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
Application of ion mobility spectrometry for the detection of human urine
(2010)The aim of the present study was to evaluate the suitability of ion mobility spectrometry (IMS) for the detection of human urine as an indication of human presence during urban search and rescue operations in collapsed ...

Article
Combined chemical and optical methods for monitoring the early decay stages of surrogate human models
(2011)As the body decays shortly after death, a variety of gases and volatile organic compounds (VOCs) constantly emanate. Ethical and practical reasons limit the use of human corpses in controlled, time-dependent, intervening ...

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
Discriminant Analysis of Volatile Organic Compounds data related to a new location method of entrapped people in collapsed buildings of an earthquake
(2006)Discriminant Analysis is used as a part of a research, which aims at using expired air analysis for the early location of entrapped people under the ruins of collapsed buildings in an earthquake. This work focuses on the ...

Article
Environmental aspects of VOCs evolved in the early stages of human decomposition
(2007)In the present study, the time profile, measured as "accumulation", of volatile organic compounds (VOCs) produced during the early stages of human decomposition was investigated. A human cadaver was placed in a sealed bag ...

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
Physiology and biochemistry of human subjects during entrapment
(2013)A classification of various categories of entrapped people under the ruins of collapsed buildings after earthquakes, technical failures or explosions is proposed. Type and degree of injury at the moment of building collapse ...

Article
Prediction of blood:air and fat:Air partition coefficients of volatile organic compounds for the interpretation of data in breath gas analysis
(2016)In this article, a database of blood:air and fat:air partition coefficients (λ b:a and λ f:a) is reported for estimating 1678 volatile organic compounds recently reported to appear in the volatilome of the healthy human. ...

Article
Preliminary investigation of permeation profiles of selected head-space urine volatiles (2-Heptanone, n-Octanal) using IMS
(2012)The late location of entrapped victims in collapsed buildings is the main reason of high mortality during urban search and rescue (USaR) operations after natural or man-made disasters. Consequently, an effort is currently ...

Article
Preliminary investigation of using volatile organic compounds from human expired air, blood and urine for locating entrapped people in earthquakes
(2005)A preliminary investigation on the possibility of using volatile organic compounds (VOCs) determination of expired air, blood and urine, for the early location of entrapped people in earthquakes, has been carried out. A ...

Article
A scale-up field experiment for the monitoring of a burning process using chemical, audio, and video sensors
(2014)Fires are becoming more violent and frequent resulting in major economic losses and long-lasting effects on communities and ecosystems
-
Article
A study of volatile organic compounds evolved from the decaying human body
(2005)Two men were found dead near the island of Samos, Greece, in the Mediterranean sea. The estimated time of death for both victims was 3-4 weeks. Autopsy revealed no remarkable external injuries or acute poisoning. The exact ...

Article
A study of volatile organic compounds evolved in urban waste disposal bins
(2005)Volatile organic compounds (VOCs) evolved in urban waste disposal bins in different situations were studied. Waste of various loads (full, empty, partially filled bins), remained uncollected in the containers for variable ...

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 ...
