It turns out that your colorful plastic wristband may do more than remind you to “Live strong” or “Keep the faith.” It may also tell you what toxins you’re being exposed to in your daily life.
A new field, “exposomics,” has begun to study the amount of environmental contaminants we are exposed to over our lifetimes, and their impact on genomes and human health.
Silicone can absorb a wide range of compounds, which makes it extremely useful as a passive sampling device. In a recent experiment conducted by Oregon State University, participants were given clean silicone wristbands to wear continuously for a period of 30 days.
The bands were then given to a laboratory for analysis, where they were screened for 1,182 chemicals. Researchers were able to identify 49 different environmental contaminants that participants had been exposed to in varying amounts, including polychlorinated biphenyls (PCBs), pesticides and flame retardants. The most common were diethyl phthalate and tonalide, which are used in personal care products, such as cosmetics and fragrances.
Researchers used an Agilent GC-mass spec system equipped with an Agilent J&W DB-5ms capillary column for their analysis.
