Table 33: Overview over analysed sediments including sample location, year, total organic carbon (TOC)
content and applied methodology. ECNI and CH4/CH2CI2-NICI could not be applied to samples with total
PCA concentrations below ca. 50 ng/g dw due to insufficient sensitivity. Determination of formula and
congener group profiles by ECNI became only possible with new instrumentation at the end of the
project. Samples were re-analysed with ECNI, if a sufficient sample amount still was available (>5 g).
