Applicant's summary and conclusion
- Conclusions:
- The paper provides regressions between Cu toxicity in plants and soil properties : CEC and pH. The data support the normalization of plant toxicity data
- Executive summary:
The impact of soil properties on metal bioavailability is well recognized. However, the effect of soil bioavailability parameters on toxicity threshold values for Cu in plants needs quantification. Eighteen European soils varying widely in soil properties were amended with CuCl2 to obtain a range of seven concentrations including an unamended control. Two plant toxicity assays, barely root elongation (4d) and tomato shoot growth (21d after emergence), were performed on each soil under controlled environment conditions. The effective concentration of added Cu causing 50 % inhibition (EC50) ranged from 36 to 536 mg/kg soil and from 22 to 851 mg/kg soil for barely root elongation and tomato shoot growth, respectively, representing variation in EC50 among soils of 15- and 39- fold. Single regressions carried out between Cu toxicity threshold values and various soil properties showed that exchangeable calcium and soil cation exchange capacity (CEC; measured at soil pH) were the best single predictors for toxicity values from both plant tests. The inclusion of other soil properties, such as iron oxide concentration, soil pH, clay, or organic carbon content, further improved predictions. For risk assessment, we suggest that Cu toxicity threshold values (EC50) be nomalized on the key soil property of CEC. If available, soil exchangeable calcium and iron oxide concentration would improve the normalization.
