β-Cyclodextrin enhanced bioavailability of petroleum hydrocarbons in industrially contaminated soil: A phytoremediation field study.
Low remediation efficiency due to low bioavailability is a primary restrictive factor for phytoremediation applications. Specifically, this investigation examines whether Suaeda heteroptera Kitagawa (S. heteroptera) can be used in combination with β-cyclodextrin (β-CD) to remediate contaminated site. The study was conducted on the growth response of S. heteroptera, bioavailability and dissipation of petroleum hydrocarbons (PHs) in soil under the influence of β-CD Our preliminary studies confirmed that β-CD is effective in increasing the biomass and height of plants. The presence of β-CD could dramatically elevate polycyclic aromatic hydrocarbons (PAHs) and n-alkanes in S. heteroptera. Moreover, a remarkable positive correlation between PHs levels in roots with the dosage of β-CD and a negative correlation between the PHs levels in roots with KOW of PHs have been observed. The dissipation of n-alkanes was estimated to be 38.73-62.27%, and the dissipation of PAHs was 36.59-60.10%. In addition, the dissipation behavior of n-alkanes and PAHs was well agreement with the first-order kinetic model. These results display that applying β-CD accelerated the desorption process of PHs from soil and promoted the absorption process of PHs onto the root epidermis. The enhancement of phytoremediation was achieved by increasing the bioavailability of PHs.
期刊介绍:
The International Journal of Phytoremediation (IJP) is the first journal devoted to the publication of laboratory and field research describing the use of plant systems to solve environmental problems by enabling the remediation of soil, water, and air quality and by restoring ecosystem services in managed landscapes. Traditional phytoremediation has largely focused on soil and groundwater clean-up of hazardous contaminants. Phytotechnology expands this umbrella to include many of the natural resource management challenges we face in cities, on farms, and other landscapes more integrated with daily public activities. Wetlands that treat wastewater, rain gardens that treat stormwater, poplar tree plantings that contain pollutants, urban tree canopies that treat air pollution, and specialized plants that treat decommissioned mine sites are just a few examples of phytotechnologies.
