Inhalt: "Advances in Microbe-assisted Phytoremediation of Polluted Sites provides a comprehensive overview of the use of phytoremediation to decontaminate polluted land through microbial enhanced phytoremediation, including the use of plants with respect to ecological and environmental science. The book discusses the potential of microbial-assisted phytoremediation of the contaminant, including heavy metals, pesticides, polyaromatic hydrocarbons, etc., with case studies as examples. Key subjects covered include plant-microbe interaction in contaminated ecosystems, microbe-augmented phytoremediation for improved ecosystem services, and success stories on microbe-assisted phytoremediation of contaminated sites."--
