Phytoextraction of Cr(VI)-Contaminated Soil by Phyllostachys pubescens: A Case Study

This work presents the results of experimental tests to evaluate the effects of prolonged contamination by Cr on Moso Bamboo (MB) (Phyllostachys pubescens) and the adaptability of the MB to the Mediterranean climate. A preli...

A preliminary test on the <i>MB</i> was developed in the laboratory, simulating irrigation under Mediterranean conditions (600 mm per year) and tropical conditions (1800 mm per year), to evaluate the rate of growth and the <i>MB</i>’s capability for Cr phytoextraction from contaminated soil. The tolerance of <i>MB</i> to Cr was also performed showing a good response of the plant to 100 mg Cr/L solution, utilized for irrigation of the pots. The results show that the rate of <i>MB</i>’s removal of Cr from soil ranged from 49.2% to 61.7% as a function of the soil degree of contamination, which varied from approx. 100 mg/kg to 300 mg/kg. The distribution of Cr in the various sections of the bamboo revealed that the greater percentage was present in rhizomes: 42%, equal to 114 mg Cr for 600 mm per year, and 50%, equal to 412 mg Cr for 1800 mm per year. A noteworthy diffusion of the metal towards the outermost parts of the plant was shown. The values of Cr retained in the stems and leaves of <i>MB</i> tissues were quite high and varied from 1100 mg/kg to 1700 mg/kg dry weight.Ezio RanieriGianfranco D’OnghiaFrancesca RanieriAndrea PetrellaVincenzo SpagnoloAda Cristina RanieriMDPI AGarticlebamboo growthtoleranceCr removalmetal translocationphytoextraction<i>Moso bamboo</i>Chemical technologyTP1-1185ENToxics, Vol 9, Iss 312, p 312 (2021)
