Bioaccessibility of each REE was determined by extraction with 0.01 M CaCl2, which for all three REEs in this soil was quite low, <0.10% of total. Averaged over all REEs and endpoints, durum wheat was more tolerant than radish and tomato and averaged over all endpoints, Eu appeared to be the most phytotoxic of the three REEs. EC10 expressed as total soil had a more than twenty-fold range, from 337 mg/kg to more than >8000 mg/kg. Toxicity thresholds (ECx) for radish, tomato, and durum wheat growth endpoints (shoot length, shoot mass, root length) to Ce, Nd or Eu added to a black organic soil were determined from 14-day dose-response growth assays. However, in areas where REE contamination is likely, the slow accumulation of these elements in the environment could become problematic. From values measured in natural soils around the world, our results continue to support the notion that REEs are of limited toxicity and not considered extremely hazardous to the environment. Concentration of Ce in aboveground biomass was lower than root Ce content, and followed the dose-response trend. canadense) with all REEs and on all species tested with Ce in both soil pH treatments. However, effects on growth were more pronounced, with detectable inhibition concentrations causing 10% and 25% reductions in biomass for the two native forb species (A. Effects on germination were mostly observed with Ce at low pH. Ce was also tested at two pH levels and plant tissue analysis was conducted on pooled samples. Effects of REE dose on germination were established through measures of total percent germination and speed of germination effects on growth were established through determination of above ground biomass. In separate experiments, seven to eight doses of each element were added to the soil prior to sowing seeds. and switchgrass, Panicum virgatum L.) and two commonly used crop species (radish, Raphanus sativus L., and tomato, Solanum lycopersicum L.) to the REEs lanthanum (La), yttrium (Y) and cerium (Ce) were tested. The exposure-response relationships of three native Canadian plant species (common milkweed, Asclepias syriaca L., showy ticktrefoil, Desmodium canadense (L.) DC.
