Application of Quinone Biomarker to the Analysis of Hillslope Runoff

Abstract

An applicability of quinone biomarker to the analysis of hillslope runoff was investigated. Atfirst, quinone profiles of three types of stream as well as a hillslope runoff in a forest head were compared. The quinone composition of hillslope runoff differed from others. Moreover, there were remarkable differences in quinone profile of hillslope runoff under different rainfall conditions. Then, the behavior of quinone biomarker accompanying the increase and decrease of hillslope runoff after a rainfall event was examined. Q-9 (1-12), Q-10 (H2), Q-11, MK-6 and MK-10 can be key biomarkers for the analysis of intedlow.
