Thirdhand Cigarette Smoke: Factors Affecting Exposure and Remediation
Thirdhand smoke (THS) refers to components of secondhand smoke that stick to indoor surfaces and persist in the environment. Little is known about exposure levels and possible remediation measures to reduce potential exposure in contaminated areas. This study deals with the effect of aging on THS components and evaluates possible exposure levels and remediation measures. We investigated the con...
متن کاملThirdhand smoke: here to stay.
The first time I had any inkling that nicotine might linger in a room was when I listened to a group of nicotine chemists complaining about how hard it is to keep nicotine out of their laboratories. Their gas chromatography and mass spectroscopy machines are expensive, complex and very sensitive. In order to detect nicotine and cotinine in samples from non-smokers exposed to secondhand smoke, t...
متن کاملThirdhand smoke: a new dimension to the effects of cigarette smoke on the developing lung.
The underlying mechanisms and effector molecules involved in mediating in utero smoke exposure-induced effects on the developing lung are only beginning to be understood. However, the effects of a newly discovered category of smoke, i.e., thirdhand smoke (THS), on the developing lung are completely unknown. We hypothesized that, in addition to nicotine, other components of THS would also affect...
متن کاملOzone, but not nitrogen dioxide, exposure decreases glutathione peroxidases in epithelial lining fluid of human lung.
Antioxidants, such as glutathione peroxidases (GPxs), in epithelial lining fluid (ELF) protect against health effects of oxidant pollutants, which includes O(3) or NO(2). We hypothesized that GPxs concentration in ELF is responsive to O(3) or NO(2) exposure. Subjects underwent two 4-h exposures to O(3) (0.22 ppm) and one to air. In another experiment, subjects underwent 3-h exposures to air and...
متن کاملEarly exposure to thirdhand cigarette smoke affects body mass and the development of immunity in mice
Thirdhand smoke (THS) is the fraction of cigarette smoke that persists in indoor environments after smoking. We investigated the effects of neonatal and adult THS exposure on bodyweight and blood cell populations in C57BL/6 J mice. At the end of neonatal exposure, THS-treated male and female mice had significantly lower bodyweight than their respective control mice. However, five weeks after ne...
