Understand the Environmental Processes That Control Groundwater Quality
The integration of environmental isotopes with geochemical studies is now recognized as a routine approach to solving problems of natural and contaminated groundwater quality. Advanced sampling and analytical methods are readily accessible and affordable, providing abundant geochemical and isotope data for high spatial resolution and high frequency time series. Groundwater Geochemistry and Isotopes provides the theoretical understanding and interpretive methods and contains a useful chapter presenting the basics of sampling and analysis.
This text teaches the thermodynamic basis and principal reactions involving the major ions, gases and isotopes during groundwater recharge, weathering and redox evolution. Subsequent chapters apply these principles in hands-on training for dating young groundwaters with tritium and helium and ancient systems with radiocarbon, radiohalides and noble gases, and for tracing reactions of the major contaminants of concern in groundwaters.
Covers the basics of solutes, gases and isotopes in water, and concentration-activity relationships and reactions
Describes tracing the water cycle, weathering, and the geochemical evolution of water quality
Explores dating groundwater as young as a few years to over hundreds of millions of years
Uses case studies to demonstrate the application of geochemistry and isotopes for contaminated groundwaters
Accessible to consultants and practitioners as well as undergraduates, Groundwater Geochemistry and Isotopes presents the basics of environmental isotopes and geochemistry, and provides you with a full understanding of their use in natural and contaminated groundwater.

Edited by One of the Best Specialists in Soil Science
Recent studies reveal that Phosphorus (P) in the form of phosphate, a macronutrient essential for plant growth, and crop yields can influence the bioavailability, retention, and mobility of trace elements, metal(loid)s, and radio nuclides in soils. When this occurs, phosphates can affect the dynamics of heavy metals and influence soil characteristics, impacting soil mobility and toxicity.
Phosphate in Soils: Interaction with Micronutrients, Radionuclides and Heavy Metals
utilizes the latest research to emphasize the role that phosphate plays in enhancing or reducing the mobility of heavy metals in soil, and the soil-water-plant environment. It provides an in-depth understanding of each heavy metal species, and expands on phosphate interactions in geological material.
Composed of 12 chapters, this text:
Provides an overview of the reactions of metal(loid)s and common P compounds that are used as fertilizer in soils
Emphasizes the effect of phosphorus on copper and zinc adsorption in acid soils
Discusses findings on the influence of phosphate compounds on speciation, mobility, and bioavailability of heavy metals in soils as well as the role of phosphates on in situ and phytoremediation of heavy metals for contaminated soils
Places emphasis on the influence of phosphate on various heavy metals species in soils, and their solubility/mobility and availability
Provides extensive information on testing various high phosphate materials for remediation of heavy metal, micronutrients, and radionuclides contaminated sites
Explores the reactivity of heavy metals, micronutrients and radionuclides elements in several soils
Presents a case study illustrating various remediation efforts of acidic soils and remediation of Cu, Zn, and lead (Pb) contaminated soils around nonferrous industrial plants
Emphasizes the significance of common ions (cations and anions) on phosphate mobility and sorption in soils, and more
The author includes analytical and numerical solutions along with hands-on applications, and addresses other topics that include the transport and sorption modeling of heavy metals in the presence of phosphate at different scales in the vadose zone.

Описание: This book provides a comprehensive description of phosphate solubilizing microorganisms and highlights methods for the use of microphos in different crop production systems. The focus is on understanding both the basic and applied aspects of phosphate solubilizing microorganisms and how phosphorus-deficient soils can be transformed into phosphorus-rich ones by applying phosphate solubilizing microorganisms. The interaction of rhizosphere phosphate solubilizing microorganisms and environmental variables, as well as their importance in the production of crops such as legumes, cereals, vegetables etc. are discussed and considered. The use of cold-tolerant phosphate solubilizing microorganisms to enhance crop productivity in mountainous regions is examined, as are the ecological diversity and biotechnological implications of phosphate solubilizing microorganisms. Lastly, the role of phosphate solubilizing microorganisms in aerobic rice cultivation is highlighted. This volume offers a broad overview of plant disease management using phosphate solubilizing microbes and presents strategies for the management of cultivated crops. It will therefore be of special interest to both academics and professionals working in the fields of microbiology, soil microbiology, biotechnology and agronomy, as well as the plant protection sciences. This timely reference book provides an essential and comprehensive source of material, as it includes recent findings on phosphate solubilizing microorganisms and their role in crop production.

Описание: Vanadium isotope ratios (51V/50V) have potential to provide information about changes in past ocean oxygen contents. The oxygen abundance sensitivity range of V isotopes suggests that this paleoproxy could be particularly useful in tracing marine oxygenation changes throughout the Phanerozoic and potentially beyond.
