Dioxins are widespread in the atmosphere, soil and other environmental media. Because of their special physicochemical and biological properties, they can harm to human health and ecological environment seriously. This paper summarized the present situation of atmospheric pollution of dioxins in various areas in our country, and carried on the contrast analysis. The results showed that the average concentration of atmospheric levels of dioxin in most parts of China were almost unanimous but lower than atmospheric environmental standard limit of Japan. In different functional areas, the differences of dioxins concentration in the atmosphere were great, but the variation trends of dioxins concentration in different functional areas were consistent, and the concentration from high to low was in order of industrial district, residence area, comercial area and background area. This paper can provide the basis for understanding the pollution status of dioxins in the atmosphere of China.
