Book Description
Biological and Environmental Aspects of Chromium focuses on the biological and environmental aspects of chromium and its compounds, with emphasis on the most important aspects of their toxicology and physiology. Topics covered range from the production and occupational exposure of chromium compounds to the presence of chromium in air, soil, and natural waters. The applications of chromium in cell biology and medicine are also discussed. Comprised of 11 chapters, this volume begins with an overview of the toxic and carcinogenic effects of chromium and chromium compounds, followed by a discussion on the production and occupational exposure of chromium compounds. The reader is then introduced to the more common analytical methods used in the determination of chromium in environmental and biological samples. Subsequent chapters explore the nutritional role of chromium; absorption, transport, and excretion of chromium in humans and animals; mutagenic and cytogenetic effects of chromium compounds; and organ toxicity of chromium in animals. The carcinogenic effects of chromium, including its effects on the skin, are also considered. This monograph will be of interest to students, practitioners, and researchers in the fields of biology, physiology, and chemistry, as well as those with an objective interest in the ways in which chromium and its compounds act in biological materials and in the human environment.

Book Description
This edited book brings together a diverse group of environmental science, sustainability, and health researchers to address the challenges posed by global mass poisoning caused by chromium contamination of soil and plants. In recent years, contamination of the environment by chromium has become a major concern. Chromium is a non-degradable, harmful, and toxic pollutant which negatively affects the environment. It is unique among the heavy metals found in industrial wastewater and sewage and sludge, as it may exist as a trivalent cation and as anion in the hexavalent state in the pH range of agricultural soils. It is used on a large scale in many different industries, including metallurgy, electroplating, production of paints and pigments, tanning, wood preservation, chemical production, and pulp and paper production. These industries are contributing larger amount of chromium, which can ultimately have significant adverse effects on biological and ecological activities of ecosystem. Chromium enters the food chain through consumption of plant material. A high concentration of chromium has been found to be harmful to vegetation. As the chromium concentration in plants increases, it adversely affects several biological parameters and eventually renders the soil barren. The book sheds light on this global environmental issue and proposes solutions to contamination through multi-disciplinary approaches and case studies from different parts of the world. This book is a valuable resource to students, academicians, researchers, and environmental professionals who are doing field work on chromium contamination throughout the world.

Book Description
Provides a comprehensive chemical and biochemical treatment on the effects of chromium in the environment and in man. Such an integrated treatment of the chemical and biochemical aspects of chromium is novel and has not appeared in the published literature. Reviews the information on global cycling and environmental occurrence of chromium compounds, which defines the extent of the environmental and toxicological concern. The treatment of chromium chemistry provides the basis for toxicological models of chromium hypersensitivity, mutagenicity, carcinogenicity, and toxicokinetics. Chapters contain graphical representations of the voluminous mutagenicity and animal carcinogenicity data according to chromium compound type, and a tabular summary of all published epidemiological data, broken down according to industry. Also covers clinical patterns, prognosis, pathogenesis, prophylaxis, and environmental and biological monitoring.

Book Description
This toxicological profile is prepared in accordance with guidelines developed by the Agency for Toxic Substances and Disease Registry (ATSDR) and the Environmental Protection Agency (EPA). The original guidelines were published in the Federal Register on April 17, 1987. Each profile will be revised and republished as necessary. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for the toxic substances each profile describes. Each peer-reviewed profile identifies and reviews the key literature that describes a substance's toxicologic properties. Other pertinent literature is also presented but is described in less detail than the key studies. The profile is not intended to be an exhaustive document; however, more comprehensive sources of specialty information are referenced. The profiles focus on health and toxicologic information; therefore, each toxicological profile begins with a public health statement that describes, in nontechnical language, a substance's relevant toxicological properties. Following the public health statement is information concerning levels of significant human exposure and, where known, significant health effects. A health effects summary describes the adequacy of information to determine a substance's health effects. ATSDR identifies data needs that are significant to protection of public health. Each profile: (A) Examines, summarizes, and interprets available toxicologic information and epidemiologic evaluations on a toxic substance to ascertain the levels of significant human exposure for the substance and the associated acute, subacute, and chronic health effects; (B) Determines whether adequate information on the health effects of each substance is available or being developed to determine levels of exposure that present a significant risk to human health of acute, subacute, and chronic health effects; and (C) Where appropriate, identifies toxicologic testing needed to identify the types or levels of exposure that may present significant risk of adverse health effects in humans.

Book Description
Environmental and Agricultural Microbiology Uniquely reveals the state-of-the-art microbial research/advances in the environment and agriculture fields Environmental and Agricultural Microbiology: Applications for Sustainability is divided into two parts which embody chapters on sustenance and life cycles of microorganisms in various environmental conditions, their dispersal, interactions with other inhabited communities, metabolite production, and reclamation. Though books pertaining to soil & agricultural microbiology/environmental biotechnology are available, there is a dearth of comprehensive literature on the behavior of microorganisms in the environmental and agricultural realm. Part 1 includes bioremediation of agrochemicals by microalgae, detoxification of chromium and other heavy metals by microbial biofilm, microbial biopolymer technology including polyhydroxyalkanoates (PHAs) and polyhydroxybutyrates (PHB), their production, degradability behaviors, and applications. Biosurfactants production and their commercial importance are also systematically represented in this part. Part 2 having 9 chapters, facilitates imperative ideas on approaches for sustainable agriculture through functional soil microbes, next-generation crop improvement strategies via rhizosphere microbiome, production and implementation of liquid biofertilizers, mitigation of methane from livestock, chitinases from microbes, extremozymes, an enzyme from extremophilic microorganism and their relevance in current biotechnology, lithobiontic communities, and their environmental importance, have all been comprehensively elaborated. In the era of sustainable energy production, biofuel and other bioenergy products play a key role, and their production from microbial sources are frontiers for researchers. The final chapter unveils the importance of microbes and their consortia for management of solid waste in amalgamation with biotechnology Audience The book will be read by environmental microbiologists, biotechnologists, chemical and agricultural engineers.
