ABC and SQG(NOEC & EC10) values are:
ACL(NOEC & EC10):   400 mg/kg
ABC:    10 mg/kg
SQG(NOEC & EC10):   410 mg/kg

9.7.4         Calculation of soil quality guidelines for aged nickel contamination based on LOEC and 30% effect concentration toxicity data, and on 50% effect concentration data

9.7.4.1         Calculation of soil-specific added contaminant limits
Soil-specific aged Ni ACL values based on LOEC and EC30 and on EC50 data were calculated using the method previously set out, except the type of toxicity data used was different. The resulting ACLs are presented in Table 81.
