Ce accumulation in plants was minimally affected by the interactions between CeO2 ENPs and biochar in soil matrices. Biochar variety and soil type impacted Ce uptake, pigment production and lipid peroxidation content in plants. CeO2 associated with soil and biochar surfaces remained in the same chemical form/oxidation state after 28 days.
