Test material

Details on test material:
cis-1,2-Dichlorobut-2-ene used as reference, purchased from Restek (Bellafonte, PA, USA). It is not reported whether trans-isomer was also used for calibration. In the results part, it is reported that 1,2-dichlorobut-2-ene was found

Results and discussion

Any other information on results incl. tables

In Vitoria-Gasteiz (Northern Spain), several VOC (volatile organic compounds), including 1,4-dichlorobut-2-ene, were analyzed in a campaign to find out the concentrations of atmospheric pollutants in urban air during the period January 1999 to December 2002. The detection limit was reported to be 0.01 µg/m3. In 1999, 1,4-dichlorobut-2-ene was registered in a frequency of occurrence of 10.5% with an arithmetic mean of 0.06 µg/m3 (range of concentration: < 0.01 -1.83 µg/m3). In 2000, no 1,4-dichlorobut-2-ene was detected.

Only in 1999, also several other compounds were found with an incidence of less than 25 %: 1,1,1,2-tetrachloroethane, tert-butylbenzene, butylbenzene, bromobenzene, and others. None of these substances was detected in 2000-2002.

Baroja and coworkers concluded that these results were due to an unspecified contamination source. Baroja and coworkers changed the sampling site only in January 2001. In their Conclusions (page 364), Baroja and coworkers also do not mention 1,4-dichlorobut-2-ene and other uncommon substances to occur in urban air.
