Volatile losses of hydrophobic organic contaminants from a confined disposal facility (CDF) containing dredged contaminated sediments is substantial concern to surrounding communities. A partitioning passive sampling approach using polyoxymethylene (POM) was applied measure long-term average (weeks months) air concentrations resulting evaporation at CDF. Measurements 10 locations the CDF POM sa...
<p>The PIM-passive sampler is a passive using PIM as diffusion layer. This research aimed to optimize the concentration of plasticizer and phosphate ions in bulk solution produce for measurement with high accuracy. In this study, was made 15 ml glass bottle containing 0.2 M H<sub>2</sub>SO<sub>4</sub> receiving phase membrane. prepared by mixing polyvinyl chloride ...
Six field trials were carried out to assess the performance of the Chemcatcher passive sampler alongside spot sampling for monitoring priority hydrophobic organic pollutants (polycyclic aromatic hydrocarbons (PAHs) and organochlorine pesticides) in a wide range of conditions in surface water. The trials were performed in three European rivers: Elbe (Czech Republic), Alna (Norway) and Meuse (Net...
The main objective of this study was to evaluate the performance of a model for simulating the uptake of various pesticides on passive air samplers (PAS). From 2006-2007 a series of PAS using XAD-resin were deployed at Egbert, a rural agricultural site in southern Ontario, Canada, to measure the uptake of pesticides for time periods ranging from two months to one year. A continuous increase in ...
