Notes: Sed. = dry sediment extracted, TOC = total organic carbon. BD = below detection limit. Detection limit for phospholipids is difficult to determine because it can vary depending on the phospholipid class and the different sediment matrixes. For a phosphatidylglycerol standard, detection limit of the liquid chromatography–mass spectrometry system used is ~250 ng/mL (5 µL injection volume = ~1.3 ng of target substance).
