![عکس صفحه اول مقاله: Showering effectiveness for human hair decontamination of the nerve agent VX Showering effectiveness for human hair decontamination of the nerve agent VX](/preview/png/2580200.png)
• An in vitro model was designed to evaluate hair showering decontamination effectiveness.
• The nerve agent VX persistently contaminated human hair.
• Partial hair decontamination of VX was achieved following 1-min showering.
• Using Fuller’s Earth or RSDL prior to showering enhanced hair decontamination.
• Hair decontamination is an important part of the entire decontamination process.
In this work, our goals were to establish whether hair decontamination by showering one hour post-exposure to the highly toxic organophosphate nerve agent VX was effective, whether it required the addition of a detergent to water and, if it could be improved by using the adsorbent Fuller’s Earth (FE) or the Reactive Skin Decontamination Lotion (RSDL) 30 min prior to showering. Hair exposure to VX and decontamination was performed by using an in vitro model. Hair showering led to 72% reduction of contamination. Addition of detergent to water slightly increased the decontamination effectiveness. Hair treatment with FE or RSDL improved the decontamination rate. Combination of FE use and showering, which yielded a decontamination factor of 41, was demonstrated to be the most effective hair decontamination procedure. Hair wiping after showering was shown to contribute to hair decontamination. Altogether, our results highlighted the importance of considering hair decontamination as an important part of body surface decontamination protocols.
