Repellents military personnel

As discussed in Section 18.6, military personnel were administered PB and also exposed to DEET (an insect repellant) and permethrin (an insecticide), the combination of which produced unanticipated neurological symptoms. 621 When the exposures from diesel exhaust, oil well fire smoke, and spent munitions combustion products are added to these, the onset of other unexpected health effects are not surprising. It is to be noted that the chemical mixtures to which the military personnel were exposed to included large numbers of lipophilic and hydrophilic species.
