Field performance of the Chemcatcher passive sampler for monitoring hydrophobic organic pollutants in surface water.
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...
متن کاملCalibration and field evaluation of the Chemcatcher® passive sampler for monitoring metaldehyde in surface water.
Metaldehyde is a potent molluscicide. It is the active ingredient in most slug pellets used for crop protection. This polar compound is considered an emerging pollutant. Due to its environmental mobility, metaldehyde is frequently detected at impacted riverine sites, often at concentrations above the EU Drinking Water Directive limit of 0.1µgL-1 for an individual pesticide. This presents a prob...
متن کاملEvaluation of the Chemcatcher and DGT passive samplers for monitoring metals with highly fluctuating water concentrations.
Passive sampling devices accumulate chemicals continuously from water and can provide time weighted average (TWA) concentrations of pollutants over the exposure period. Hence, they offer a number of advantages over other conventional monitoring techniques such as spot or grab sampling. The diffusive gradient in thin film (DGT) and the Chemcatcher passive samplers can be used to provide TWA conc...
متن کاملA passive sampler based on solid-phase microextraction for quantifying hydrophobic organic contaminants in sediment pore water.
Sediment-quality assessment often is hindered by the lack of agreement between chemical and biological lines of evidence. One limitation is that the bulk sediment toxicant concentration, the most widely used chemical parameter, does not always represent the bioavailable concentration, particularly for hydrophobic organic compounds (HOCs) in highly contaminated sediments. In the present study, w...
متن کاملA New Film-Based Passive Sampler for Moderately Hydrophobic Organic Compounds.
Passive samplers for moderately hydrophobic organic compounds (MHOCs) (i.e., log Kow ranging from 2 to 5) are under-developed compared to those that target polar or strongly hydrophobic compounds. The goal of this study was to identify a suitable polymer and develop a robust and sensitive film-based passive sampler for MHOCs in aquatic systems. Poly(methyl methacrylate) (PMMA) exhibited the hig...
