METHOD OF RESOLVING CONTRIBUTION RATIO TO SOIL CONTAMINATION BY PLURALITY OF POLLUTERS THROUGH SEQUENTIAL EXTRACTION SCHEME AND STABLE ISOTOPE ANALYSIS SCHEME

摘要

In a method of resolving a contribution ratio to soil contamination by a plurality of polluters through a sequential extraction scheme and a stable isotope analysis scheme, Pb stable isotopes are eluted at 5 types of “cation exchange fraction”, “carbonate fraction”, “iron-oxide and manganese hydroxide-fraction”, “organic matters and sulfide fraction”, and “residual fraction” existing at other types and separated from each other in each step. The Pb stable isotopes obtained in each step are analyzed.;The contribution ratio to soil contamination by the polluters is resolved through a predetermined resolving equation using the content of a Pb stable isotope in each step based on the content ratio of the Pb stable isotopes. The Pb stable isotopes are 206Pb and 207Pb.
