24. Soil-specific added contaminant limits based on no observed effect concentration and 10% effect concentration toxicity data (ACL(NOEC & EC10), mg/kg) for aged zinc (Zn) contamination that should theoretically provide the appropriate level of protection (i.e. 99, 80 or 60% of species) to soil processes, soil invertebrate species and plant species in soils with a pH ranging from 4.0 to 7.5 and CEC values ranging from 5 to 60 cmolc/kg. These are the recommended ACL(NOEC & EC10) values for Zn in aged contaminated soils with each land use.
