Fig. 1From: Reduction of soil contamination by cypermethrin residues using phytoremediation with Plantago major and some surfactantsEfficiency of solubility-enhancing agents (SiO2, HPβCD, HA and Tw 80) in phytoremediation of CYP contaminated soil using PM through 1–14 days of exposure. a CYP in soil, b CYP in roots, c CYP in leaves. Means and standard deviations of three replicates indicate significant differences (p < 0.05). CCSS, CYP-contaminated sterilized soil; CCS, CYP-contaminated soil; PM, (Plantago major); SiO2, liquid silicon dioxide; HPβCD, 2-hydroxypropyl-beta-cyclodextrin; HA, liquid humic acid; Tw80, Tween 80Back to article page
