Disinfection process, mainly with chlorine, to prevent microbiological contamination of water can lead to the formation of hazardous disinfection by-products(DBPs) due to the reaction of chlorine with natural organic matter(NOM) present in the water.... Beyond specific health based thresholds, DBPs can represent a public health issue due to the potential chronic risk of adverse effects on human health(e. g., cancer, reproductive and developmental effects) and the high prevalence of exposure. Thus, DBPs constitute an important concern for water systems, especially systems supplied by surface waters.... Recently, a technique known as differential UV [ultraviolet] absorbance(DUVA) has been developed that could provide a sensitive and highly specific indicator for DBP formation resulting from chlorination. 2, record 1, English, - differential%20UV%20absorbance

[Des auteurs] ont publié un rapport sur l'utilisation de la méthode du différentiel d'absorbance UV [ultraviolet] (DAUV) pour estimer la formation des SPD [sous-produits de désinfection]. Cette méthode est basée sur le principe que la matière organique absorbe la lumière. Lorsque le chlore entre en contact avec la matière organique, celle-ci s'oxyde, ce qui entraine la formation de SPD, mais aussi une diminution de la capacité de la matière organique à absorber la lumière (absorbance). [...] Les auteurs soulignent que cette méthode peut s'avérer un outil fort utile pour le suivi des SPD dans les réseaux de distribution et dans les stations de traitement, en permettant de sauver temps et argent pour les analyses. 2, record 1, French, - diff%C3%A9rentiel%20d%27absorbance%20UV

Record number: 2, Textual support number: 1 OBS
During fermentation organic matter is decomposed in the absence of air(oxygen) ;hence, there is always an accumulation of reduction products, or incomplete oxidation products.... There are also many microbiological processes that go on in the presence of air while yielding incomplete oxidation products. Good examples are the formation of acetic acid(vinegar) from alcohol by vinegar bacteria, and of citric acid from sugar by certain molds.... 4, record 2, English, - aerobic%20fermentation

fermentation : Transformation de la matière organique sous l'influence d'organismes microscopiques qui sécrètent des enzymes. [...] Elle peut se produire en l'absence d'oxygène libre (fermentation anaérobie, telle la transformation du sucre en alcool et en gaz carbonique sous l'influence des levures) ou à l'air libre (fermentation aérobie, telle la transformation de l'alcool en acide acétique, ou vinaigre). 3, record 2, French, - fermentation%20a%C3%A9robie

La fermentation de la matière végétale. On distingue deux types de fermentation : 1. La première a lieu à l'air libre : elle est appelée dégradation aérobie. L'activité de certaines bactéries provoque la décomposition de la matière végétale. Cette décomposition dégage du gaz carbonique et de l'ammoniaque. Elle donne un sous-produit solide, le compost, qui est un excellent engrais naturel. [...] 2. La fermentation méthanique. 4, record 2, French, - fermentation%20a%C3%A9robie
