Current and future CBRN terrorist threats

Current and future CBRN terrorist threats

The latter, although responsible for very significant physical and psychological injuries, have devastating social and economic disruption consequences that are not comparable in intensity to those of…

Forest fires: is the fire brigade hood effective in filtering smoke and fine particles?

In our blog dated August 30, 2016, we already looked at firefighters’ health and in particular the long-term impact of toxic substances such as polycyclic aromatics (PAHs), PCBs, bisphenol A, benzenes and heavy oils, VOCs and other oxygenated compounds causing cancers of the rectum, anus, prostate and liver, melanoma, multiple myeloma and other acute myeloid…

Mustard gas causes epigenetic changes: new notions in the CBRN domain

Mustard gas causes epigenetic changes: new notions in the CBRN domain

Recent scientific publications show that mustard gas and organophosphates can cause epigenetic changes: we found it interesting to study this problem in order to better understand it and the consequences in terms of pathogenicity. These phenomena are especially important because they also seem to be implicated in the “Gulf War Syndrome”, which is not yet…

Novichok nerve agents. A BCRNe threat

Novichok nerve agents. A BCRNe threat

Among the chemical weapons in the field of NRBCE, we generally distinguish vesicants (mustard, lewisite), hemotoxics (hydrocyanic acid, cyanogen chloride) and organophosphorus neurotoxics (Tabun, Sarin, Soman). To the latter are added the VX and VR versions more toxic than previous. On the other hand, little is known about novichoks, whose toxicity is still greater than that…

From BCN  to BCRNE

From BCN to BCRNE

Called the BCN threat – Bacteriological or Biological, Chemical, Nuclear, – during the Cold War, we now call it the BCRNE threat –  Biological, Chemical, Radiological, Nuclear, Explosive. Beyond the change of acronym, it is also a paradigm shift that has been achieved: the state threats “mass destruction weapons” have been replaced by the terrorist threats…
