QSAR modelling of soil sorption. Improvements and systematics of log KOC vs. log KOW correlations
Determination of octanol/water partition coefficients for hydrophobic organic chemicals with the “slow‐stirring” method
Experimental data are presented on octanol/water partition coefficients for 70 hydrophobic organic chemicals that were determined with a “slow-stirring” method. With this method, log Kow values can…
Modes of action in ecotoxicology: their role in body burdens, species sensitivity, QSARs, and mixture effects.
This review seeks to show the crucial role of target sites, interactions with the target site(s), and mechanisms for an adequate and efficient ecotoxicological risk assessment and recommends the use of internal effect concentrations and target site concentrations as a mixture toxicity parameter.
Equilibrium sampling devices.
These devices are part of an emerging strategy for monitoring exposure to hydrophobic organic chemicals and are designed to provide real-time information about human exposure to these chemicals.
Sensing Dissolved Sediment Porewater Concentrations of Persistent and Bioaccumulative Pollutants Using Disposable Solid-Phase Microextraction Fibers
Polymer coated glass fibers were applied as disposable samplers to measure dissolved concentrations of persistent and bioaccumulative pollutants (PBPs) in sediment porewater. The method is called…
A quantitative property-property relationship (QPPR) approach to estimate in vitro tissue-blood partition coefficients of organic chemicals in rats and humans
Signs for a possible role of tissue components other than lipid and water in the tissue-blood partitioning process of compounds were observed from the calibration results of the model.
Poly(dimethylsiloxane) as passive sampler material for hydrophobic chemicals: effect of chemical properties and sampler characteristics on partitioning and equilibration times.
Equilibration times are predicted for organic chemicals that vary in hydrophobicity and samplers with different dimensions and polymeric phases and a simple diffusion-based model illustrates that the exchange of chemicals was limited by diffusion through the aqueous diffusion layer surrounding the sampler.

A common task in data analysis is to model the relationships between two sets of variables, the descriptor matrixX and the response matrixY. A typical example in aquatic science concerns the…
Analysis of the Time-Dependent Acute Aquatic Toxicity of Organophosphorus Pesticides: The Critical Target Occupation Model
The model is based on the idea that, for chemicals exhibiting an irreversible receptor interaction, mortality is associated with a critical amount of “covalently occupied” target sites, i.e., the critical target occupation (CTO) and successfully describes the 1−14-d LC50(t) data of several phosphorothi...
