Polyethylene devices and the effects of sediment resuspension on the cycling of PAHs and PCBs in the lower Hudson Estuary
… on the sediment bed-to-water column transport of hydrophobic organic contaminants (HOCs) in the lower Hudson Estuary, the following areas of research were pursued: 1) a passive, in situ sampler, a polyethylene device (PED), for measuring HOCs in the aquatic environment was developed; 2) the …

Isotopic constraints on the sources and associations of organic compounds in marine sediments
… a new perspective on the fate of both natural organic matter and hydrophobic organic contaminants (HOCs) in marine sediments, we have investigated the relationship between radiocarbon (14C) age and the different modes of association in aquatic sediments and soils. Radiocarbon is a sensitive …

Modeling The Impact Of Sediment Resuspension And Flocculation On The Fate Of Polychlorinated Biphenyls
Hydrophobic organic contaminants (HOCs) are important pollutants in urban estuaries. HOCs include polycyclic aromatic hydrocarbon (PAH), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs). Sorption to resuspended particles and sediments plays an important role controlling …

Sediment-water exchange of polycyclic aromatic hydrocarbons in the lower Hudson Estuary
… (PEDs), which rely on the partitioning of hydrophobic organic contaminants (HOCs) between water and polyethylene, were shown to be useful for the measurement of dissolved HOCs like polycyclic aromatic hydrocarbons (PAHs) in natural waters. These PEDs allow for the measurement of the …

The science behind Tenax extractable concentrations and their use in evaluating environmental risk
… exposure estimates and subsequent risk of hydrophobic organic contaminants (HOCs) in aquatic sediments requires measuring the bioavailable and/or bioaccessible concentration in sediment; as total extractable concentrations have not been found to produce accurate results. Organic carbon …

Combined effects of bioavailable organic contaminants in the aquatic environment.
… bioavaialable) concentrations of a wide range of organic contaminants in water. At the same time, techniques for partitioning controlled delivery (passive dosing; PD) promise to overcome many of the challenges associated with toxicity testing of hydrophobic substances, which can bias the …
