An analytical method for determination of haloacetamides in chlorinated water

Chlorination by-products (CBPs) are produced after chlorine reaction with organic matter that is naturally present in water. Haloacetamides are CBPs that contain nitrogen, an element that is present in precursors known as humic acids. Haloacetamides are among the less studied world wide CBPs and the most polar organic compounds.

An analytical method for the analysis of chloroacetamides in water has been developed and presented in this paper. They can be analysed using gas chromatography with electron capture detector. Sample preparation includes liquid-liquid extraction with an organic solvent of medium polarity and its phase condensation.. Detection limit, recovery as well as relative standard deviation were investigated under the optimized experimental conditions. There is also an attempt to reduce the detection limit to a level close to Athens potable water levels that are quite low due to low raw water dissolved organic carbon (DOC) levels. The purpose of this study is to propose an optimized method for the determination of the analytes mentioned above.

Biofilms on aged Materials in Household Installation Systems

The causes of contamination originate in the water itself and on materials in contact with water. Drinking water is not sterile and does not have to be. Water treatment plants’ strategy consists in removing the nutrients that bacteria feed on to produce “biostable” drinking water. This allows in many cases chlorination to be avoided. But it is known that even biologically stable drinking water with very low nutrient content still contains micro-organisms. These micro-organisms can multiply themselves if they encounter nutrients.

Trinkwasser-Installationen als potenzielle Infektionsquellen für Legionellen rücken immer mehr in das Bewusstsein von Gesundheitsämtern und Verantwortlichen für Trinkwasser-Installationen. Dass es auch andere Übertragungswege gibt, zeigen die Legionelleninfektionen im Raum Ulm/Neu-Ulm.

Formation of THMs during typical dissolved organic nitrogen alanine chlorination in drinking water
© Aristotle University of Thessaloniki (6/2009)
Owing to its low cost, chlorine is globally the most used chemical oxidant for drinking water disinfection. However, there is an unintended consequence of disinfection, the generation of chemical disinfection byproducts (DBPs), especially trihalomethanes (THMs). Dissolved organic nitrogen (DON) as the important precursor of DBPs is of current concern. As alanine (Ala) occurs in much source water, we studied formation pathways for THMs during chlorination of model alanine.

Umweltpreis für Schnellerkennung - Gewässerüberwachung per Handy
© Deutscher Fachverlag (DFV) (9/2008)
In Gewässer eingeleitete Gifte können schwere Schäden verursachen. Ein Schnellsystem zur Überwachung solcher Umweltschäden, das Veränderungen via Handy an einen Rechner liefert, haben Forscher des Heinz Nixdorf-Lehrstuhls für Medizinische Elektronik der TU München entwickelt. Dafür erhielten sie den E.ON-Umweltpreis 2008.
