Pyrethroid levels in toddlers' breathing zone following a simulated indoor pesticide spray.

ABSTRACT: Application of pyrethroid insecticides in residential settings may result in children's exposures to these chemicals and possible adverse health effects. Household dust is a recognized reservoir for pyrethroids and a potential medium for multi-route pyrethroid exposure. Young children move and play in a manner that resuspends dust, and since their breathing zone is close to the floor, they will have higher inhalation exposure to pesticide-laden dust than other age groups. Directly measuring a toddler's exposure to household dust presents many logistic challenges. We simulated the dust resuspension induced by a toddler using a robot, which also served as a platform to collect air samples at the toddler's breathing zone height. We performed simulated pyrethroid residential spray and dust res
