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

Luiz Felippe De Alencastro, Julien Omlin, Nicolas Estoppey, 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, Julien Omlin, Nicolas Estoppey, 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, Julien Omlin, Nicolas Estoppey, 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 ...

Direct photolysis of human metabolites of the antibiotic sulfamethoxazole: Evidence for abiotic back-transformation

Florence Bonvin, Julien Omlin, Tamar Kohn, Rebecca Rutler, Timothy Strathmann

The presence of potentially persistent and bioactive human metabolites in surface waters gives rise to concern; yet little is known to date about the environmental fate of these compounds. This work investigates the direct photolysis of human metabolites o ...
