SPMEを用いたPAH及びPAEによる土壌汚染調査

抄録

A simple method to measure PAH and PAE in soil without time-counting operations, such as extraction, separation and concentration, or use of a large quantity of organic solvents was developed. Head Space Solid-Phase Microextraction (HS/SPME) method was adopted in the method. The appropriate condition to measure PAE and PAH was decided for the method, and the precision of the method was studied. Then, some samples of soil beside a heavy trafic road and near a plastic molding factory were investigated under the measurement condition decided in this study. The results showed that the density of PAH and PAE in soil decreased with distance from the road or the factory. This means that the HS/SPME method was effective for the measurement of semi-volatile organic matters in soil. With HS/SPME method, we can expect to get more information about the pollution of soil by semi-volatile organic matters like PAH and PAE, because we can execute operations more quickly and measure more samples with less contamination from measurement operations than with common extraction methods.
