Emerging Contaminants
Emerging Contaminants presents the reader with information on classification, recent studies, and adverse effects on the environment and human health of the main classes of contaminants. Emerging contaminants are synthetic or natural compounds and microorganisms produced and used by humans that cause adverse ecological and human health effects when they reach the environment. This book is organized into four sections that cover the classification of contaminants and the instrumental techniques used to quantify them, recent studies on pesticides, antibiotics as an important group of emerging contaminants, and studies of different classes of emerging contaminants such as polybrominated diphenyl ethers (PBDEs), microplastics, and others.
Analysis of Exogenous Poisoning by Pesticide in the State of Bahia-Brazil During the Period from 2007 to 2017
Brazil is one of the main exporters of agricultural products and is one of the largest consumers of pesticides in the world. Bahia stands out in irrigated agriculture, with growth at the national and international level exports. The aim of this study is to describe and analyze the spatial distribution, and the epidemiological profile of the population with confirmed cases of pesticides intoxication in the state of Bahia-Brazil, from 2007 to 2017. It is an ecological and retrospective study of a series, with secondary data collected at the Department of Informatics of the System Of Health (DATASUS), on notifications and confirmed cases of pesticide poisoning in the state in 2007 to 2017. In B...
Cholinergic Mechanisms
Providing a cutting-edge profile of research progress in this important field of study, Cholinergic Mechanisms: Function and Dysfunction contains a compilation of the proceedings of the Eleventh ISCM, held in St. Moritz, May 2002. Bringing together 250 contributors from 30 countries, the book presents a comprehensive picture of the cholinergic field. It provides a survey of current understanding of molecular, pharmacological, toxicological, behavioral, and clinical aspects of the cholinergic system. This volume offers a state-of-the-art account of progress in the field from the molecule in the test tube through the cell and the synapse, to the organism and the patient.
Biochemistry and Molecular Biology of Parasites
The study of parasitic organisms at the molecular level has yielded fascinating new insights of great medical, social, and economical importance, and has pointed the way for the treatment and prevention of the diseases they cause. Biochemistry and Molecular Biology of Parasites presents an up-to-date account of this modern scientific discipline in a manner that allows and encourages the reader to place the biochemistry and molecular biology of these organisms in their biological context. The chapters are cross-referenced and grouped in an arrangement that provides a fully integrated whole, and permits the reader to create a composite of the biochemical function of these organisms.Individual ...
Biosorption
Municipal and industrial wastewaters contain a wide spectrum of pollutants. Their effective removal presents a challenge for water treatment technology. Biosorption of nutrients and pollutants has been used in sewage treatment since the discovery of the activated sludge process. It is a passive uptake process by which pollutants are adsorbed on the surface of cell walls and/or dissolved in structures of microorganism cells that are present in sludge. Sorbed pollutants remain in the sludge and can be potentially released back into the environment depending on their condition and the reversibility of the pollutant-sludge interaction. An overview of typical biosorption applications for the removal of nutrients, organic pollutants, and metals in wastewater treatment is provided in different areas of their use for the protection of aquatic ecosystems and human health. This book will be of interest to operators of wastewater treatment plants and sludge treatment and disposal facilities as well as to researchers and university students in the field of environmental engineering.
Abiotic Stress in Plants
World population is growing at an alarming rate and is anticipated to reach about six billion by the end of year 2050. On the other hand, agricultural productivity is not increasing at a required rate to keep up with the food demand. The reasons for this are water shortages, depleting soil fertility and mainly various abiotic stresses. The fast pace at which developments and novel findings that are recently taking place in the cutting edge areas of molecular biology and basic genetics, have reinforced and augmented the efficiency of science outputs in dealing with plant abiotic stresses. In depth understanding of the stresses and their effects on plants is of paramount importance to evolve effective strategies to counter them. This book is broadly dived into sections on the stresses, their mechanisms and tolerance, genetics and adaptation, and focuses on the mechanic aspects in addition to touching some adaptation features. The chief objective of the book hence is to deliver state of the art information for comprehending the nature of abiotic stress in plants. We attempted here to present a judicious mixture of outlooks in order to interest workers in all areas of plant sciences.
Water Chemistry
Water, which plays an important role in every aspect of our daily lives, is the most valuable natural resource we have on this planet. Drinking, bathing, cooking, regeneration, cleaning, production, energy, and many other uses of water originate from some of its versatile, useful, basic, and unique features. The access, purification, and reuse of water on our planet, which is of course not endless and not available for direct use, is directly related to the water chemistry that explores its inimitable properties. This book includes research on water chemistry-related applications in environmental management and sustainable environmental issues such as water and wastewater treatment, water quality management, and other similar topics. The book consists of three sections, namely, water treatment, wastewater treatment, and water splitting, respectively, and includes 11 chapters. In these chapters, water-wastewater remediation methods, nanomaterials in water treatment, and water splitting processes are comprehensively reviewed in terms of water chemistry.The editors would like to record their sincere thanks to the authors for their contributions.
Water Quality
Water Quality – Science, Assessments and Policy examines many of the scientific issues; national, regional and local assessment practices and results; and national policy issues related to water quality. Chapters focus on three areas: water quality parameters, water quality treatments, and water quality assessments. This book provides a basic understanding of water quality issues and practical examples of their solution.
Fish Nutrition
Fish Nutrition, Fourth Edition is an up-to-date, authoritative presentation of all key elements of the nutrition of fish and crustaceans. As aquaculture is rapidly expanding, more than 200 herbivorous and carnivorous species occupy a diverse range of ecological niches, and have therefore evolved to utilize a wide array of food sources. This new edition highlights these differences and covers the complexity and challenges associated with fish nutrition, addressing nutrient requirements to produce high-quality, healthful and sustainable resources, the essential nutrients for fish species, including proteins and amino acids, vitamins, minerals and essential fatty acids, a feed quality assessmen...
