Available in PDF, EPUB and Kindle. Book excerpt: Heavy metal toxicity in aquatic sediments increases over time because inorganic contaminants are not biodegradable. Phytoremediation of industrial waste is becoming common practice. However, there is limited research to characterize phytoremediation by native plants to better understand pollutant remediation in existing wetlands and for wetland restoration. In southern California, stormwater runoff now constitutes the largest contributor of heavy metals to waterways and the ocean. Recent research has shown that microbial activity in the root zone of wetland plants can enhance phytoremediation of heavy metals. The goal of this study was to identify native wetlands plants that demonstrate a strong relationship with the soil microbial community and then evaluate their potential to immobilize heavy metal pollution in natural settings. During a year-long field study, hydrologic conditions, sediment, soil pore water and plant tissue associated with five native wetland plants along a two-mile stretch of the Santa Margarita River in southern California were analyzed for oxidation-reduction potential, dissolved organic carbon, microbial biomass and activity, and heavy metals (Cr, Cu, Pb, and Zn) content. Salix lasiolepis had significantly higher concentrations of all heavy metals in its associated sediment compared to other species. Soil organic matter was strongly correlated with metal content in the sediment and S. lasiolepis had twice as much soil organic matter as the other species. Schoenoplectus californicus had significantly more Cr in leaf tissue than other species. Subsequently, S. lasiolepis and S. californicus were tested in a greenhouse experiment for immobilization and uptake of Cr. Though soil organic matter was the same among all pots in the greenhouse experiment, the same results were found. S. lasiolepis immobilized more Cr in the soil and S. californicus had more Cr in leaf tissue. Immobilization of Cr in soil from S. lasiolepis pots was associated with more reducing soil conditions and an anaerobic, metal-reducing soil microbial community. S. californicus plants was associated with more oxidized soil conditions, a more aerobic soil microbial community and greater uptake of Cr into leaf tissue. These findings suggest that S. lasiolepis is a good candidate for further study of heavy metal phytoremediation in riparian wetlands.

This book was released on 2014 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study suggests that there is some potential for phytoremediation of PCBs and chlorinated dioxins/furans. The results for petroleum hydrocarbons were inconclusive. Metal uptake was not substantial enough to lower metal concentrations in the soils. Thus phytoremediation of COIs at the site is limited and more aggressive forms of remediation may be required to reduce the concentrations of COIs quickly.

This book was released on 2019-06-29 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: ​The risks and consequences of environmental change are increasing, leading to massive losses in terms of ecosystems and having a huge impact on human populations. As such, global thinkers, environmentalists, scientists and policy makers are focusing on finding solutions and ways to sustain life on Earth. Anthropogenic impacts on the climate system can only be mitigated by the restoration of existing natural resources and the sustainable development of the environment and society. This book discusses the potential of green technology in waste management, wetland restoration, presenting the latest developments in the field of bioenergy, green ecology, bioremediation and microbial management. Wetlands are one of Earth’s most important ecosystems, and they provide valuable services to human societies, such as minimizing the impacts of floods, acting as a carbon sink, and offering water purification as well as recreational opportunities. Wetlands may be natural or constructed, and the effectiveness of wetland services largely depends on the diversity of macrophytes affecting the algal production, plant biomass and nutrient status of the system. In addition, they are one of the richest microbial ecosystems on earth: the rhizosphere, soil and water interface enhances wetland services with implications ranging from phytoremediation to microbial bioprospection. However, in order to function properly, they need to be effectively redesigned, reengineered, protected and maintained. The book addresses the dynamic relation between three global concerns: environmental pollution, resource exploitation and sustainability. It describes the utilization of resources like wastes (municipal, industrial, agricultural, mine drainage, tannery, solid, and e waste), plants, algae and microbes for production of renewable biofuel, biofertilizers and other value added products to achieve the goal of sustainable development. The book also discusses the current and future trends in employing wetlands in improving water quality. In addition it presents the latest international research in the fields of wetland science, waste management, carbon sequestration and bioremediation. Highlighting a broad spectrum of topics and strategies for achieving a sustainable environment, the book offers researchers, students and academics insights into utilizing resources in a sustainable way.
