Available in PDF, EPUB and Kindle. Book excerpt: Cyanobacteria, or blue-green algae, commonly occur in a variety of water types throughout the world. A variable, but, high proportion of the cyanobacterial blooms and scums, which can develop annually in lakes, reservoirs, canals and slow-flowing rivers, contain potent toxins. Although animal poisonings and human health problems associated with the ingestion of, or contact with, cyanobacterial scums have long been recognized, a developing understanding of the health hazards posed by the toxins requires that reliable, sensitive, specific and convenient methods are available for their detection and quantification.Detection methods for cynobacterial toxins looks at the application of biological, toxicological, biochemical and physicochemical techniques in studies of cyanobacterial toxins and at experimental methods that have identified at least 50 cyanobacterial compounds toxic to vertebrates.Academics, public health bodies, environmental protection agencies and water companies are all involved in monitoring cyanobacterial levels and effects, and this book will help to ensure that their research is not duplicated, is standardized and comparable, and that optimal progress can be made in an important area that is still in its developing stages.

Available in PDF, EPUB and Kindle. Book excerpt: "The analysis of contaminants of emerging concern is critical to protecting environmental health. In the presented dissertation, two groups of contaminants of emerging concern were assessed using mass spectrometry methods: nanoparticles and algal and cyanotoxins. Analysis of metal oxide nanoparticles in environmental matrices has been a challenging issue, as most traditional methods require complicated sample preparation methods or that can alter or destroy the nanoparticles in the system. Single particle inductively coupled plasma mass spectrometry (SP-ICP-MS) methods were used to detect metal oxide nanoparticles in surface waters and their removal through drinking water treatment simulations while retaining all information regarding primary particles. Methods were developed to monitor titanium dioxide, cerium dioxide, zinc oxide, citrate-coated silver, and citrated-coated gold nanoparticles directly in surface water and water treated by multiple drinking water treatment methods. Results from these studies indicate that removal depends on the starting water quality, the surface of the nanoparticles, and the type of treatment employed. Cyanotoxins, produced by freshwater cyanobacteria, are a group of contaminants of emerging concern at the freshwater-marine water continuum. Cyanotoxins and several marine algal toxins were analyzed by a direct injection liquid chromatography tandem mass spectrometry (LC/MS/MS) in estuary samples from the contiguous United States. Anatoxin-a, cylindrospermopsin, domoic acid, and microcystins were detected in U.S. estuaries, indicating that cyanotoxins are transported to or produced in estuary systems"--Abstract, page iv.

Download or read book Liquid Chromatography written by P. Otero and published by Elsevier Inc. Chapters. This book was released on 2013-01-08 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural toxins are an extremely complex group of compounds with high activity and diverse origin. The most important groups, in terms of human safety, are phycotoxins (produced by dinoflagellates), the parent freshwater compounds cyanobacterial toxins, and mycotoxins (produced by fungi). Many more toxins and bacterial and pluricellular organisms are known, such as equinoderms, sponges, and snails. Several technologies are available for the detection and quantification of natural toxins, including animal bioassays. This chapter focuses on the solutions most in demand, based on liquid chromatography with (mass) spectrometric detection for analysis of three groups of compounds with special difficulty: tetrodotoxin, lipophilic phycotoxins, and saxitoxins.

This book was released on 2017 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: A guide to state-of-the-art molecular tools for monitoring and managing the toxigenicity of cyanobacteria Runaway eutrophication and climate change has made the monitoring and management of toxigenic organisms in the world's bodies of water more urgent than ever. In order to influence public policy regarding the detection and quantification of those organisms, it is incumbent upon scientists to raise the awareness of policy makers concerning the increased occurrence of toxigenic cyanobacteria and the threats they pose. As molecular methods can handle many samples in short time and help identify toxigenic organisms, they are reliable, cost-effective tools available for tracking toxigenic cyanobacteria worldwide. This volume arms scientists with the tools they need to track toxigenicity in surface waters and food supplies and, hopefully, to develop new techniques for managing the spread of toxic cyanobacteria. This handbook offers the first comprehensive treatment of molecular tools for monitoring toxigenic cyanobacteria. Growing out of the findings of the landmark European Cooperation in Science and Technology Cyanobacteria project (CYANOCOST), it provides detailed, practical coverage of the full array of available molecular tools and protocols, from water sampling, nucleic acid extraction, and downstream analysis-including PCR and qPCR based methods-to genotyping (DGGE), diagnostic microarrays, and community characterization using next-gen sequencing techniques. -Offers an overview of the latest trends in the field, while providing a foundation for understanding and applying the tools and techniques described -Provides detailed coverage of the full range of molecular tools currently available, with expert guidance on the analysis and interpretation of results -Includes step-by-step guidance on standard operational procedures, including molecular tests used in environmental monitoring, with individual chapters devoted to each procedure -Complements the published Handbook of Cyanobacterial Monitoring and Cyanotoxin Analysis from the CyanoCOST project This handbook is an indispensable working resource for scientists, lab technicians, and water management professionals and an excellent text/reference for graduate students and supervisors who use molecular tools. It will also be of great value to environmental health and protection officials and policy makers.
