Polar organic chemical integrative samplers as an effective tool for chemical monitoring of surface waters-Results from one-year monitoring in France

B. Mathon et al.

Summary: This study demonstrates the advantages and limitations of using passive samplers for monitoring polar contaminants in surface waters. The results show that POCIS has a higher quantification frequency for most contaminants compared to spot samples, and it lowers the limits of quantification. POCIS is able to capture short-duration and high-intensity contamination events, and it provides more reliable annual monitoring and assessment of environmental quality compared to spot sampling.

Sensitivity improvement of o-DGT for organic micropollutants monitoring in waters: Application to neutral pesticides

Rachel Martins de Barros et al.

Summary: In this study, the larger configuration of o-DGT, known as Lo-DGT, was evaluated and found to increase sensitivity compared to conventional o-DGT. Both laboratory and field evaluations of Lo-DGT were conducted for the sampling of 24 model neutral pesticides and metabolites. The results showed that Lo-DGT had a 4.8-fold increased sampling area, allowing for higher quantification frequency and lower LOQ compared to conventional o-DGT. Both devices were found to be reliable for monitoring water quality, but Lo-DGT provided a better assessment due to its lower LOQ.

Diffusive gradients in thin films (DGT): A suitable tool for metals/metalloids monitoring in continental waterbodies at the large network scale

Juliette Rougerie et al.

Summary: The contribution of DGT to continental water quality monitoring was evaluated in a real measurement network, showing robust field deployments and higher quantification frequency for certain elements compared to grab sampling. Despite the higher cost, the use of DGT sampling provides different but complementary information for water quality assessments, making it a valuable tool for improving monitoring networks.
