The solubilization of hydrophobic organic pollutants from soil is important for the phytoremediation of contaminated soil. In this study, we used perylene as a model pollutant to evaluate the abilities of 11 organic acids to solubilize hydrophobic compounds from soil. Oxalic acid and citric acid showed high solubilization abilities, and when added to soil, they enhanced perylene uptake into Cucurbita pepo, likely owing to the chelating ability of these acids.
