Download or read book Soil Remediation and Plants written by Khalid Hakeem and published by Academic Press. This book was released on 2014-08-29 with total page 771 pages. Available in PDF, EPUB and Kindle. Book excerpt: The soil is being contaminated continuously by a large number of pollutants. Among them, heavy metals are an exclusive group of toxicants because they are stable and difficult to disseminate into non-toxic forms. The ever-increasing concentrations of such pollutants in the soil are considered serious threats toward everyone’s health and the environment. Many techniques are used to clean, eliminate, obliterate or sequester these hazardous pollutants from the soil. However, these techniques can be costly, labor intensive, and often disquieting. Phytoremediation is a simple, cost effective, environmental friendly and fast-emerging new technology for eliminating toxic heavy metals and other related soil pollutants. Soil Remediation and Plants provides a common platform for biologists, agricultural engineers, environmental scientists, and chemists, working with a common aim of finding sustainable solutions to various environmental issues. The book provides an overview of ecosystem approaches and phytotechnologies and their cumulative significance in relation to solving various environmental problems. Identifies the molecular mechanisms through which plants are able to remediate pollutants from the soil Examines the challenges and possibilities towards the various phytoremediation candidates Includes the latest research and ongoing progress in phytoremediation

Download or read book Water and Nutrient Management in Natural and Constructed Wetlands written by Jan Vymazal and published by Springer Science & Business Media. This book was released on 2010-09-23 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural and constructed wetlands play a very important role within the landscape and their ecological services are highly valuable. Water management, including flood water retention, biomass production, carbon sequestration, wastewater treatment and as a biodiversity source are among the most important ecological services of wetlands. In order to provide these services, wetlands need to be properly evaluated, protected and maintained. This book provides results of the latest research in wetland science around the world. Chapters deal with such topics as the use of constructed wetlands for treatment of various types of wastewater, use of constructed wetlands in agroforestry, wetland hydrology and evapotranspiration, the effect of wetlands on landscape temperature, and chemical properties of wetland soils.

Book excerpt: Soil is an irreplaceable resource that sustains life on the planet, challenged by food and energy demands of an increasing population. Therefore, soil contamination constitutes a critical issue to be addressed if we are to secure the life quality of present and future generations. Integrated efforts from researchers and policy makers are required to develop sound risk assessment procedures, remediation strategies and sustainable soil management policies. Environmental Risk Assessment of Soil Contamination provides a wide depiction of current research in soil contamination and risk assessment, encompassing reviews and case studies on soil pollution by heavy metals and organic pollutants. The book introduces several innovative approaches for soil remediation and risk assessment, including advances in phytoremediation and implementation of metabolomics in soil sciences.

Download or read book Evaluation of Novel Soil Amendments in Reducing Heavy Metal and Emerging Organic Contaminant Pollution from Wastewater Irrigation in Soil plant Systems written by Ali Mawof and published by . This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The world's rapidly growing food needs have led to a greater demand for freshwater for irrigated agricultural production. In many developing countries, farmers facing water scarcity resort to partially-treated or untreated wastewater for irrigation; however, these countries' wastewater treatment plants seldom have the technology to efficiently remove conventional and emerging contaminants, from wastewater. Given the risk they pose to human, animal and aquatic life, and the critical need to develop cost-effective, user-friendly techniques to lower the risk posed by these contaminants, an understanding of how they accumulate in soil, crops and in ground- or surface waters, achieved through the monitoring of their fate in the environment, is key to successfully mitigating their adverse effects. Biochar (BC) and compost (CP) soil amendments can immobilize several heavy metals and organic contaminants in soil and thereby reduce their uptake by plants. While the presence of nanoparticles (NPs) have shown promise in reducing the uptake of contaminants in plants; however, given the paucity of soil-plant system studies investigating the effects of NPs delivered to the soil via irrigation, the potential effects of NPs on soil-crop systems are poorly understood. Accordingly, a two-year field lysimeter study (2017-2018), laid out in a thrice-replicated randomized design was implemented to investigate: (i) the effects of soil amendments of barley straw biochar and green table waste compost, applied alone or in combination, and (ii) the effects of TiO2 nanoparticles (TiO2-NPs) delivered in wastewater, on the transport within the soil of wastewater-irrigation-delivered coexisting inorganic and organic contaminants, and their uptake by a crop (potatoes). The biochar/compost soil amendment treatments were: (i) non-amended soil (ii) 1% BC; (iii) 3% BC; (iv) 7.5% CP alone; (v) 1% BC and 7.5% CP; (vi) 3% BC and 7.5% CP. Treatments in the irrigation-water-delivered TiO2-NPs experiment, included: (i) synthetic wastewater (WW) (ii) freshwater (FW), and (iii) wastewater bearing TiO2-NPs. Treatments impacts on soil properties, along with contaminant mobility and uptake by potato plants were monitored. Alone or mixed with biochar, compost provided a more effective reduction in the uptake of Cd, Cu and Zn into plants and in retaining heavy metals in the topsoil, than did other treatments. Similar effects for these metals were observed under the TiO2-NPs (vs. WW control). A biochar (vs. compost) amendment showed a greater (p £ 0.05) effect on mobility of PPCPs. Crop Cr, Fe, and Pb uptake remained unaffected by any treatment. The effects of soil biochar/compost amendment on potato growth and yield assessed at maturity varied over the two seasons: (i) potato yield was significantly lower (p £ 0.05) after the warmer 2018 growing season than in 2017, (ii) in 2018, unlike 2017, the 3% BC treatment provided a greater yield than other treatments, likely attributable to biochar's greater (p £ 0.05) stability in soil into a second season, (iii) soil amendments had no significant effect on plant health parameters. Overall, biochar and compost (alone and mixed) reduced plant uptake of certain heavy metals and organic contaminants' mobility by improving soil properties, thereby facilitating immobilization. This suggests that soil amendments and the presence of NPs in wastewater can contribute to the safe use of wastewater for irrigation"--
