Book Synopsis Topics in Public Health by : David Claborn
Download or read book Topics in Public Health written by David Claborn and published by BoD – Books on Demand. This book was released on 2015-06-17 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Public health has been defined as the efforts of a community that allow a population to remain healthy. This definition is very inclusive, so elements of clinical care, health promotion and many other fields contribute to the larger discipline of public health. The profession has evolved in recent years, with the emphasis in the developed world changing from the hygiene method for control of infectious diseases to a more complex approach to address chronic disease. However, the focus in public health continues to be the population. This book provides a sample of fields that contribute to the public health profession. Its broad approach provides examples of the core fields of public health, including environmental health, epidemiology, biostatistics, health administration, and health behavior.

Book Synopsis Detection of Pathogens in Water Using Micro and Nano-Technology by : Giampaolo Zuccheri
Download or read book Detection of Pathogens in Water Using Micro and Nano-Technology written by Giampaolo Zuccheri and published by IWA Publishing. This book was released on 2012-08-14 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detection of Pathogens in Water Using Micro and Nano-Technology aims to promote the uptake of innovative micro and nano-technological approaches towards the development of an integrated, cost-effective nano-biological sensor useful for security and environmental assays. The book describes the concerted efforts of a large European research project and the achievements of additional leading research groups. The reported knowledge and expertise should support in the innovation and integration of often separated unitary processes. Sampling, cell lysis and DNA/RNA extraction, DNA hybridisation detection micro- and nanosensors, microfluidics, together also with computational modelling and risk assessment can be integrated in the framework of the current and evolving European regulations and needs. The development and uptake of molecular methods is revolutionizing the field of waterborne pathogens detection, commonly performed with time-consuming cultural methods. The molecular detection methods are enabling the development of integrated instruments based on biosensor that will ultimately automate the full pathway of the microbiological analysis of water.

Book Synopsis Drinking Water Distribution Systems by : National Research Council
Download or read book Drinking Water Distribution Systems written by National Research Council and published by National Academies Press. This book was released on 2007-01-22 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protecting and maintaining water distributions systems is crucial to ensuring high quality drinking water. Distribution systems-consisting of pipes, pumps, valves, storage tanks, reservoirs, meters, fittings, and other hydraulic appurtenances-carry drinking water from a centralized treatment plant or well supplies to consumers' taps. Spanning almost 1 million miles in the United States, distribution systems represent the vast majority of physical infrastructure for water supplies, and thus constitute the primary management challenge from both an operational and public health standpoint. Recent data on waterborne disease outbreaks suggest that distribution systems remain a source of contamination that has yet to be fully addressed. This report evaluates approaches for risk characterization and recent data, and it identifies a variety of strategies that could be considered to reduce the risks posed by water-quality deteriorating events in distribution systems. Particular attention is given to backflow events via cross connections, the potential for contamination of the distribution system during construction and repair activities, maintenance of storage facilities, and the role of premise plumbing in public health risk. The report also identifies advances in detection, monitoring and modeling, analytical methods, and research and development opportunities that will enable the water supply industry to further reduce risks associated with drinking water distribution systems.

