英文摘要	In some studies, the researchers pretreated and measured organic carbon, nitrogen and their isotopes (delta C-13 and delta N-15) of marine sediment together, to save costs and resources of analysis. However, the procedure of acidification to remove inorganic carbon for analysing delta C-13 can affect the values of nitrogen and delta N-15, and the biases vary a lot depending on the CaCO3 contents of sediments. In this study, the biases of total nitrogen (TN) and delta N-15 values arising from acidified sediments were compared between the CaCO3-poor (1%-16%) and CaCO3-rich (20%-40%) samples. TN and delta N-15 values were altered during acid treatment (without centrifugation) that possibly led to N-containing compounds volatilization. For CaCO3-poor samples, acidification led to a range of 0%-40% TN losses and 0 parts per thousand-2 parts per thousand shift in delta N-15 values; and 10%-60% TN losses and 1 parts per thousand-14 parts per thousand shift in delta N-15 values for CaCO3-rich samples. The biases from most samples exceeded the precision of the instrument (0.002% for TN and 0.08 parts per thousand for delta N-15), and high biases could mislead our judgment for the environmental implication of the data. Thus, avoiding co-analysis of organic carbon, nitrogen and their isotopes (delta C-13 and delta N-15) in sediments, even for CaCO3-poor marine sediments, is necessary.
