Abstract: Cadmium concentration were determined in eighteen vegetables of Brassica Cruciferae cultivated in greenhouse by atomic absorption spectrophotometry. The difference of cadmium uptake and accumulation are significant in the different vegetable kinds and breeds in Brassica when soil cadmium concentration is 20 mg/kg. Beijing xiaoza 55(Chinese cabbage) has the highest Shoot cadmium concentration that is 61.4 mg/kg; Hong Kong baihua's (Chinese kale) shoot cadmium concentration, however, is only 18.6 mg/kg、. BAF among all the species vegetables exist significant difference. The BAF of xiaoza 55(Chinese cabbage) is high to 3.07. But that of Hong Kong baihua (Chinese kale) and jinqiuhong2 was just 0.93, 0.97 respectively. Both were less than 1. The edible part safety of vegetables will be higher if Hong Kong baihua (Chinese kale) and jinqiuhong2 are planted on the light cadmium contaminated farmland.
