Studies have shown that CeO2 nanoparticles (NPs) can be accumulated in plants without modification, which could pose a threat for human health. In this research, cilantro (Coriandrum sativum L.) plants were germinated and grown for 30 days in soil amended with 0 to SOO mg kg(-1) CeO2 NPs and analyzed by spectroscopic techniques and biochemical assays. At 125 mg kg(-1), plants produced longer roots (p <= 0.05), and at 500 mg kg(-1), there was higher Ce accumulation in tissues (p <= 0.05). At 125 mg, catalase activity significantly increased in shoots and ascorbate peroxidase in roots (p <= 0.05). The FTIR analyses revealed that at 125 mg kg(-1) the CeO2 NPs changed the chemical environment of carbohydrates in cilantro shoots, for which changes in the area of the stretching frequencies were observed. This suggests that the CeO2 NPs could change the nutritional properties of cilantro.
