| Migration of organic substrates from polymer pipelines to tap water may result in deterioration of organoleptic water properties, especially its odor and flavor. The aim of the presented studies was to determine the threshold odor number (TON) and threshold flavor number (TFN) for water after its contact with plastic water supply pipelines. Unplasticized polyvinyl chloride PVC-U (33.4 mm x 2.2 mm), high density polyethylene PE-HD (32 mm x 2.4 mm) and cross-linked polyethylene PEX-b (28.6 nnm x 3.2 mm) were selected for studies. The analysis procedure covered pipe sample flushing with ultra pure water for 1 hour, sample storage in ultra pure water for 24 hours at 23 degrees C, test for contaminant migration within 72 h (according to EN 1420-1:1999), dilution, and TON and TFN assessment by the complete and even method of the unforced choice (according to EN 1622:2006). The odor and flavor testing team consisted of 5 individuals, the measurements were repeated 3 times. The average calculated TON was in the range of 3-5 while TFN - 3-6. The highest value was observed for PE-HD and the lowest for PVC-U. Our studies demonstrated that PE-HD had the highest influence on organoleptic properties of water among the analyzed polymer materials, while the lowest influence was observed for PVC-U. |
