This book was released on 2014 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acid mine drainage (AMD) with low pH and high levels of heavy metals affects many regions. Experiments were conducted to investigate the bioremediation potential of AMD contaminated soils via Phragmites australis, rhizosphere acidophilic heterotrophs and/or Fe(II) oxidizing bacteria (Fe(II)OB), and citric acid (CA). Field characterizations indicated that Fe plaque amounts on reeds were related to the abundance of Fe(II)OB in soil. The metal concentrations in roots of reeds also depicted a strong correlation with the soil concentrations. The Fe concentrations in soil were 413.63 [plus or minus] 7.75 mg/g which were much higher than Mn (0.04 [plus or minus] 0.00 mg/g) and Al (1.39 [plus or minus] 0.03 mg/g), while the Fe amounts in roots (13.43 [plus or minus] 5.98 mg/g) were also higher than Mn (0.09 [plus or minus] 0.03 mg/g) and Al (0.08 [plus or minus] 0.01 mg/g). Histological staining found that most of Fe and Al were stored in exodermis and endodermis of roots. Laboratory experiments indicated that Fe(II)OB enhanced the formation of Fe plaque. The root Fe plaque (108.08 [plus or minus] 12.05 mg/g) of reeds cultured in spiked soil inoculated with Fe(II)OB were higher than that without adding Fe(II)OB (88.47 [plus or minus] 5.26 mg/g). CA inhibited the formation of Fe plaque. However, acidophilic heterotrophs consumed CA and enhanced the growth of Fe(II)OB. Metal plaque may decrease the accumulation of Fe and Mn into reeds while had no important influence on Al uptake. CA enhanced Fe and Al entering stele of roots and increased metals uptake in reeds. Compared with non-contaminated reeds, wild reeds initially grown in AMD sites accumulated more metals due to the adaptability to the hostile environments. For instance, wild reeds cultured in soil added with 33.616 g/kg CA accumulated 0.32 [plus or minus] 0.01 mg/g Mn, 96.99 [plus or minus] 5.75 mg/g Fe and 3.17 [plus or minus] 0.51 Al in roots, while purchased reeds uptake 0.20 [plus or minus] 0.00 mg/g Mn, 79.21 [plus or minus] 5.95 mg/g Fe and 0.74 [plus or minus] 0.02 Al mg/g. CA, rhizosphere bacteria and reeds had interconnected impacts on remediation of AMD sites. CA significantly enhanced phytoremediation efficiency. Rhizosphere microorganisms also influenced metal bioavailability and metal uptake in reeds. Wild reeds in spiked soil or solution amended with 33.616 g/kg CA and without bacteria uptake the most metals. Further investigations are required to study the effect of CA and rhizosphere bacteria on phytoremediation of real AMD contaminated field.

Available in PDF, EPUB and Kindle. Book excerpt: The pollution of soil and groundwater by harmful chemical compounds and heavy metals is becoming very serious in many countries. Although remediation is necessary as soon as possible, the performance of conventional bioremediation processes is not sufficient. This book deals with advances in bioremediation and phytoremediation processes by using excellent strains and a combination of processes. In the chapters of this book, the researchers have introduced the overall status of contamination; the characteristics of bioremediation using halobacteria, Candida yeast, and autochthonous bacteria; and phytoremediation using macrophytes. Moreover, other researchers introduced a process using biochar and electric currents, and this combination of processes and phytoremediation enhances the overall process.
Download or read book Assessment of Bioremediation Efficiency of Indigenous Bacteria and Plants at an Abandoned Acid Mine Drainage Site written by Sushil Sivaram and published by . This book was released on 2010 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollution caused by acid mine drainage is a widespread problem throughout the world. Biological means to remediate the damage caused by AMD is the most effective and economical treatment procedure. Due to the long treatment duration efforts to remediate lands using this technique has not been explored a lot. This research examines the various biological means to establish a treatment scheme for an acid mine affected area in Northeast Ohio. The various plausible schemes included phytoremediation using plants found onsite - Phragmites, Cattail, Goldenrod and Soybean and the possibility of microbial remediation. A site characterization was done which examined the microbial numbers across the transect and at various depth over three different seasons and a kinetic rate model was established to help predict the behavior of the microorganisms present in the soil at varying conditions. The number of iron oxidizers was found to be greater in areas with lesser toxic metals (average iron oxidizers at the three sites closest to the emergence point was 1.15E+05 CFU/g, corresponding average count for heterotrophic microorganisms was 8.16E+04 CFU/g. Heterotrophic microorganisms were found in greater numbers further away from the emergence point than iron oxidizers (average of the three points farthest from the emergence point over second and third sample 1.04E+06 CFU/g). Microbial numbers were correlated to iron oxidation rates. The rates were found to be higher at points with higher number of iron oxidizers. Seasonal variation in microbial numbers indicated an overall decrease in numbers during the winter (average iron oxidizers winter sample 2.93E+04 CFU/g, average iron oxidizers for summer sample 6.33E+05 CFU/g). Phragmites and Cattail were found to hyperaccumulate Al from the soil. Phragmites was also able to uptake substantial amounts of Fe (shoot concentration of 6.74 mg). The contributions made by the other species of plants to accumulate various metals were also notable. The higher biomass and overall capacity of Phragmites to uptake various metals make it an ideal choice if phytoremediation is employed on site. Microbial remediation was found to be currently occurring at a slow pace on the site. Even though the rate of remediation was found to be slow, the presence of remedial actions by the plants and microbes on site, without any intervention, shows that bioremediation potential of the site.

Download or read book Phytoremediation of Contaminated Soil and Water written by Norman Terry and published by CRC Press. This book was released on 2020-11-25 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phytoremediation is an exciting, new technology that utilizes metal-accumulating plants to rid soil of heavy metal and radionuclides. Hyperaccumulation plants are an appealing and economical alternative to current methods of soil recovery. Phytoremediation of Contaminated Soil and Water is the most thorough literary examination of the subject available today. The successful implementation of phytoremediation depends on identifying plant material that is well adapted to specific toxic sites. Gentle remediation is then applied in situ, or at the contamination site. No soil excavation or transport is necessary. This severely contains the potential risk of the pollutants entering the food chain. And it's cost effective. The progress of modern man has created many sites contaminated with heavy metals. The effected land is toxic to plants and animals , which creates considerable public interest in remediation. But the commonly used remedies are ex situ, which poses an expensive dilemma and an even greater threat. Phytoremediation offers the prospect of a cheaper and healthier way to deal with this problem. Read Phytoremediation of Contaminated Soil and Water to learn just how far this burgeoning technology has developed.
