바이오차 처리 후 토양 잔류 Endosulfan의 경시적 변화에 관한 통계학적 접근

The Ginseng (Panax ginseng C, A, Meyer) is a perennial plant that uses many pesticides to prevent diseases. According to the National Quality Management Service, pesticides such as Endosulfan, Chloropyriphos and Procymidone were detected in ginseng. The Endosulfan used in this study is an organic chlorine pesticide that adversely affects the human central nervous system and was banned from use and manufacture in 2004. This study was carried out to examine reduction product (biochar) and the residual pattern of Endosulfan in ginseng growing filed. Endosulfan detected was quantitated using the analytical methods validated by recovery tests with a GC-μECD/MSD. Repeated Measures ANOVA is used to compare the temporal change of soil residual Endosulfan after Biochar treatment. The repeated measures ANOVA is a member of the ANOVA family. ANOVA is short for Analysis of variance. All ANOVAs compare one or more mean scores with each other； they are tests for the difference in mean scores. The repeated measures ANOVA compares means across one or more variables that are based on repeated observations. A repeated measures ANOVA model can also include zero or more independent variables. Again, a repeated measures ANOVA has at least 1 dependent variable that has more than one observation. According to Repeated Measures ANOVA, the residual concentration of Endosulfan, which was artificially treated in a ginseng cultivated area, was decomposed over time. It has been found that the degradation rate after reducing agents Biochar is enhanced. And the treatment of about 0.8% Biochar based on soil weight is 50% reduction effect of the absorption and transfer of Endosulfan to ginseng.
