The rules of typical pollutants were simulated by the micro-universe model. In this study, the soil and water samples from 7 heavy metals storage yards of Tianjin Port have been investigated, revealing high Cd pollution in soil. Aquatic microcosm was used to simulate the chemical behavior of lead and cadmium in Tianjin port, and the internal transportation law was found by using the fugacity-based multimedia environmental mathematical model. The results of the model and experiment were consistent, showing that this model is suitable. The results of the model suggest that 61% of the cadmium in the system was sunk into sediment, the rest flowing out with water, and 99% of the lead was sunk into sediment, showing that for cadmium and lead, settling was the main transport process in the aquatic environment, especially for lead. The impact of minerals stored in the open areas is significant, and should be stored in containers without any direct contact with rain. Also, the pollution channel should be kept closed. %R %U http://manu.ykcs.ac.cn/ykcsen/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
