Passive sampling devices (PSDs) offer key benefits for monitoring of chemical water quality, but the uptake process of PSDs for hydrophilic compounds still needs to be better understood. Determining mass transfer coefficients of the water boundary la

Microbial biological control agents (MBCAs) against pests and diseases in crops are regarded as sustainable tools in integrated pest management. In the European Union, biological control should be preferred to conventional chemical methods if they pr

The use of single-phase passive samplers is a common method for sampling bioavailable concentrations of hydrophobic aquatic pollutants. Often such samplers are used in the kinetic stage, and in situ calibration is necessary. Most commonly, exchange k

Exchange kinetics of organic compounds between passive samplers and water can be partly or completely controlled by transport in the sorbent. In such cases diffusion models are needed. A model is discussed that is based on a series of cosines (space)

Field-based atrazine sampling rates (Rs ) obtained by the polar organic chemical integrative sampler (POCIS) method were measured in 9 headwater streams over 3 yr covering 5 to 6 exposure periods of 2 to 3 wk/site/yr. Rates were best in line with the

The effects of changing hydrodynamic conditions and changing temperatures on polar organic chemical integrative sampler (POCIS) sampling rates (Rs ) were investigated for 12 crop protection chemicals. Exposure concentration was held constant in each

Mass transfer coefficients of the water boundary layer (kw) were measured using alabaster dissolution kinetics in a diffusion cell that was operated at stirring rates between 90 min−1 and 600 min−1, aiming to provide a more robust characterizatio

Two laboratory performance studies with 21 and 11 participants were carried out for passive sampling of nonpolar chemicals in water, using silicone samplers that were deployed for 7 wk and 13 wk at 2 river sites in the Netherlands. Target analytes we

Contaminants in sewer overflows can contribute to exceedances of environmental quality standards, thus the quantification of contaminants during rainfall events is of relevance. However, monitoring is challenged by i) high spatiotemporal variability

A key success factor for the performance of passive samplers is the proper calibration of sampling rates. Sampling rates for a wide range of polar organic compounds are available for Chemcatchers and polar organic chemical integrative samplers (POCIS
