Natural gas extraction, often referred to as “fracking,” has increased rapidly in the U.S. in recent years. To address potential health impacts, passive air samplers were deployed in a rural community heavily affected by the natural gas boom. Samplers were analyzed for 62 polycyclic aromatic hydrocarbons (PAHs). Results were grouped...

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...

The current work sought to develop predictive
models between time-weighted average polycyclic aromatic
hydrocarbon (PAH) concentrations in the freely dissolved
phase and those present in resident aquatic organisms. We
deployed semipermeable membrane passive sampling devices
(SPMDs) and collected resident crayfish (Pacifastacus
leniusculus) at nine locations within and outside of the...

Bioaccessibility in vitro tests measure the solubility of materials in surrogate biofluids. However, the lack
of uniform methods and the effects of variable test parameters on material solubility limit interpretation.
One aim of this study was to measure and compare bioaccessibility of selected economically important
alloys and metals in surrogate...

Contamination of resident aquatic organisms is a major concern for environmental risk assessors. However, collecting organisms to estimate risk is often prohibitively time and resource-intensive. Passive sampling accurately estimates resident organism contamination, and it saves time and resources. This study used low density polyethylene (LDPE) passive water samplers to predict...
