13.6          Appendix F: Explanation of the selection of the soil properties that control the added contaminant limits for copper
A total of ten normalisation relationships were used to normalise the Cu toxicity data. The same ten normalisation relationships were used to generate the soil-specific ACLs. The generated soil-specific ACLs are the concentrations for each species/soil process that correspond to the desired level of protection (for example, 80% for urban residential land/public open space land use). Therefore, in order to provide the desired level of protection, the lowest ACL at each soil property value must be adopted as the final ACL.

For Cu there were six normalisation relationships based on CEC. These