Book Synopsis Heterotrophic Plate Counts and Drinking-water Safety by : Jamie Bartram
Download or read book Heterotrophic Plate Counts and Drinking-water Safety written by Jamie Bartram and published by IWA Publishing. This book was released on 2003-08-31 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heterotrophic Plate Counts and Drinking-water Safety provides a critical assessment of the role of the Heterotrophic Plate Count (HPC) measurement in drinking water quality management. It was developed from an Expert workshop of 32 scientists convened by the World Health Organization and the WHO/NSF International Collaborating Centre for Drinking Water Safety and Treatment in Geneva, Switzerland. Heterotrophs are organisms, including bacteria, yeasts and moulds, that require an external source of organic carbon for growth. The HPC test (or Standard Plate Count), applied in many variants, is the internationally accepted test for measuring the hetrotrophic microorganism population in drinking water, and also other media. It measures only a fraction of the microorganisms actually present and does not distinguish between pathogens and non-pathogens. High levels of microbial growth can affect the taste and odor of drinking water and may indicate the presence of nutrients and biofilms which could harbor pathogens, as well as the possibility that some event has interfered with the normal production of the drinking water. HPC counts also routinely increase in water that has been treated by an in-line device such as a carbon filter or softener, in water-dispensing devices and in bottled waters and indeed in all water that has suitable nutrients, does not have a residual disinfectant, and is kept under sufficient conditions. There is debate among health professionals as to the need, utility or quantitative basis for health-based standards or guidelines relating to HPC-measured regrowth in drinking water. The issues that were addressed in this work include: the relationship between HPC in drinking water (including that derived from in-line treatment systems, dispensers and bottled water) and health risks for the general public the role of HPC as an indirect indicator or index for pathogens of concern in drinking water the role of HPC in assessing the efficacy and proper functioning of water treatment and supply processes the relationship between HPC and the aesthetic acceptability of drinking water. Heterotrophic Plate Counts and Drinking-water Safety provides valuable information on the utility and the limitations of HPC data in the management and operation of piped water systems as well as other means of providing drinking water to the public. It is of particular value to piped public water suppliers and bottled water suppliers, manufacturers and users of water treatment and transmission equipment and inline treatment devices, water engineers, sanitary and clinical microbiologists, and national and local public health officials and regulators of drinking water quality.
Book Synopsis Microbiology of Drinking Water by : Gabriel Bitton
Download or read book Microbiology of Drinking Water written by Gabriel Bitton and published by John Wiley & Sons. This book was released on 2014-10-06 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbiology of Drinking Water Production and Distribution addresses the public health aspects of drinking water treatment and distribution. It explains the different water treatment processes, such as pretreatment, coagulation, flocculation, sedimentation, filtration, disinfection, and their impacts on waterborne microbial pathogens and parasites. Drinking water quality may be degraded in water distribution systems—microorganisms form biofilms within distribution systems that allow them to flourish. Various methodologies have been proposed to assess the bacterial growth potential in water distribution systems. Microbiology of Drinking Water Production and Distribution also places drinking water quality and public health issues in context; it addresses the effect of bioterrorism on drinking water safety, particularly safeguards that are in place to protect consumers against the microbial agents involved. In addition, the text delves into research on drinking water quality in developing countries and the low-cost treatment technologies that could save lives. The text also examines the microbiological water quality of bottled water, often misunderstood by the public at large.
Book Synopsis Protecting Groundwater for Health by : O. Schmoll
Download or read book Protecting Groundwater for Health written by O. Schmoll and published by IWA Publishing. This book was released on 2006-09-30 with total page 699 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protecting drinking-water resources is the first barrier against pathogens and substances hazardous to health. Practitioners in drinking-water supply or surveillance - from the local and technical level up to senior management - have a key role in initiating collaboration with other sectors, such as environment, land-use planning, or agriculture towards safeguarding drinking-water sources. Protecting Groundwater for Health provides a structured approach to analysing hazards to groundwater quality, assessing the risk they may cause for a specific supply, setting priorities in addressing these, and developing management strategies for their control. For health professionals, it thus is a tool for access to environmental information needed for such a process, and for professionals from other sectors, it gives a point of entry for understanding health aspects of groundwater management. This book presents tools for developing strategies to protect groundwater for health by managing the quality of drinking-water sources. Section I covers the natural science background needed to understand which pathogens and chemicals are relevant to human health, how they are transported in the sub-surface and how they may be reduced, removed or retarded. Section II provides guidance for compiling information needed to characterise the drinking-water catchment area in order to assess health hazards potentially reaching groundwater. Section III provides conceptional guidance on prioritising both hazards and management responses. Section IV provides an overview of the potential management actions that may be taken to protect drinking-water sources. These begin with their integration into a comprehensive Water Safety Plan that covers all supply steps from catchment to consumer. Section V provides an overview of measures to prevent pollution from human activities in the catchment, beginning with the overarching issues of policy, land-use planning and implementation for protecting groundwater. Overviews are presented of the specific management approaches that help avoid groundwater pollution from the range of human activities in the catchment, i.e. agriculture, sanitation practices, industry, mining, military sites, waste disposal and traffic.

Book excerpt: Special Offer: KWR Drinking Water Treatment Set - Buy all five books together and save a total £119! Ever since the recognition of the important role of water in the transmission of pathogenic micro-organisms in the 19th century, microbiological safety of drinking water has been a major research issue for microbiologists in the drinking water industry. The main objective of this book is to develop a general strategy to assess elimination capacity of water treatment processes for pathogens. It investigates: The potential use of faecal indicators Coli44, (including E. coli) and SSRC, (including C. perfringens) as process indicators to assess pathogen elimination in full-scale water treatment plants. The value of comparative challenge tests with pre-cultured organisms for the assessment of elimination capacity of full-scale processes, to study the effect of process conditions and to validate the use of process indicators. The use of literature data to assess elimination capacity of water treatment processes for pathogens and the effect of process conditions on this.

Book Synopsis Drinking Water Quality and Human Health by : Patrick Levallois
Download or read book Drinking Water Quality and Human Health written by Patrick Levallois and published by MDPI. This book was released on 2019-04-04 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: The quality of drinking water is paramount for public health. Despite important improvements in the last decades, access to safe drinking water is not universal. The World Health Organization estimates that almost 10% of the population in the world do not have access to improved drinking water sources. Among other diseases, waterborne infections cause diarrhea, which kills nearly one million people every year, mostly children under 5 years of age. On the other hand, chemical pollution is a concern in high-income countries and an increasing problem in low- and middle-income countries. Exposure to chemicals in drinking water may lead to a range of chronic non-communicable diseases (e.g., cancer, cardiovascular disease), adverse reproductive outcomes, and effects on children’s health (e.g., neurodevelopment), among other health effects. Although drinking water quality is regulated and monitored in many countries, increasing knowledge leads to the need for reviewing standards and guidelines on a nearly permanent basis, both for regulated and newly identified contaminants. Drinking water standards are mostly based on animal toxicity data, and more robust epidemiologic studies with accurate exposure assessment are needed. The current risk assessment paradigm dealing mostly with one-by-one chemicals dismisses the potential synergisms or interactions from exposures to mixtures of contaminants, particularly at the low-exposure range. Thus, evidence is needed on exposure and health effects of mixtures of contaminants in drinking water. Finally, water stress and water quality problems are expected to increase in the coming years due to climate change and increasing water demand by population growth, and new evidence is needed to design appropriate adaptation policies. This Special Issue of International Journal of Environmental Research and Public Health (IJERPH) focuses on the current state of knowledge on the links between drinking water quality and human health.
