TI  - White HDPE bottles as source of serious contamination of water samples with Ba 
      and Zn.
PG  - 292-6
AB  - During a recent study of surface water quality factory new white high-density 
      polyethylene (HDPE) bottles were used for collecting the water samples. According 
      to the established field protocol of the Geological Survey of Norway the bottles 
      were twice carefully rinsed with water in the field prior to sampling. Several 
      blank samples using milli-Q (ELGA) water (>18.2 MOmega) were also prepared. On 
      checking the analytical results the blanks returned values of Ag, Ba, Sr, V, Zn 
      and Zr. For Ba and Zn the values (c. 300 microg/l and 95 microg/l) were about 10 
      times above the concentrations that can be expected in natural waters. A 
      laboratory test of the bottles demonstrated that the bottles contaminate the 
      samples with significant amounts of Ba and Zn and some Sr. Simple acid washing of 
      the bottles prior to use did not solve the contamination problem for Ba and Zn. 
      The results suggest that there may exist "clean" and "dirty" HDPE bottles 
      depending on manufacturer/production process. When collecting water samples it is 
      mandatory to check bottles regularly as a possible source of contamination.
