Maternal exposure to polycyclic aromatic hydrocarbons in South Texas, evaluation of 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...

Evaluation of Car Air Filters’ Efficiency as Active Samplers for Polycyclic Aromatic Hydrocarbons and Heavy Metals

In this study, an innovative and inexpensive approach, based on car engine air filters (CAFs), was used to monitor polycyclic aromatic hydrocarbons (PAHs) and heavy metals (HMs). CAFs were collected from two taxi garages in Guangzhou and analyzed for PAHs and heavy metals. The total concentrations of eight high molecular weight PAHs (ΣPAHs) ranged from 923 to 11378 μg/CAF. The average ΣPAHs con...

personal exposure to polycyclic aromatic hydrocarbons in newsagents in tehran, iran.

vehicle exhaust is a major source of exposure to polycyclic aromatic hydrocarbons (pahs) found in the urban atmosphere. newsagents usually work close to heavy traffic flow. the purpose of this study was to assess the breathing zone exposure of newsagents to pahs found in the urban atmosphere of tehran city during summer and autumn seasons and comparing the levels of exposure in both seasons.fif...
