SIMULATION OF MULTI-MEDIA TRANSFER AND FATE OF PCDD/Fs IN CHINA

摘要：

The environmental behaviors of PCDD/Fs in China are simulated by level Ⅲ fugacity model. The considered compounds are 2,3,7,8-TCDD and OCDD, they are chosen among all 17 toxic PCDD/Fs for great physiochemical properties discrepancy. All simulated results are consistent with the measured ones. It shows that advection inflow of PCDD/Fs from atmosphere is main source. Our result also suggests that soil is the main sink of PCDD/Fs, and transportation from air to soil is dominating process. PCDD/ Fs concentrations in environmental media are sensitive to the temperature and precipitation through analyzing the sensitivity of all inputs. It can be predicted the variation of concentration and transport, by simulating the change of temperature and precipitation according the climate of China.
