Due to the extraordinary ability of biochars to bind organic compounds, plant uptake experiments were conducted to assess the effect of soil-amendment of three different biochars on the uptake of APIs from spiked soil. Methods: Pot experiments were undertaken to assess the extent of sorption and corresponding bioaccessibility of two APIs (carbamazepine - CBZ and propranolol -PRL) to ryegrass (Lolium perenne) grown in an API-spiked loamy sand, with and without biochar amendment (5t/ha equivalent). The soil was amended with three different biochars produced from eucalyptus wood and wheat residues. Results: Both APIs were taken up by ryegrass, with CBZ preferentially accumulated (14.3mg/kg CBZ, 3.8mg/kg PRL in unamended soil) due to its comparatively high concentration in porewater. Soil amendment with biochars increased partitioning of the two APIs by up to three- fold, with corresponding decreases in porewater (34-72% of unamended soil) and plant tissue (17-64%) concentrations. Conclusions: Biochars were effective in reducing the uptake of APIs into plant tissues from a contaminated soil and may be effective in the management of API residues in contaminated soils.
