Notes: TOC = total organic carbon. Dry sed. = dry sediment, * = carbonate free base (corrected for carbonate content). ND = not determined, BD = below detection limit. The detection limit of the gas chromatography–mass spectrometry system used for n-alkanes is 250 ng/mL (1 µL injection volume = 50 pg of target substance).
