Silicone Wristbands as Passive Samplers in Honey Bee Hives

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...

folding-leg hives for honey bee

abstrac:    in recent years, honey bee products other than just honey such as pollen, propolis, waxes and venoms have gained considerable attention. hive is the most important tool in honey bee industry, the proper construction of which could play a key role in improving honey bee production.  since 1382, investigations have been done on hives made inside the country to eliminate deficiencies s...

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...
