In order to improve and revise the Soil Pollution Control Standard and its researching structure, this relevant project has collected and summarized the relevant information. Also, this project proposes suggestions for the Soil Pollution Control Standard amendment for dioxin pollution. After the soil profiles investigation of 33 locations of representative soil series in New Taipei, Miaoli, Nantou, Chiayi, Yilan, Hualien, Taitung and the industrial zones, this project has completed soil sampling and soil property analysis of 164 samples of layered soil. Trace metal element analysis of 306 soil samples has also been completed to build the necessary soil characteristic parameters for pollution transmission evaluation and risk assessments. Simultaneously, this project has used the soil characteristic parameters with the soil pollution transmission mode to build a quality index of heavy metal mobility in soil environment. To provide soil survey information, background concentration data of baseline, trial calculation, and statistical analysis function of soil quality index for every region, this project has also completed the establishment of the national soil property database, and integrated the relevant soil characteristic investigation data which was completed by EPA and related units over these years.
