“…Figure 3 shows a conceptual model of the environmental fate and transport processes that Poly. (2, impact the movement of landmine chemical constituents to the land surface for chemical detection. Chemical vapours emanate from buried landmines by permeation through plastic case materials or leakage through seals and seams, and also from surface contamination of the mine case.…”

Large quantity of explosive is manufactured worldwide for use in various types of ammunition, arms, and mines, and used in armed conflicts. During manufacturing and usage of the explosive equipment, some of the explosive residues are released into the environment in the form of contaminated effluents, unburnt explosives fumes and vapours. Limited but uncontrolled continuous release of trace vapours also takes place when explosive-laden landmines are deployed in the field. One of the major technological challenges in post-war scenario worldwide is the detection of landmines using these trace vapour signatures and neutralising them safely. Different types of explosives are utilised as the main charge in antipersonnel and antitank landmines. In this paper, an effort has been made to review the techniques so far available based on explosive vapour detection especially to detect the landmines. A comprehensive compilation of relevant information on the techniques is presented, and their maturity levels, shortcomings, and difficulties faced are highlighted.

“…Deployment of antipersonnel (AP) and antitank (AT) landmines during wartime is another big menaces. Apart from locating these materials, explosive vapour detection is one of the useful and important techniques for: (a) forensic investigations such as arson 2 , (b) postblast residue determinations 3 , (c) mapping mine…”

“…[1][2][3][4][5][6][7][8][9][10] Chemical sensors for the rapid detection of explosive materials have important potential applications, such as tactical and humanitarian demining, remediation of explosives manufacturing sites, [11] and forensic and criminal investigations. [12] Amongst various known chemical explosives, nitroaromatics are the common components in various explosives and make them as common focus in explosive detection. [13][14][15][16] Besides their explosive nature, these nitroaromatics have several health and safety concerns.…”

The application of polymeric films as alarms for explosive materials is a critical issue these days as mandated by homeland security requirements. Amongst the multiple advantageous points of applying polymer films in this area is the fact that they are cheap material, so they can be applied on a broad scale for low cost. The basic idea of the current work is based on the fact that common explosives are electron deficient because of the existence of the nitro-groups in their chemical structures, and this causes their high affinities towards electron rich materials to form charge-transfer complex. Our endeavor is to trace any charge-transfer complex formation, which would definitely cause a recognizable change in their physical properties. These changes in the polymers' physical properties could be utilized as alerts for the existence of explosive materials, especially if such changes could be incorporated into sophisticated electronic circuits that would give strong for traces of explosives.

“…4 Consequently a great number of analytical methods have been developed for monitoring these compounds, for example, mass spectrometry, 5 ion mobility spectrometry, 6 fluorescence, 7 chemiluminescence, 8 surface enhanced Raman spectroscopy, 9 nuclear quadrupole resonance, 10 energy-dispersive X-ray diffraction, 11 neutron activation analysis, electron capture detection, 2 and cyclic voltammetry. 12 These techniques are highly selective, but some are expensive and others are not easily fielded in a small, low-power package.…”

Nanocrystalline porous silicon (PSi) surfaces have been used to detect nitroaromatic compounds in vapor phase. The mode of photoluminescence (PL) is emphasized as a sensing attitude or detection technique. Quenching of PL from nanocrystalline porous surfaces as a transduction mode is measured upon the exposure of nitroaromatic compounds. To verify the detection of explosives, the surface of PSi is functionalized with different groups. The quenching mechanism of PL is attributed to the electron transfer behaviors of quantum-sized nano-crystallites in the PSi matrix to the analytes (nitroaromatics). An attempt has been done to prove that the surface-derivatized photoluminescent PSi surfaces can act as versatile substrates for sensing behaviors due to having a large surface area and highly sensitive transduction mode.
