Investigating Usage Potential of Datura stramonium L. for Phytoremediation of 2,4-Dichlorophenol

Ium n this work, the phytoremediation potential of 2,4-Dichlorophenol (2,4-DCP) from soil and wetlands by L. (jimsonweed) was investigated. The medium of seedlings growing in a hydroponic system was adjusted to different Datura stramoniconcentrations (0.0, 75, 100, 125, 150, 175, 200, 225, 250 and 275 ppm) of 2,4-DCP. Four days later, the remediation rate of

2,4-DCP in the growth medium, and root-stem length, root-stem dry weight, lipid peroxidation (LPO), protein and photosynthetic pigment content of seedlings were evaluated. D. stramonium seedlings provided remediation of 2,4-DCP between 52-

78% at all concentrations. In addition, the 2,4-DCP treatments inhibited the root-stem lengths and dry weights of seedlings

compared to their controls, particularly at high doses such as 200-275 ppm, but not at low doses. The applications generally

increased protein and LPO content of roots and leaves slightly, but did not affect chlorophyll. The results show that D. stramonium has a high usage potential for phytoremediation of 2,4-DCP
