1. 1. Exposure to trichloramine, trihalomethanes and endotoxins : adverse respiratory and ocular effects among Swedish indoor swimming pool workers

   Författare :Jessica Westerlund; Pål Graff; Louise Fornander; Håkan Löfstedt; Christer Janson; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Trichloramine; trihalomethanes; endotoxins; occupational exposure; ocular health effects; respiratory health effects; swimming pool facilities;

   Sammanfattning : Indoor swimming pool facilities often use chlorine for pool water disinfection. Chlorine can also contribute to the formation of unwanted disinfection byproducts (DBPs). Trichloramine and trihalomethanes (THMs) are DBPs formed in swimming pool water and swimming pool air causing occupational exposure. LÄS MER

   Sammanfattning : Volcanic ash, pumice and Moringa oleifera (M. oleifera) were investigated as indigenous materials for removal of natural organic matter (NOM) at Kampala and Masaka water treatment plants in Uganda. LÄS MER

4. 3. Application of indigenous materials in drinking water treatment

   Sammanfattning : Volcanic ash and Moringa oleifera (M. oleifera) were investigated as indigenous materials for drinking water treatment based on problems identified at Kampala and Masaka water treatment plants in Uganda. LÄS MER

5. 4. Occupational exposure to trichloramine and trihalomethanes : adverse respiratory and ocular effects among Swedish indoor swimming pool workers

   Författare :Jessica Westerlund; Håkan Westberg; Nils Plato; Sandra Johannesson; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicin; Biomedicine;

   Sammanfattning : Occupational exposure in swimming pool facilities related to disinfection by-products (DBPs) has been an issue for the last 15 years. Trichloramine (NCl3) and trihalomethanes (THMs) are DBPs formed in swimming pool water following a reaction between organic matter containing nitrogen or organic or inorganic matter, and chlorine.

7. 5. Removal of Natural Organic Matter to reduce the presence of Trihalomethanes in drinking water

   Författare :Indiana Garcia; Luis Moreno; Bhekie B. Mamba; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi;

   Sammanfattning : In countries located in tropical zones, a critical task in drinking water plants is the removal of the natural organic matter (NOM), particularly during the rainy season when a lot of organic matter is transported by run-off into the water bodies. It provokes overloaded in the plants and they have often needed to be shut down. LÄS MER
