Research Update <continued> In addition, researchers investigated the ability of normal daily activities, such as walking through the house, vacuuming, or moving furniture, to re-suspend methamphetamine and other chemical contaminants. The results from this study indicate that detectable levels of airborne iodine, hydrochloric acid, and methamphetamine can be found throughout the house for at least 24 hours after the cook. In addition, normal activities, such as walking and vacuuming can re-suspend these contaminants. The study also found that the majority of re-suspended methamphetamine is less than 1 micron in diameter, which allows these particles to penetrate to the deepest part of the lungs where it is rapidly absorbed into the bloodstream. Not only may this pose an exposure problem for innocent bystanders living in the home (such as children), but also for contractors performing remediation of former meth labs. Therefore, it is important that contractors and others who may enter former meth labs wear the appropriate personal protective equipment.
