Tools Techniques And Protocols For Monitoring Environmental Contaminants

Tools, Techniques and Protocols for Monitoring Environmental Contaminants describes information on the strategic integration of available monitoring methods with molecular techniques, with a focus on omics (DNA, RNA and protein based) and molecular imprinted polymer and nanomaterial based advanced biosensors for environmental applications. It discusses the most commonly practiced analytic techniques, such as HPLC, MS, GCMS and traditional biosensors, giving an overview of the benefits of advanced biosensors over commonly practiced methods in the rapid and reliable assessment of environmental contaminants. As environmental contaminants have become one of the serious concerns in terms of their rapid growth and monitoring in the environment, which is often limited due to costly and laborious methods, this book provides a comprehensive update on their removal, the challenges they create for environmental regulatory agencies, and their diverse effects on terrestrial and aquatic environments. Provides methods for assessing and monitoring environmental contaminants Includes recent advancement in molecular techniques Outlines rapid environmental monitoring methods Explains the use of biosensors for environmental monitoring Reviews monitoring methods beyond conventional analytic techniques

Monitoring pollutants in air, soil and water is a routine requirement in the workplace, and in the wider environment. Passive samplers can provide a representative picture of levels of pollutants over a period of time from days to months by measuring the average concentrations to which they have been exposed. Air monitors are widely used, for instance to measure the exposure of workers to volatile compounds, but also for monitoring the fate of pollutants in the atmosphere. Passive sampling devices are now becomining increasingly used to monitor pollutants in rivers, coastal waters and ground water where contamination results from sources such as domestic and industrial discharges, and the use of agrochemicals. Passive Sampling Techniques in Environmental Monitoring provides a timely collection of information on a set of techniques that help monitor the quality of air, surface and ground waters. Passive sampling can provide an inexpensive means of obtaining a representative picture of quality over a period of time, even where levels of pollutants fluctuate due to discontinuous discharges or seasonal application of chemicals such as pesticides. Recent changes in legislation have increased the pressure to obtain better information than that provided by classical infrequent spot sampling.Brought together in one source, this book looks at the performance of a range of devices for the passive sampling of metals, and of non-polar and polar organic chemicals in air and in water. The strengths and weaknesses and the range of applicability of the technology are considered. * Comprehensive review of passive sampling - covering air, water and majority of available technologies in one volume* Chapters written by international specialist experts * Covers theory and applications, providing background information and guidelines for use in the field

Techniques being developed to purify, fractionate, and classify complex organic chemical residues will simplify the detection of these residues and provide more comprehensive data about them. These techniques include an integrated series of chromatographic processes, new technology in mass spectrometry, advances in glass capillarygas chromatography, and chemical derivatization.

The contamination of environment and water resources by Selenium (Se) and its oxyanions from various sources are emerging contaminants of significant health and environmental concern. The primary sources include agricultural drainage water, mine drainage, residues from fossil fuels, thermoelectric power plants, oil refineries, and metal ores. Various methods and technologies have been developed which focus on the treatment of selenium-containing waters and wastewater. High concentrations of selenium in water cause various adverse impact to human health, such as carcinogenic, genotoxic, and cytotoxic effects. But in the lower concentrations, it is a useful constituent of the biological system. The range between toxicity and deficiency of selenium is minimal (40 to 400 μg per day), due to its dual nature. Selenium Contamination in Water contains the latest status and information on selenium’s origin, its chemistry and its toxicity to humans. The book represents a comprehensive and advanced reference book for students, researchers, practitioners, and policymakers in working in the field of metalloids, in particular selenium. A special emphasis is given on its geological distribution, monitoring techniques, and remedial technologies. As such, the authors critically analyze the various techniques used for the monitoring and removal of selenium from water. Featuring chapters arranged according to the major themes of the latest research, with specific case-studies from industrial experiences of selenium detection and removal, Selenium Contamination in Water will be particularly valued by researchers, practitioners, and policymakers in working in the field of metalloids including selenium.
