Solution culture experiments on effects of humus (Fulvic acid, Brown humic acid, Grey humic acid) on the plant activity of mineral bound Hg (CaCO3-Hg, Fe2O3-Hg, MnO2-Hg, bentonite-Hg and kaolinite-Hg) were carried out; and soil was used in confirmed test.

• 以植物水培试验就腐殖酸（富里酸、棕色胡敏酸和灰色胡敏酸）对矿物结合汞（CaCO3－Hg，Fe2O3-Hg，MnO2-Hg，膨润土-Hg，高岭土-Hg）的植物活性的影响进行了探讨，并以土壤作印证试验.
