Hair Biomonitoring

In recent years, methods for measuring nicotine in hair have been developed and validated with the goal of characterizing long-term tobacco exposure. Because human hair grows at roughly 1 cm per month, the cumulative exposure over a given period of time can be quantified by obtaining the appropriate length of hair from the scalp. Hair nicotine is a good measure of cumulative exposure to secondhand smoke over a period of several months. While hair samples are relatively easy to collect, sample analysis requires access to a sophisticated analytical laboratory.
