高铬浓度是威胁environment, since it is persistent and non-biodegradable pollutant while introduced once to our planet. Bioaccumulation capacity of chromium has carcinogenic potential to human beings. To minimize the risk of chromium bioaccumulation, the study was conducted in Wukro irrigation fields. 54 plants, 24 water and 18 soil samples were collected in triplication from the selected points of upstream, treatment plant and downstream of the Sheba leather industry. Samples were transported to advanced laboratory for chromium analysis and results were analysed by R-software. Downstream vegetable samples were measured higher chromium bioaccumulation compared to the upstream sites. Highest chromium concentration was recorded in rood edible vegetables, and the lowest was measured in fruit edible vegetables. Chromium concentration was significantly different between the upstream and downstream vegetables, water and soil samples at p<0.01, p<0.05 and p < 0.001 respectively. The chromium bioaccumulation order were root edible>leaf edible>fruit edible vegetables. Environmental laws have to be strictly enforced and further researches are recommended.
