Overview of the Chemcatcher® for the passive sampling of various pollutants in aquatic environments Part A: Principles, calibration, preparation and analysis of the sampler

Overview of the Chemcatcher® for the passive sampling of various pollutants in aquatic environments Part B: Field handling and environmental applications for the monitoring of pollutants and their biological effects

“…Aguilar-Martìnez et al [15] suggested the use of blanks in order to control possible contamination from these different preparation and exposure steps. Authors used two types of blanks: procedural blanks to estimate the contamination arising from steps (1) to (4), and field blanks to account for additional contamination during steps (5) and (6). Procedural blanks were also used to determine the initial concentrations of PRCs (Performance and Reference Compounds) [9,38].…”

“…In order to use this sampler as a quantitative tool, a calibration step is needed to determine sampling rates. R s are calculated as shown in Charriau et al [4] (Section 2.2) and are then used to determine TWACs for Chemcatcher s field applications.…”

“…In Part A [4], we covered all the preparation, and analysis procedures, including the wide range of contaminants which could be sampled with the Chemcatcher s . The large variety of available materials (membranes and disks) was detailed for the various sampler configurations.…”

Salinity and pH as factors affecting the passive sampling and extraction of pharmaceuticals from water

“…The passive sampling of pharmaceuticals from water is an interesting alternative to traditional grab sampling and is suitable for long-term monitoring [1][2][3]. POCIS (Polar Organic Chemical Integrative Sampler) and Chemcatcher [4] are the best known and most used for this purpose. Both techniques of sampling utilize a solid sorbent as the receiving phase, namely a copolymer of styrene, vinylbenzene, and vinylpyrrolidone (the equivalent of hydrophilic-lipophilic balanced (HLB) conditions of the water donor phase (temperature, conductivity, organic matter content, flow, and more) in the tested water environment are often different from those obtained in the laboratory tests.…”

Improving Toxicity Assessment of Pesticide Mixtures: The Use of Polar Passive Sampling Devices Extracts in Microalgae Toxicity Tests

“…It was the object of recent and extensive reviews (Charriau et al, 2016; Lissalde et al, 2016). Briefly, its polar configuration consists of a one-side opening housing (exposure area between 14.5 and 17.5 cm 2 depending on the evoluting design) that includes a Empore disk receiving phase (C18 or SDB-XC or SDB-RPS) and an optional membrane (PES 0.1–0.45 μm pore size).…”
