Comparative phytoremediation potentials of Impatiens balsamina L. and Crotalaria retusa L. for soil contaminated with used lubricating

The aim of this study was to investigate the phytoremediation potentials of Crotalaria retusa L. and Impatiens balsamina for ULO contaminated soil. A randomized block pot experiment was conducted for each species under plant house conditions in soil contaminated with ULO at a concentration of 5,000 mg kg− 1 (0.5% w/w)-30,000 mg kg− 1 (3% w/w).
