摘要：To study the impact of atmospheric Cd exerts on the soil accumulated of Qingdao urban area, atmospheric dust and soil samples are collected and analyzed. Based on these tested samples, this paper firstly analyzed the geochemistry characters of Cd in atmospheric dusts and soils using the statistic analysis method. Then according to the time accumulation model about the influence of Cd exerts on soil, this paper predicates the influence that atmospheric Cd in dust exerts on soil 30 years later. Analysis results show that atmospheric Cd has great influence on the accumulated soil. For example, it can cause the deterioration of soils quality. Therefore, to prevent soil from Cd pollution, the detection and control of atmospheric Cd should be strengthen.; With the development of industry, the contents of atmospheric dust increase obviously, the contents of various heavy metals increase gradually (). The heavy metal of atmospheric Cadmium (abbr. Cd) not only can be accumulated in soils, but also can enter into human body through the respiratory system and the food chain (). Once Cd is accumulated in human body, it can cause urinary system diseases and Itai-itai disease, and finally harm human's body and life safety (). Qingdao, which locates in the eastern part of Shandong province, is an important economic center of the coastal cities as well as a state-level historical and cultural city. Hence, it requires a higher quality of the environment. Therefore, to provide a theoretical basis for Cd pollution and prevention in Qingdao urban area atmospheric dusts and soils, it is necessary to study the impact of atmospheric Cd exerts on the soils accumulation of Qingdao urban area.
