Congratulations to Josh for publishing the first paper of his doctoral research! The paper titled "Silicone wristbands for assessing personal chemical exposures: Impacts of movement on chemical uptake rates" evaluated factors affecting accumulation rates of organic chemicals onto silicone wristband personal exposure samplers. Josh's study explored how movement affects the ability of silicone wristbands to collect semi-volatile organic compounds (SVOCs) from the air. Wristbands are used as personal devices to measure chemical exposure. Josh and his collaborators found that wristbands collected chemicals much faster when they were in motion compared to when they were stationary. This increase in collection was linked to the chemical properties of the substances and suggests that factors like air flow alone don't fully explain SVOC uptake rates. Other factors, such as particle deposition and skin contact, also influence chemical uptake.
