Book Synopsis Biogeochemistry of Trace Elements in the Rhizosphere by : G.R. Gobran
Download or read book Biogeochemistry of Trace Elements in the Rhizosphere written by G.R. Gobran and published by Elsevier. This book was released on 2011-08-11 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rhizosphere in soil environments refers to the narrow zone of soil influenced by the root and exudates. Microbial populations in the rhizosphere can be 10 - 100 times larger than the populations in the bulk soil. Therefore, the rhizosphere is bathed in root exudates and microbial metabolites and the chemistry and biology at the soil-root interface is governed by biotic (plant roots, microbes) and abiotic (physical and chemical) interactions. The research on biotic and abiotic interactions in the rhizosphere should, thus, be an issue of intense interest for years to come. This book, which consists of 15 chapters, addresses a variety of issues on fundamentals of microscopic levels and the impact on food chain contamination and the terrestrial ecosystem. It is an essential reference work for chemists and biologists studying environmental systems, as well as earth, soil and environmental scientists.* 15 chapter book, which addresses a variety of issues on fundamentals of microscopic levels and the impact on food chain contamination and the terrestrial ecosystem

Advances in research methodology, the use of synchrotron radiation in particular, are extensively reviewed. Roles of microbes, biomolecules, and environmental nanoparticles in mineral transformations, metal cycling, degradation of natural and anthropogenic organic compounds are also extensively reviewed. It is unique in terms of facilitating the integration of contributions from traditionally separate disciplines and adding a molecular and nanoparticle (therefore chemical) dimension to a field of endeavour that has traditionally been viewed on a different scale (dimension). It will also contribute to identifying knowledge gaps, providing future research directions and promoting research and education at the molecular level in this extremely important and challenging area of science for years to come. The IUPAC Project Committee noted that the Conference identifies, and builds on, the need to view and understand the Critical Zone at the molecular level. The book will be an invaluable reference for research and education.

Contributors include those currently working for the European research programme, COST Action 639 BurnOut (www.cost639.net; 2006-2010). COST Action 639 emerged from a demand from policy makers in Europe for more detailed information on soil carbon dynamics. The cooperation between experts for reporting and experts for soil dynamics is the focus of the book. This book seeks to provide an up-to-date account on the state-of-the-art research within this topical field.
Book Synopsis Chlorine Cycling in Terrestrial Environments by : Malin Montelius
Download or read book Chlorine Cycling in Terrestrial Environments written by Malin Montelius and published by Linköping University Electronic Press. This book was released on 2016-03-08 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chlorinated organic compounds (Clorg) are produced naturally in soil. Formation and degradation of Clorg affect the chlorine (Cl) cycling in terrestrial environments and chlorine can be retained or released from soil. Cl is known to have the same behaviour as radioactive chlorine-36 (36Cl), a long-lived radioisotope with a half-life of 300,000 years. 36Cl attracts interest because of its presence in radioactive waste, making 36Cl a potential risk for humans and animals due to possible biological uptake. This thesis studies the distribution and cycling of chloride (Cl–) and Clorg in terrestrial environments by using laboratory controlled soil incubation studies and a forest field study. The results show higher amounts of Cl– and Clorg and higher chlorination rates in coniferous forest soils than in pasture and agricultural soils. Tree species is the most important factor regulating Cl– and Clorg levels, whereas geographical location, atmospheric deposition, and soil type are less important. The root zone was the most active site of the chlorination process. Moreover, this thesis confirms that bulk Clorg dechlorination rates are similar to, or higher than, chlorination rates and that there are at least two major Clorg pools, one being dechlorinated quickly and one remarkably slower. While chlorination rates were negatively influenced by nitrogen additions, dechlorination rates, seem unaffected by nitrogen. The results implicate that Cl cycling is highly active in soils and Cl– and Clorg levels result from a dynamic equilibrium between chlorination and dechlorination. Influence of tree species and the rapid and slow cycling of some Cl pools, are critical to consider in studies of Cl in terrestrial environments. This information can be used to better understand Cl in risk-assessment modelling including inorganic and organic 36Cl. Klorerade organiska föreningar (Clorg) bildas naturligt i mark och påverkar klorets kretslopp genom att de stannar kvar längre i marken. Detta stabila klor anses ha samma egenskaper som klor-36, som är en långlivad radioisotop med en halveringstid på 300 000 år. Klor-36 förekommer i olika typer av radioaktivt avfall och om klor-36 sprids i naturen finns det en potentiell risk för människor och djur genom biologiskt upptag. Syftet i denna avhandling är att öka kunskapen om fördelningen och cirkulationen av klorid (Cl-) och Clorg i terrestra miljöer med hjälp av studier i laboratoriemiljö samt en fältstudie i skogsmiljö. Resultaten visar att bildningshastigheten av Clorg är högst i barrskogsjord och rotzonen tycks vara en aktiv plats. Det finns också en större mängd Cl- och Clorg i barrskogsjordar än i betesmark och jordbruksmark. Den mest betydande faktorn som styr halterna av Cl- och Clorg är trädsort, medan geografiskt läge, atmosfäriskt nedfall, och jordmån är av mindre betydelse. Bildning och nedbrytning av Clorg sker med liknande hastigheter, men det tycks finnas två förråd av Clorg i jorden varav ett bryts ner snabbt och ett mer långsamt. Bildningshastigheten av Clorg är lägre i jordar med höga halter av kväve medan nedbrytningshastigheterna inte påverkas av kväve. Slutsatsen från studiernas resultat är att klor i hög grad är aktivt i mark och att Cl- och Clorg halterna bestäms av en dynamisk jämvikt mellan bildning och nedbrytning av Clorg. I studier av klor i terrestra miljöer bör trädsorters inverkan och nedbrytning av olika klorförråd beaktas då det kan ge varierande uppehållstider av Cl- och Clorg i mark. Denna information är viktig vid riskbedömningar av hur radioaktivt klor kan spridas och cirkulera vid en eventuell kärnkraftsolycka.

Book Synopsis Microbial Bioremediation & Biodegradation by : Maulin P. Shah
Download or read book Microbial Bioremediation & Biodegradation written by Maulin P. Shah and published by Springer Nature. This book was released on 2020-04-30 with total page 547 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial or biological degradation has long been the subject of active concern, and the rapid expansion and growing sophistication of various industries in the last century has significantly increased the volume and complexity of toxic residues of wastes. These can be remediated by plants and microbes, either natural origin or adapted for a specific purpose, in a process known as bioremediation. The interest in microbial biodegradation of pollutants has intensified in recent years in an attempt to find sustainable ways to clean contaminated environments. These bioremediation and biotransformation methods take advantage of the tremendous microbial catabolic diversity to degrade, transform or accumulate a variety of compounds, such as hydrocarbons, polychlorinated biphenyls, polaromatic hydrocarbons pharmaceutical substances, radionuclides and metals. Unlike conventional methods, bioremediation does not physically disturb the site. This book describes the basic principles of biodegradation and shows how these principles are related to bioremediation. Authored by leading, international environmental microbiologists, it discusses topics such as aerobic biodegradation, microbial degradation of pollutants, and microbial community dynamics. It provides valuable insights into how biodegration processes work and can be utilised for pollution abatement, and as such appeals to researchers and postgraduate students as well as experts in the field of bioremediation.
