Research Abstract	Measurement of stable nitrogen isotope ratio of particulate organicmatter in lakes can provide valuable insights into sources and past biologically mediated nitrogen reactions. Therefore, understandings of the factors controlling isotopic variability of particulate organic nitrogen are essential. This study showed some of factors controlling isotopic variability during decomposition process using compound-specific isotopic measurement technique.
