MULTIVARIANT STATISTICAL ANALYSIS OF DIOXIN CONGENERS IN SOIL SAMPLE FROM DIFFERENT SITES IN BUSAN, SOUTH KOREA
In this study, soil samples in Busan have been sampled and analysed to determine the level of dioxins, summarize the sysmatic information and provide the major trends of the data. Soil samples collected in 2008 showed concentration ranging from 0.157 to 28.772 pg-TEQ/g dry weight with an mean values of 11.929 pg- TEQ/g dry weight. In the case of real values, OCDD is the major contributor with 53.3％. In contrast to real values, dioxin congeners profiles in TEQ values were dominated by 2,3,4,7,8-PeCDF, which contributed about 36.7％ to the total dioxin concentrations. The ratio of PCDFs/PCDDs in real values was about 0.45, but that in TEQ values was the opposite with approximately 2.4 of the ratio of PCDF/PCDDs. Multivariate data analysis method was adopted in this research to combine a large amount of variables into several underlying compounds, which summarize the sysmatic information and provide the major trends of the data. PCA provides a two dimentional model, which would explain the data variance. The first principal component(PC1) explains 82.4％ of the total variance. The second principal component(PC2) explains 9.0％ of the total variane.
