Dear customer,
Thanks for your question.
Basically very few studies have been done to measure the tobacco smoke exposure in passive smoking. Of the biomarkers available cotinine has now become the biomarker of choice. Cotinine has been measured in blood, saliva, and urine. However for measurement of long-term, cumulative exposure to tobacco smoke hair analysis is more reliable.
The dangerous particles in passive secondhand smoke can linger in the air for hours or even longer. Also of concern is the residue that clings to a smoker's (both active and passive) hair and clothing, as well as cushions, carpeting and other goods — and this is sometimes referred to as thirdhand smoke. This thirdhand smoke can also pose risks, especially for children.
Take care.
