hyperaccumulation ofcadmiumand dnachanges in popularvegetable, brassica chinensis l.

brassica chinensis l. is a popular vegetable, especially in asian dishes. for plant growing withinorganic fertilizer, cadmium (cd) has been one of the highest metal and health-risk factors included. thisresearch aimed to assess the bioaccumulation of cd by the plant and its genetic changes. the plant was grownin the soil supplemented by cd at 0, 15, 30, 60 and 120 mg/kg. the accumulations in the roots, stems andleaves, were analyzed using atomic absorption spectrophotometer (aas), then the bioconcentration factor(bcf) and translocation factor (tf) were calculated. dna changes were accessed by random amplifiedpolymorphic dna (rapd) with genomic template stability (gts) tests. the cd accumulation in the plantparts after 30 days of the treatments ranged from 80.93 to 5053.48 mg/kg, 35.53 to 2439.61 mg/kg, and 21.21 to2231.02 mg/kg, respectively. the bcf and tf values ranged from 4.54 to 12.66 and 0.70 to 1.67, respectively.from rapd fingerprints, the gts values ranged from 51.34 to 80.96%. at the highest concentration of cdsupplemented (120 mg/kg), the dna resulted in the highest changes (gts = 51.34%). these results, includingbcf and tf values, also indicated that b. chinensis is a cd-hyperaccumulator, therefore, consuming the plantsgrowing in the cd-polluted area is a health risk
