“…Taking samples onsite, e.g., in a clandestine laboratory or at a postblast site and transportation to a well-equipped laboratory therefore is usually avoided. Destruction onsite is preferred, even if it involves collateral damage . The relatively high vapor pressure of TATP 1 (6.95 Pa at 25 °C) , combined with the high sensitivity of our test now allows safe and simple noncontact detection of TATP 1 via the gas phase (Figure ).…”

Homemade explosives, such as peroxides, nitrates, and chlorates, are increasingly abused by terrorists, criminals, and amateur chemists. The starting materials are easily accessible and instructions on how to make the explosives are described on the Internet. Safety considerations raise the need to detect these substances quickly and in low concentrations using simple methods. Conventional methods for the detection of these substances require sophisticated, electrically operated, analytical equipment. The simpler chemical detection methods are multistep and require several chemicals. We have developed a simple, onestep method that works similarly to a pH test strip in terms of handling. The analytical reaction is based on an acid-catalyzed oxidation of an electron-rich porphyrin to an unusually stable radical cation and dication. The detection limit for the peroxide-based explosive triacetone triperoxide (TATP), which is very frequently used by terrorists, is 40 ng and thus low enough to detect the substance without direct contact via the gas phase. It is sufficient to bring the stick close to the substance to observe a color change from red to green. Nitrates and chlorates, such as ammonium nitrate, urea nitrate, or potassium chlorate, are detected by direct contact with a sensitivity of 85−350 ng. A color change from red to dark brown is observed. The test thus detects all homemade explosives and distinguishes between the extremely impact-, shock-, and friction-sensitive peroxides and the less sensitive nitrates and chlorates by color change of a simple test strip.

“…As metodologias e até vídeos de preparo e detonação podem ser facilmente obtidas em websites na rede mundial de computadores (FREYE, KINMAN, et al, 2020). No geral, os HME são compostos por misturas binárias entre um oxidante e um combustível, substâncias orgânicas contendo grupos nitro (R-NO2) ou peróxido (R-O-O-R') (DEGREEFF, KATILIE, et al, 2018;REID, RICHES, et al, 2018;NASEM, 2018;LEASE, KAY, et al, 2019).…”

O emprego de explosivos caseiros em ações terroristas tem ganhado destaque em diversos países, ocasionando mortes, feridos, destruição e pânico. Esses materiais são de fácil fabricação e podem ser sintetizados a partir de produtos químicos de uso cotidiano. Nesse contexto, este estudo tem como objetivo apresentar uma revisão bibliográfica dos principais explosivos caseiros mundialmente incidentes, descrevendo suas características, síntese e substâncias precursoras. Os resultados evidenciam a necessidade de atualização da legislação brasileira de controle de produtos químicos, seguindo uma tendência mundial de restringir o acesso aos precursores de explosivos.
