Effects of humus on environmental mobility of mineral bound mercury
腐殖酸对矿物结合汞环境迁移性的影响及其机制研究

Humus including fulvic acid, brown humic acid and grey humic acid had either suppressing or activating effects on the environmental mobility such as atmospheric volatilization, soil vertical transport and plant uptake of five types of mineral bound Hg(Fe_2O_3-Hg, MnO_2-Hg, CaCO_3-Hg,kaolinite-Hg and bentonite-Hg). Fulvic acid could dramatically promote the environmental mobility of Fe_2O_3-Hg and MnO_2-Hg, while acid leaching could accelerate such activating processes of fulvic acid acted on silicate mi...
