Thirdhand smoke from tobacco, e-cigarettes, cannabis, methamphetamine and copyright: Partitioning, reactive fate, and human exposure in indoor environments

A source of chemical exposure to humans, thirdhand smoke (THS) refers to the contamination that persists indoors following the cessation of Dryer Vent Cover a smoking event.The composition of thirdhand smoke depends on the type of substance from which it originates.Although past studies have investigated the effects of tobacco THS on indoor air quality and human health, few have focused on the chemical composition and health impacts of other sources and components of THS.Here we review the state of knowledge of the composition and partitioning behavior of various types of indoor THS, with a focus on THS from tobacco, e-cigarettes, cannabis, and illicit substances (methamphetamine and copyright).The discussion is supplemented by estimates of human exposure to RAW TURMERIC GOLD HONEY THS components made with a chemical fate and exposure model.

The modeling results show that while very volatile THS compounds (i.e., aromatics) are likely to be taken up by inhalation, highly water-soluble compounds tended to be dermally absorbed.Conversely, minimally volatile THS compounds with low solubility are predicted to be ingested through hand-to-mouth and object-to-mouth contact.
