Phytoremediation: Data on effects of titanium dioxide nanoparticles on phytoremediation of antimony polluted soil.

ABSTRACT: This data article presents effects of titanium dioxide nanoparticles (TiO₂ NPs) on phytoremediation of antimony contaminated soil using S. Bicolor in detail. Seedlings of S. bicolor were exposed to different doses of TiO₂ NPs (0,50,100,250,500 and 1000 mg/kg) in plastic pots containing Sb-contaminated soil and cultivated over a 80-day period in a greenhouse. Harvested plants were dried in an oven at 70 °C for 48 h to obtain dry weight of the biomass. The concentrations of metal(loid)s in soil as well as in plant organs were determined by inductively coupled plasma optical emission spectrometry (ICP-OES). Chlorophyll contents of fresh leaves materials were measured by UV spectrophotometry at 645 nm and 663 nm. Data on distribution of Sb and Ti in roots and shoots of S. bicolor contaminated soil treated with different levels of TiO₂ NPs are indicated in tables. Figures presented the data on plant growth behavior, Sb and Ti accumulation capacities, and physiological response of S. Bicolor in various treatments. The presented data are beneficial to gain insight into phytoremediation potential of S. bicolor in Sb-contaminated soil as well as plant behavior under the stress of both Sb and TiO₂ NPs in soil. These data are useful for environmental researchers, soil and plant scientists, nanotechnology experts, stakeholders and decision-makers involved in soil decontamination challenges.

Project description:Plant-microbe interactions are considered to be important processes determining the efficiency of phytoremediation of petroleum pollution, however relatively little is known about how these interactions are influenced by petroleum pollution. In this experimental study using a microcosm approach, we examined how plant ecophysiological traits, soil nutrients and microbial activities were influenced by petroleum pollution in Phragmites australis, a phytoremediating species. Generally, petroleum pollution reduced plant performance, especially at early stages of plant growth. Petroleum had negative effects on the net accumulation of inorganic nitrogen from its organic forms (net nitrogen mineralization (NNM)) most likely by decreasing the inorganic nitrogen available to the plants in petroleum-polluted soils. However, abundant dissolved organic nitrogen (DON) was found in petroleum-polluted soil. In order to overcome initial deficiency of inorganic nitrogen, plants by dint of high colonization of arbuscular mycorrhizal fungi might absorb some DON for their growth in petroleum-polluted soils. In addition, through using a real-time polymerase chain reaction method, we quantified hydrocarbon-degrading bacterial traits based on their catabolic genes (i.e. alkB (alkane monooxygenase), nah (naphthalene dioxygenase) and tol (xylene monooxygenase) genes). This enumeration of target genes suggests that different hydrocarbon-degrading bacteria experienced different dynamic changes during phytoremediation and a greater abundance of alkB was detected during vegetative growth stages. Because phytoremediation of different components of petroleum is performed by different hydrocarbon-degrading bacteria, plants' ability of phytoremediating different components might therefore vary during the plant life cycle. Phytoremediation might be most effective during the vegetative growth stages as greater abundances of hydrocarbon-degrading bacteria containing alkB and tol genes were observed at these stages. The information provided by this study enhances our understanding of the effects of petroleum pollution on plant-microbe interactions and the roles of these interactions in the phytoremediation of petroleum-polluted soil.
