“…It is well known that phosphates widely exist in the environment and are used as a basic component of many culture media for toxicity testing. A recent study has also confirmed that the phytotoxicity to romaine lettuce of CeO 2 NPs was determined by phosphates in a sand culture (Zhang et al 2017). Lin and Xing (2008) investigated the phytotoxicity of ZnO NPs on Lolium perenne (ryegrass), and found that concentrated ZnO NPs in the rhizosphere solution and absorbed on the root surface caused potential effects on the plant's growth.…”

“…Kidney bean plants exposed to CeO 2 NPs for 52 days in a low organic matter soil usually possessed higher Ce concentration than the same tissues collected from an organic matter-enriched soil (Majumdar et al 2016). Likewise, different levels of phytotoxicity caused by CeO 2 NPs were found in lettuce seedlings incubated with three kinds of media, including agar (Cui et al 2014), potting mix soil and sand (Zhang et al 2017). Schlich and HundRinke (2015) showed that Ag NP toxicity decreased with increasing clay content and pH, but seemed to be unaffected by the organic carbon content of the soil.…”

“…These results demonstrate that CeO 2 -NPs undergo very limited transformation in the wheat/soil system as consistently noted in previous synchrotron studies (Table S9 †). [29][30][31][32] However, this is the first study to exhibit synchrotron localization and speciation of CeO 2 -NPs in the rhizosphere (i.e. soil-root interface and areas in root vicinity).…”
