Management of Legionella in Water Systems
Author: National Academies of Sciences, Engineering, and MedicinePublisher: National Academies Press
ISBN: 030949382X
Category : Medical
Languages : en
Pages : 291
Book Description
Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.
Some Drinking-water Disinfectants and Contaminants, Including Arsenic
Author: IARC Working Group on the Evaluation of Carcinogenic Risks to HumansPublisher: IARC
ISBN: 9789283212843
Category : Medical
Languages : en
Pages : 540
Book Description
A working group of 23 experts from 13 countries met in Lyon to evaluate the evidence for carcinogenicity of arsenic (mostly naturally occurring) as a contaminant of drinking-water, and of the water-disinfectant chloramine. The working group also evaluated or re-evaluated four chlorination by-products found in drinking-water, namely chloral hydrate, di- and trichloroacetic acids, and 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (also known as MX). High-level exposure to arsenic in drinking-water occurs in some regions such as China, Latin America, Bangladesh and West Bengal. The Working Group reviewed epidemiological studies of human cancer (mainly ecological studies in Taiwan and Chile, and several case-control and cohort studies) in relation to arsenic in drinking-water. Arsenic in drinking-water (primarily inorganic, as arsenate and to a lesser extent arsenite) was evaluated as carcinogenic to humans (Group 1) on the basis of sufficient evidence for an increased risk for cancer of the urinary bladder, lung and skin. Studies on inorganic arsenic in experimental animals provided limited evidence for its carcinogenicity, but sufficient evidence was found in experimental animals for the carcinogenicity of dimethylarsinic acid (an organic form of arsenic), which produced urinary bladder tumours in rats and lung tumours in mice after oral administration.

Book Description
Excerpt from Manuals of Health: Water, Air, and Disinfectants Water, Its Properties And Composition. Water-Supply a Necessity with all Communnities - Water an Article of Sale - The Chemistry of Water illustrative of certain Elementary Principles of Chemistry - The invariable Properties of Pure Water - The Terms Pure and Impure Water generally a Difference of Degree - The Impurities of Water, Mineral and Organic - Water a Necessity of active Vitality, and therefore a Food - The Sources of Water - The various Forms of Water, as Ice and Steam - Circulation of Water from Ocean to Atmosphere - Its Descent as Rain - Its Accumulation in the Earth forming Springs - Its Descent to the Sea as Streams and Rivers. The Patriarchs of old dug wells for the use of themselves and their herds and flocks. Those they guarded jealously, and their servants sometimes fought for the possession of the waters, and disputed the right of others to make use of them. Thus did the servants of Abraham and Abimelech fight for the well which Abraham had dug, until an agreement made between them at Beersheba set the matter at rest. The traveller, weary with toil through the day, lights his camp fire in the evening by some running stream or spring. The Arab in his desert wanderings seeks a resting-place beside one of those fountains so rare in sandy plains.
