Determination of equilibrium and rate constants for binding of a polychlorinated biphenyl congener by dissolved humic substances

Reviews of Environmental Contamination and Toxicology

“…This avoids the need for gas phase analysis. Hassett and Millicic (1985), and Yin and Hassett (1986) have developed a similar system which is suitable for measuring the HLCs in natural waters.…”

Subsurface flow and transport of organic chemicals: an assessment of current modeling capability and priority directions for future research (1987-1995)

“…Dissolved organic chemicals that move in saturated groundwater systems can also enter into chemical reactions with other aqueous inorganic and dissolved organic constituents (Westall et al 1985;Hassett and Milicic 1985;Haas and Kaplan 1985;McCarthy and Jimenez 1985). However, there is a lack of thermodynamic data for reactions involving organ1cs relative to that for inorganics.…”

Solid-Phase Microextraction for the Evaluation of Partition Coefficients of a Chlorinated Dioxin and Hexachlorobenzene into Humic Substances

“…[6][7][8][9] To quantify the partition of HOPs into HSs, researchers have evaluated the partition coefficients of HOPs into HSs (Koc) by measuring the unbound and bound species of HOPs with HSs. Some methods have been reported on the speciation analyses of HOPs in the presence of HSs: e.g., liquid-liquid extraction, [10][11][12] dialysis, 1,6,13,14 fluorescence quenching, 5,15-18 solubility enhancement [19][20][21][22] and solid-phase extraction. 9,23,24 However, there were some problems in these methods: e.g., using large amounts of organic solvents, chemicals and sample solutions, and direct exposure of the analysts to hazardous chemicals.…”
