College of Environmental Science amp。 Engineering, Guangzhou University, Guangzhou 510006, China;2. Fujian Academe of Geological Survey, Fuzhou 350011, ChinaAbstract: The region distrabution of rice sample with high heavy metal content in Coastal Region of Fujian Province was study, and the difference for rice breed absorbing heavy metal was analyzed in this paper. Along 10 rice planting areas in Fuji an Littoral area, 185 Paddy samples were collected. By analysed the heavy metal content of this samples, it was showed thant the average values of Cd, Hg, Pb, As, Cu and Zn were , , , , and mgkg 1 respectively and markedly higher than the average values of rice Tawan area. There were % and % samples respectively with Pb and Cd content exceeding the national limited value of brown rice, but only % samples with Hg and As content exceeding the national limited value of brown rice. The rice samples with high Pb, Cdcontianing were distrbuted around developed city as Zhangzhou, Fuzhou, Fuqing city and so on. Different Breed of paddy have different absorptivity to heavy metal, as Changyou 964 has good absorptivity to Cd and Pb, but sticky rice and 803A1527 has low absorptivity to Cd, As and Pb. These finds would provide academic base for the evalution of rice safty and the selecting of low heavy metal sorbing breed. Key words: rice。 heavy metal。 distribution。 coastal region of Fujian province
