TI  - Volatile organic components migrating from plastic pipes (HDPE, PEX and PVC) into 
      drinking water.
PG  - 1912-20
AB  - High-density polyethylene pipes (HDPE), crossbonded polyethylene pipes (PEX) and 
      polyvinyl chloride (PVC) pipes for drinking water were tested with respect to 
      migration of volatile organic components (VOC) to water. The odour of water in 
      contact with plastic pipes was assessed according to the quantitative threshold 
      odour number (TON) concept. A major migrating component from HDPE pipes was 
      2,4-di-tert-butyl-phenol (2,4-DTBP) which is a known degradation product from 
      antioxidants such as Irgafos 168(R). In addition, a range of esters, aldehydes, 
      ketones, aromatic hydrocarbons and terpenoids were identified as migration 
      products from HDPE pipes. Water in contact with HDPE pipes was assessed with 
      respect to TON, and values > or =4 were determined for five out of seven brands 
      of HDPE pipes. The total amount of VOC released to water during three successive 
      test periods were fairly constant for the HDPE pipes. Corresponding migration 
      tests carried out for PEX pipes showed that VOC migrated in significant amounts 
      into the test water, and TON >/=5 of the test water were observed in all tests. 
      Several of the migrated VOC were not identified. Oxygenates predominated the 
      identified VOC in the test water from PEX pipes. Migration tests of PVC pipes 
      revealed few volatile migrants in the test samples and no significant odour of 
      the test water.
