Henry's law constants for 11 polychlorinated biphenyls (PCBs) were measured using a gas purge system at 20 °C. The studied PCB congeners ranged from 2,4,4‘-trichlorobiphenyl to 2,2‘,3,4,4‘,5,5‘-heptachlorobiphenyl, spanning a range of hydrop

The long-term sediment—water distribution of polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), spiked to Lake Ketelmeer (The Netherlands) sediment, was studied using a gas-purge technique. Contact times varied from 2 to

Aqueous solubilities, n-octanol/water partition coefficients (K ow s), and Henry's law constants were determined for a range of polycyclic aromatic hydrocarbons (PAHs) using a generator-column, slow-stirring, and gas-purge method, respectively. The c

We determined the maximum amounts of added phenanthrene, chrysene, and 2,5-dichlorobiphenyl sorbed onto high-energy adsorption sites in a sediment on bi-solute experiments. The bi-solute pairs were phenanthrene/chrysene and phenanthrene/2,5-dichlorob

We determined the maximum amount of added phenanthrene that could be adsorbed in the very slow desorption domain of 16 sediments and soils with and without native compounds present. The differences in the amount of phenanthrene taken up in this domai

The desorption kinetics of hexachlorobenzene (HCB) and 2,4,4'-trichlororbiphenyl (PCB 28) spiked to a field sediment were studied using a gas-purge technique. A contact time of up to 1,461 d was used to assess long-term changes in desorption kinetics

The maximum amounts of phenanthrene that can be taken up in both the slowly desorbing domain and the very slowly desorbing domain of 19 soils and sediments were determined by measuring the desorption of phenanthrene added at high loadings associated

The maximum amounts of phenanthrene that can be adsorbed in both the slowly desorbing domain and the very slowly desorbing domain of two sediments were determined. To this end, native compounds were removed by mild solvent extraction, heating, or ext

A study was performed on the influence of the addition of a relatively large amount of phenanthrene to two in situ contaminated sediments on the fractions of native PAHs in both the slowly desorbing domain and the very slowly desorbing domain in comp

To be able to predict the degradation (rate) of organic chemicals (e.g. pesticides) in the field, knowledge of the environmental conditions that are of influence on the degradation process are of importance. In the present study an experimental syste
