Speech Title "Conservation Soil Resources from Heavy metal Contamination with Economy Generation Phytoremediation Technologies"
Soil contamination with heavy metals has a significant risk to human health，because of their toxicity, mobility and long-lasting effects on soil quality and the ecosystems. Currently, physicochemical soil remediation techniques such as soil washing, incineration, solidification, thermal desorption, and disposal as waste are mainly used for contaminated soil treatment. However, these methods are usually need extremely high cost, destroy the properties of soils resulting in loss of soil resources. There is a great need to develop effective technologies for treatment of soil contaminated soils as recoverable soil resources.
In this study, we developed an economy generation green technology with resources plants, which can do phytoremediation of contaminated soils as well as generate economic incomes to the owners of the contamination sites, by growing resources crops for biofuel production or as the market ornamental flowers.
To test the feasibility of the strategy, we conducted field experiments by using biofuel crops such as Sorghum bicolor, Zea mays as well as ornamental flowers such as Chrysanthemum morifolium. The results showed that phytoremediation using biofuel resourceful plants worked effectively for soil remediation, and generated well economic income to the owners of contaminated sites. It also showed that the resources crops were easy for management, produced large biomass and had comparable remediation rates to some special hyperaccumulator plants. This study indicates that the strategy is a reasonable choice for remediation of heavy metal soil contaminated sites. (This study was supported by JSPS KAKENHI No.16H05633).
