Influence of chemical characteristics of humic substances on the partition coefficient of a chlorinated dioxin.
Fumiko Tanaka,Masami Fukushima,Atsunori Kikuchi,Hikaru Yabuta,Hiroyasu Ichikawa,Kenji Tatsumi +5 more
TL;DR: Results show that the Koc values for HpCDD are significantly influenced by the polarity of HSs.

Separation of fulvic acid from soil extracts based on ion-pair formation with a cationic surfactant.
TL;DR: The results show that FA-SUR is more polar and hydrophilic than FA-DAX, which could be due to alcoholic hydroxyl groups and polysaccharides as well as carboxylic groups.

Water Solubility Enhancement Effects of Some Polychlorinated Organic Pollutants by Dissolved Organic Carbon from a Soil with a Higher Organic Carbon Content
Masami Fukushima,Yasuaki Tanabe,Hikaru Yabuta,Fumiko Tanaka,Hiroyasu Ichikawa,Kenji Tatsumi,Akira Watanabe +6 more
TL;DR: It is suggested that, in a soil with a higher OC content, the HA can serve as more effective carrier of PCOPs from the soil to an aquatic environment when the larger quantities of PCops that are partitioned into the HA are able to dissolve in the aqueous phase.

Solid-Phase Microextraction for the Evaluation of Partition Coefficients of a Chlorinated Dioxin and Hexachlorobenzene into Humic Substances
TL;DR: A method for the evaluation of the partition coefficients (K(oc)) of hexachlorobenzene (HCB) and 1,2,3,4,6,7,8-heptachlorodibenzo-p-dioxin (HpCDD) into humic substances (HSs) by using solid-phase microextraction (SPME).

Hikaru Yabuta,Masami Fukushima,Mikio Kawasaki,Fumiko Tanaka,Takayuki Kobayashi,Kenji Tatsumi +5 more
TL;DR: In this paper, the structural factors associated with free radicals in humic substances (HSs) with lower degrees of humification that are comparable to Type Rp, correlations between free radical content and chemical properties of 10 humic acids (HAs) and 2 fulvic acids (FAs) from different sources were investigated.
