Screening bulk geochemical analysis of two Artic lake sediment samples prepared by freeze-drying displayed unexpectedly high contents of labile organic matter (OM) represented by the Rock–Eval S1 peaks (e.g., 8.12 and 4.84 mg HC/g sediment). The amount of labile OM was reduced greatly for the freeze-dried sediment samples after a thorough cleaning of the freeze-drier sample chamber (e.g., 2.75 and 1.46 mg HC/g sediment), but was still significantly higher than that of the equivalent air-dried samples (e.g., 0.76 and 0.23 mg HC/g sediment). 2023-08-07T03:54:13Z 2023-08-07T03:54:13Z 2023 Book https://link.springer.com/article/10.1007/s10653-023-01594-9 https://dlib.phenikaa-uni.edu.vn/handle/PNK/8707 en application/pdf Springer |
