Book Synopsis Soft Mass Spectrometry in Drinking Water Analysis Using Differential Ion Mobility Spectroscopy by : Jadwiga Lyczko

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of labile ions that easily decompose at various stages of the analytical process is a significant challenge for any analytical method. In this thesis, a new analytical approach based on "soft" mass spectrometry and differential ion mobility was developed that enables the detection of such labile analytes in a quick and convenient fashion, without the need for extensive sample preparation and column separation. Soft mass spectrometry approach combines techniques of electrospray ionization (ESI), differential ion mobility spectroscopy (FAIMS) and mass/tandem mass spectrometry (QTOF-MS/MS). The key feature of ESI-FAIMS-QTOF-MS is the replacement of liquid chromatography by a FAIMS separation technique which eliminates chemical background during the analysis. It also improves the quality of spectral data and provides the detection of thousands of analytes down to a part-per-trillion concentration level. Most importantly, the technique offers extremely soft conditions for ion introduction and their transport through the mass spectrometer. The greatest advantage, in using the soft mass spectrometry approach is that fragile species which were beyond the scope of conventional mass spectrometry approaches can now be analyzed. This thesis demonstrates unique capabilities of the soft ESI-FAIMS-QTOF-MS technique in non-target analysis, which led to the discovery of sulphur-containing polar congeners of thiotetronic acids (TA) in drinking water from underground sources in Canada, United States and Europe. Polar TAs accumulate in underground aquifers and appear to be the most abundant class of organic compounds in groundwater but cannot be detected by conventional mass spectrometry methods due to their extremely fragile nature. Structural elucidation of TAs detected in this study was accomplished using de novo identification approach in which the elemental composition from accurate mass measurements and the manual interpretation of MS/MS data were utilized. TA derivatives were originally isolated from soil bacteria and are investigated in the pharmaceutical industry for their potent activity against a broad spectrum of pathogenic bacteria and negligible toxicity to mammals. We suspect, TA congeners characterized in this study are natural disinfection agents protecting groundwater from bacterial contamination and have minimal biological impact on humans.

Book Synopsis Identifying Future Drinking Water Contaminants by : National Research Council
Download or read book Identifying Future Drinking Water Contaminants written by National Research Council and published by National Academies Press. This book was released on 1999-09-30 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an increasing population, use of new and diverse chemicals that can enter the water supply, and emergence of new microbial pathogens, the U.S. federal government is faced with a regulatory dilemma: Where should it focus its attention and limited resources to ensure safe drinking water supplies for the future? Identifying Future Drinking Water Contaminants is based on a 1998 workshop on emerging drinking water contaminants. It includes a dozen papers that were presented on new and emerging microbiological and chemical drinking water contaminants, associated analytical and water treatment methods for their detection and removal, and existing and proposed environmental databases to assist in their proactive identification and regulation. The papers are preceded by a conceptual approach and related recommendations to EPA for the periodic creation of future Drinking Water Contaminant Candidate Lists (CCLsâ€"produced every five yearsâ€"include currently unregulated chemical and microbiological substances that are known or anticipated to occur in public water systems and that may pose health risks).

Book excerpt: Environmental health has evolved over time into a complex, multidisciplinary field. Many of the key determinants and solutions to environmental health problems lie outside the direct realm of health and are strongly dependent on environmental changes, water and sanitation, industrial development, education, employment, trade, tourism, agriculture, urbanization, energy, housing and national security. Environmental risks, vulnerability and variability manifest themselves in different ways and at different time scales. While there are shared global and transnational problems, each community, country or region faces its own unique environmental health problems, the solution of which depends on circumstances surrounding the resources, customs, institutions, values and environmental vulnerability. This work contains critical reviews and assessments of environmental health practices and research that have worked in places and thus can guide programs and economic development in other countries or regions. The Encyclopedia of Environmental Health, Five Volume Set seeks to conceptualize the subject more clearly, to describe the best available scientific methods that can be used in characterizing and managing environmental health risks, to extend the field of environmental health through new theoretical perspectives and heightened appreciation of social, economic and political contexts, and to encourage a richer analysis in the field through examples of diverse experiences in dealing with the health-environment interface. The Encyclopedia of Environmental Health contains numerous examples of policy options and environmental health practices that have worked and thus can guide programs in other countries or regions It includes a wide range of tools and strategies that can assist communities and countries in assessing environmental health conditions, monitoring progress of intervention implementation and evaluating outcomes Provides a comprehensive overview of existing knowledge in this emerging field Articles contain summaries and assessments of environmental health practices and research, providing a framework for further research Places environmental health in the broader context of environmental change and related ecological, political, economic, social, and cultural issues
