The Global Arsenic Problem
A prevalent and increasingly important issue, arsenic removal continues to be one of the most important areas of water treatment. Conventional treatment plants may employ several methods for removing arsenic from water. Commonly used processes include oxidation, sedimentation, coagulation and filtration, lime treatment, adsorption onto sorptiv
Advances in Subsurface Pollution of Porous Media - Indicators, Processes and Modelling
Advances in Subsurface Contamination of Porous Media: Indicators, Processes and Modelling provides a high level understanding of the processes concerning common and emergent contaminants through their passage from soil to groundwater. The book presents new methodologies and indicators to reach a better understanding of biogeochemical processes as a basis for environmental models. The combined use of the understanding of processes and models’ prognosis will inform researches and water managers and will provide the possibility for better management and preservation of water resources. The book will be a valuable reference for graduate students, researchers and professionals in government and public institutions, and for those interested in soil and groundwater contamination in various aspects.
Arsenic in Drinking Water and Food
Arsenic contamination poses a major environmental problem, especially in Southeast Asian countries like Bangladesh and India. Threatening the health of millions of people due to arsenic’s toxicity and carcinogenicity, the major routes of arsenic exposure for humans are either through drinking water or crops. Rice is the crop most affected by arsenic owing to its cultivation in major arsenic contaminated areas, biogeochemical factors in the soil during rice growth, and specific features of rice that enable it take up more arsenic than other crop plants. This book addresses the problem of arsenic by pursuing a holistic approach. It presents the status quo in different parts of the world (Nor...
Advances in In Situ Biological and Chemical Groundwater Treatment
This book collects the peer-reviewed contributions accepted for the publication in the Special Issue “Advances in In Situ Biological and Chemical Groundwater Treatment” of the MDPI journal Water. As such, the contributions refer to a variety of widespread pollutants (chlorinated ethenes, chlorinated phenols, chromium, copper, nickel, and arsenic phenols) and new remediation approaches (bioremediation, bioelectrochemical systems, and sorption), covering lab and field studies.
Medical Geology
Medical Geology The key to understanding the relationship between the geological environment and human health Medical geology deals with of the impact of environmental factors on the health of individual human beings and communities. In particular, it studies environmental exposure to both macro- and micronutrients in the geosphere, hydrosphere, and atmosphere—respectively, soil, water, and airborne dust—which may positively or negatively impact human growth, development, and overall health. The insights contributed by this burgeoning field can aid not only in individual medical cases, but also in assessing disproportionately impacted communities and addressing global medical inequality....
Advanced Oxidation Technologies
Advanced Oxidation Technologies (AOTs) or Processes (AOPs) are relatively new and innovative technologies to remove harmful and toxic pollutants. The most important processes among them are those using light, such as UVC/H2O2, photo-Fenton and heterogeneous photocatalysis with TiO2. These technologies are also relatively low-cost and therefore useful for countries under development, where the economical resources are scarcer than in developed countries. This book provides a state-of-the-art overview on environmental applications of Advanced Oxidation Technologies (AOTs) as sustainable, low-cost and low-energy consuming treatments for water, air, and soil. It includes information on innovativ...
Advances in Drinking Water Purification
Advances in Drinking Water Purification: Small Systems and Emerging Issues captures the knowledge and impact on the performance of various types of water purification technologies and identities the need for further development with a view to carry forward the SDG global targets of achieving safe and affordable drinking water. The book bridges the knowledge gap between various types of treatability options which is essential for selection of suitable treatment systems and augmentation in the desirable levels of specific contaminants. It focuses on providing the scope of selecting location specific technology options by presenting multiple approaches for treatment of most crucial toxic contam...
Arsenic Contamination in the World
Arsenic Contamination in the World: an International Sourcebook provides a global compendium of cited arsenic occurrences in the world as they affect public health. This book details arsenic contamination by source, region and arsenic-affected country. Arsenic is identified in 105 countries and territories, representing a larger database than any previous published work. Sources of arsenic contamination are categorized as Anthropogenic, Geogenic, Volcanogenic, Coal, Mining and Petroleum-related. National, regional and international maps locate the affected areas and populations. A synthesis of critical country information includes an estimate of the exposed population of 226 million people w...
Geological and Geo-Environmental Processes on Earth
This edited volume dedicated to late Prof. P.S. Saklani addresses the multidisciplinary themes pertaining to role of tectonism and magmatism in Crustal Evolution and global distribution of metallic and non metallic mineral deposits. It gives valuable information on geodynamic evolution, structural, petrological, isotopic, metamorphic, geochemical and geochronological attributes of continental and oceanic crust and is challenging reassessments of the existing paradigms. It addresses the implication of magmatism, metallogeny and application of geochronological ages (U-Pb SHRIMP age, Lu-Hf isotopic system; detrital zircons). This book also advocates the role of tectonics in contamination of gro...
