Results from the Swedish National Screening Programme 2006. Subreport 2: 1,5,9-cyklododecatriene

As an assignment from the Swedish Environmental Protection Agency, IVL has during 2006/2007 performed a 'Screening Study' of 1,5,9-cyclododecatriene. The screening programme included measurements in background areas and in the vicinity of potential point sources. Measurements were also done in urban areas reflecting diffuse emission pathways from society. Sample types were air, soil, sediment, sludge and biota (fish). A total of 55 samples were included. CDDT was not found in any of the samples. The reported detection limits were 0.04 - 0.05 ng/m3 in air, 10 ng/g DW in sediment and soil, 20 ng/g DW in sludge and 1-4 ng/g WW in fish. The overall conclusion is that 1,5,9-cyclododecatriene is generally not present in the Swedish environment in concentration that is of environmental concern. The substance is thus not recommended as a candidate to be included in regular monitoring.
