N2 - The main purpose of this study is to evaluate the Buddleja species bioaccumulation capacity for the phytoremediation of soils contaminated with chromium produced by tannery effluents. The soils evaluated were collected from the Añashuayco stream, located in Arequipa region. The soil samples were collected from four different locations, in order to determine the presence of total chromium through the Environmental Protection Agency analytical technique, method 3050B acid digestion of sediment, sludge and soil. Three soil samples were analyzed for each collected location. Additionally, two non-contaminated soil samples (control group) were also analyzed. A Buddleja species seedling was placed in each sample to be monitored monthly for up to 90 days. Then, the plant tissue analysis was carried out by the analytical method of atomic absorption spectrophotometry in order to determine the amount of bioaccumulated total chromium. As a result, the Buddleja species bioaccumulated 30.45%, 24.19%, 34.55% and 40.72% of total chromium per each soil sample location in a period of 90 days. Therefore, the Buddleja species can be considered as an alternative to remediate soils contaminated with total chromium that comes from tannery effluents.
