and diseased humans. Yet, their diagnostic use is hampered by the limited understanding of their biochemical or cellular ...

Article
Near real-time VOCs analysis using an aspiration ion mobility spectrometer
(2013)The ChemPro 100i chemical detector (aspiration-type ion mobility spectrometer) was used for the detection of selected volatile organic compounds known to be potential indicators of human presence. The targeted group of ...

Article
Permeation profiles of potential urine-borne biomarkers of human presence over brick and concrete
(2012)Headspace solid phase micro-extraction gas chromatography-mass spectrometry (SPME-GC-MS) analysis was performed over an in-house made filling chamber loaded with brick or concrete, mimicking a potential entrapment scene ...

Article
Spatial characteristics of urinary BTEX concentrations in the general population
(2017)Benzene, toluene, ethylbenzene, o-, m-, and p-xylenes (BTEX) are ubiquitous outdoor and indoor air pollutants associated with both environmental and health effects. The objective of this exploratory study was to determine ...

Article
Temporal profiling of human urine VOCs and its potential role under the ruins of collapsed buildings
(2012)Context: The scent profile of human urine was investigated as potential source of chemical markers of human presence in collapsed buildings after natural or man-made disasters. Objective: The main goals of this study were ...

Article
Trace detection of endogenous human volatile organic compounds for search, rescue and emergency applications
(2015)Since Pauling's paper in the 1970s, interest has increased in volatile organic compounds (VOCs) released from different bio-fluids, such as blood and urine. A number of VOCs reflect internal biochemical pathways occurring ...

Article
The trapped human experiment
(2011)This experiment observed the evolution of metabolite plumes from a human trapped in a simulation of a collapsed building. Ten participants took it in turns over five days to lie in a simulation of a collapsed building and ...

Volatile emissions during storing of green food waste under different aeration conditions
(2016)Controlled field experiments were carried out for monitoring the emissions of three plastic commercial household waste bins, which were adapted for studying the effect of aeration process in the evolved volatiles, during ...
