wristband (IMAGE) Texas A&M University Caption Participants in the study carried backpacks containing air-sampling equipment and a silicone wristband attached to it to analyze exposure to polycyclic aromatic hydrocarbons (PAHs). The research team found that the silicone wristbands, when used as passive samplers, have the ability to bind smaller molecular weight semi-volatile PAHs in a similar pattern as active sampling.
