The uptake and translocation of hexavalent chromium (Cr (VI)) by four ornamental plant species was investigated. Aptenia cordofolia L., Brassica juncea L., Brassica oleracea L., and Alyssum maritima L. species were planted in peat growth medium and exposed to Cr (VI) with irrigation water in a range of concentrations from 0.05 to 1 mmol.l(-1) for 10 weeks. The results found in this study indicated that the Cr (VI) concentrations in irrigation water significantly affected the Cr uptake and translocation capacities and the growth responses of all four plants. The increases in the concentration of the Cr (VI) in the irrigation water increased the accumulation and translocation of Cr in the root and shoot of the plants. The Cr concentrations found in the shoots of tested plants were relatively low in comparison with the plants classified as Cr-hyperaccumulators. The Cr accumulation in the shoot of tested plants was recorded in the order of Alyssum maritima L. > Aptenia cordofolia L. > Brassica oleracea L. > Brassica juncea L., for the root the order was Brassica juncea L. > Brassica oleracea L. > Alyssum maritima L. > Aptenia cordofolia L.
