Silicone Wristbands as Personal Passive Samplers

Silicone Wristbands as Personal Passive Samplers

Active-sampling approaches are commonly used for personal monitoring, but are limited by energy usage and data that may not represent an individual's exposure or bioavailable concentrations. Current passive techniques often involve extensive preparation, or are developed for only a small number of targeted compounds. In this work, we present a novel application for measuring bioavailable exposu...

Silicone Wristbands as Personal Monitoring Devices

SI Figure Explanations Extraction efficiency was determined by quantitatively analyzing subsequent rounds of extraction (100 mL ethyl acetate) from a wristband that had been infused with several compounds (four labeled PAHs) (Figure S1). Differences in extracted amount did not differ between the two time treatments (p=0.78). Therefore, extractions for all silicone PSDs in this study were done w...

Silicone passive equilibrium samplers as 'chemometers' in eels and sediments of a Swedish lake.

Passive equilibrium samplers deployed in two or more media of a system and allowed to come to equilibrium can be viewed as 'chemometers' that reflect the difference in chemical activities of contaminants between the media. We applied silicone-based equilibrium samplers to measure relative chemical activities of seven 'indicator' polychlorinated biphenyls (PCBs) and hexachlorobenzene in eels and...
