Department of Environmental Sciences, Wageningen University, The Netherlands
Environ Sci Technol 35:3742-8. 2001

Institute for Risk Assessment Sciences, Utrecht University, P O Box 80176, 3508 TD Utrecht, The Netherlands
Environ Sci Technol 40:3829-35. 2006
..Consequently, weathered oil probably is the ultimate sedimentary sorbent for PCBs and should be included in HOC fate models...

Modeling maximum adsorption capacities of soot and soot-like materials for PAHs and PCBsPaul C M Van Noort
Institute for Inland Water Management and Wastewater Treatment RIZA, P O Box 17, 8200 AA Lelystad, The Netherlands
Environ Sci Technol 38:3305-9. 2004
..Maximum adsorption capacities decreased by 1-2 orders of magnitude as the contact area increased by 50%. This points to adsorption sites being hardly larger than sorbates...
Sorption of polycyclic aromatic hydrocarbons to oil contaminated sediment: unresolved complex?Michiel T O Jonker
