Risk-management tool for environmental prioritization of pharmaceuticals based on emissions from hospitals

Over the past decade, the health care sector has becomeincreasingly aware of the impact of pharmaceutical emissions to the environment. Yet, it remains unclearwhich compounds are the most relevant to address and at what point emission control is most effective. This study presents a modelling framework to prioritize pharmaceuticals based on...

Partitioning of hydrophobic organic contaminants between polymer and lipids for two silicones and low density polyethylene

Polymers are increasingly used for passive sampling of neutral hydrophobic organic substances (HOC) in environmental media including water, air, soil, sediment and even biological tissue. The equilibrium concentration of HOC in the polymer can be measured and then converted into equilibrium concentrations in other (defined) media, which however...

Strategic monitoring to account for rapid variations in the nitrate concentration of groundwater and surface water

As part of two PhD projects, we installed ion-selective electrodes and passive samplers for monitoring nitrate concentrations in a 7 km 2 catchment and compared the results to grab samples. We also monitored nitrate concentrations at the catchment outlet. We tested the effectiveness of these monitoring approaches to estimate the long-term...
