| 英文摘要 | this study examined the distributions and stable carbon isotopic compositions of saturated fatty acids (safas) in one 300 cm long sedimentary profile, which was named as site4b in shenhu, northern south china sea. the concentrations of total safas in sediments ranged from 1.80 to 10.16 mu g/g (mu g fa/g dry sediment) and showed an even-over-odd predominance in the carbon chain of c-12 to c-32, mostly with n-c-16 and n-c-18 being the two major components. the short-chain fatty acids (scfas; n-c-12 to n-c-18) mainly from marine microorganisms had average delta c-13 values of -26.7 parts per thousand to -28.2 parts per thousand, whereas some terrigenous-sourced long-chain fatty acids (lcfas; n-c-21 to n-c-32) had average delta c-13 values of -29.6 parts per thousand to -34.1 parts per thousand. the other lcfas (n-c-24 & n-c-26 similar to n-c-28; average delta c-13 values are -26.1 parts per thousand to -28.0 parts per thousand) as well as n-c-19 and n-c-20 safas (average delta c-13 values are -29.1 parts per thousand and -29.3 parts per thousand, respectively) showed a mixed signal of carbon isotope compositions. |
