An in-situ assessment of low-density polyethylene and silicone rubber passive samplers using methods with and without performance reference compounds in the context of investigation of polychlorinated biphenyl sources in rivers

Luiz Felippe De Alencastro, Nicolas Estoppey, Adrien Schopfer, Camille Fong

This study firstly aims to assess the field performances of low density polyethylene (LDPE) and silicone rubber (SR) samplers for the monitoring of polychlorinated biphenyls (PCBs) in water regarding the uptake, the sam- pling rate (RS) estimated by using ...

Evaluation of performance reference compounds (PRCs) to monitor emerging polar contaminants by polar organic chemical integrative samplers (POCIS) in rivers

Dominique Grandjean, Luiz Felippe De Alencastro, Nicolas Estoppey, Adrien Schopfer, Maria Inmaculada Carpinteiro Botana, Camille Fong

In this work, a method combining polar organic chemical integrative samplers (POCIS) and ultraperformance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS) was assessed for the determination of two corrosion inhibitors (benzotriazole ...

Low density polyethylene (LDPE) passive samplers for the investigation of PCB point sources in rivers

Luiz Felippe De Alencastro, Nicolas Estoppey, Julien Omlin, Adrien Schopfer

This study aims to provide a passive sampling approach which can be routinely used to investigate polychlorinated biphenyl (PCB) sources in rivers. The approach consists of deploying low density polyeth- ylene (LDPE) strips downstream and upstream of poten ...

The Use of Passive Samplers to Reveal Industrial and Agricultural Pollution Trends in Swiss Rivers

Luiz Felippe De Alencastro, Nicolas Estoppey, Julien Omlin, Adrien Schopfer, Robin Udrisard

This study shows the efficiency of passive sampling to reveal industrial and agricultural pollution trends. Two practical applications for nonpolar and polar contaminants are presented. Low-density polyethylene (LDPE) samplers were deployed for one year in ...

Effect of water velocity on the uptake of polychlorinated biphenyls (PCBs) by silicone rubber (SR) and low-density polyethylene (LDPE) passive samplers. An assessment of the efficiency of performance reference compounds (PRCs) in river-like flow conditions

Luiz Felippe De Alencastro, Nicolas Estoppey, Julien Omlin, Adrien Schopfer

One aim of this study is to determine the impact of water velocity on the uptake of indicator polychlorinated biphenyls (iPCBs) by silicone rubber (SR) and low-density polyethylene (LDPE) passive samplers. A second aim is to assess the efficiency of perfor ...
