Bioavailability of zinc oxide nano particle with fly ash soil for the remediation of metals by Parthenium hysterophorus

Abstract

To investigate the interaction of zinc oxide nanoparticles (ZnO NPs) with fly ash soil (FAS) for the reduction of metals from FAS by Parthenium hysterophorus were studied. The average accumulation of metals by P. hysterophorus stem were Fe 79.6%; Zn 88.5%; Cu 67.5%; Pb 93.6%; Ni 43.5% and Hg 39.4% at 5.5 g ZnO NP. The concentration of ZnO NP at 1.5 g did not affect the metals accumulation, however at 5.5 g ZnO NP showed highest metal reduction was 96.7% and at 10.5-15.5 g ZnO NP of 19.8%. The metal reduction rate was R max for Fe 16.4; Zn 21.1; Pb 41.9; Hg 19.1 was higher than Ni 6.4 and Cu 11.3 from the FAS at 5.5 g ZnO NP whereas, the reduction rate of Pb showed highest. With doses of 5.5 g ZnO NP the biomass increased upto 78%; the metal reduced upto 98.7% with the share of 100% ZnO NP from FAS. Further investigation with phytotoxicity the plant reactive oxygen species (ROS) production were affected due was mainly due to the recovery of metals from FAS (R2 = 0.99).

Typha Latifolia L. Grown in Carrying Petroleum Secondary Effluent Supply Nutrients Enhance for Biomass Growth and Phytoremediation of Heavy Metals and TPH

“…Bioaccumulation of TPH and HMs in biomass to transfer via transportation index (TI) can be considered as an effective tool for identi cation of hyper accumulator species. The uptake of metals from soil to plants and then translocation those to aerial parts allow to determine the capabilities of individual species to accumulate the metals and therefore to recognized as a potential hyper accumulator (Rana and Maiti, 2018;Ahmad et al 2020). The TIs changed between 0.65 to 2.95 for HMs and for TPH between 1.15 to 3.45 from 25-75% dosing of PSE, whereas at decrease at 100% compared to control (Table 3).…”

“…The mean TI for Cd, Co and Mn in T. latifolia L. was higher than 2.56 at 75% dosing of PSE, but mean TI for higher dosing metals were generally lower due to toxicity and did not effectively transfer heavy metals from root to plant body (Table 3). The TPH for TI at 75% dosing was 3.45 compared to higher dosing lower transfer due to availability with plants parts (Foshtomi et al 2019;Ahmad et al 2020). The plant parts having ability was in the order of TPH>Co>Cd>Mn.…”

“…The high concentration of TPH and HMs in T. latifolia L tissue could decrease the growth, biomass (Waheed et al 2019;Ahmad et al 2020). The reduction in biomass of plants at 100% might be due to toxicity of TPH and HMs, which corroborates our previous results using varying concentrations of HMs on growth of rye grass plants (Ahmad et al 2019).…”

“…It also depends on soil factors such as metal mobility and crucially, soil metals with wastes amendment and phytoavailability (Klomjek, 2016;Muthusaravanan et al 2018;Zhaoet al 2020). After all, rather than total concentrations, a major factor governing the phytotoxicity of metals in soil is their bioavailability (Pandey, 2017;Li et al 2018;Prabakaran et al 2019;Ahmad et al 2020). Several aquatic and terrestrial plants is identi ed as a species able to phytoextraction of metals, nutrients and petroleum haydrocarbon from a multiply contaminated soil (Mustapha and Lense, 2018), take up and accumulate into its above-ground parts stem for the metals such as Cd, Co, Cu, Ni, Mn, Pb and TPH (Galal et al 2017).…”
