Available in PDF, EPUB and Kindle. Book excerpt: La fluoration artificielle de l'eau est une méthode employée en tant que moyen de prévention de la carie dentaire. Il s'agit d'un traitement de l'eau dont le but est d'ajuster de façon « optimale » la concentration en fluorure dans l'eau potable pour la prévention de la carie dentaire, par l'ajout d'un composé fluoré. La fluoration de l'eau fait l'objet d'un débat de société depuis le début des années 1950. La théorie du cycle hydrosocial nous invite à réfléchir sur la manière dont l'eau et la société se définissent et se redéfinissent mutuellement dans le temps et dans l'espace. Cette théorie nous permet d'aborder l'étude du sujet de la fluoration avec une nouvelle perspective d'analyse. Il y a peu d'études en sciences sociales qui portent sur le sujet de la fluoration, généralement abordé d'un point de vue des sciences de la santé. Nous proposons de décrire le processus de production des eaux fluorées dans un contexte hydrosocial. Ce mémoire est structuré en quatre chapitres. Nous commençons par familiariser le lecteur avec la théorie du cycle hydrosocial. Ensuite, nous faisons une mise en contexte de la fluoration de l'eau, d'une part en présentant un état des lieux, et d'autre part en présentant ce en quoi consiste la pratique de la fluoration de l'eau. Après avoir familiarisé le lecteur avec les thèmes généraux concernant la fluoration de l'eau, nous proposons de reconstituer une histoire hydrosociale de la fluoration. Cette histoire nous permet de mettre en évidence les relations hydrosociales desquelles découle la production des eaux fluorées. L'histoire hydrosociale de la fluoration comporte une phase contemporaine que nous abordons en présentant les principales idées de l'opposition à la fluoration artificielle de l'eau à l'aide notamment d'une analyse iconographique d'images portant sur le thème de la fluoration. Finalement, nous discutons des implications de la théorie du cycle hydrosocial pour étudier la problématique de la fluoration.

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.

Extrait: Eau pluviale est le nom que l'on donne a l'eau de pluie apres qu'elle a touche le sol ou une surface construite ou naturelle susceptible de l'intercepter ou de la recuperer (toiture, terrasse, arbre..). La qualite de l'eau de pluie reflete celle de l'air. Elle a donc beaucoup evolue dans l'espace et dans le temps. En France, les premieres analyses d'eaux pluviales semblent avoir ete faites a Paris, vers 1850 . A cette epoque, la pluie de Paris etait chargee d'arsenic, issue de l'industrie et de la combustion du charbon et charbon de bois) . Elle contenait aussi beaucoup d'ammoniaque (retombee evaluee a 16 kg d'ammoniaque par hectare et par an ) provenant sans doute de la degradation de l'urine des chevaux et des parisiens (avant le tout a l'egout ). Entre les deux guerres, les quantites de soufre (liberees par l'industrie, l'essence et le chauffage au charbon) ont fortement acidifie les...
