Soil Quality Guidelines for the Protection of Environmental and Human Health
Concentration (mg/kg dry weight) Agricultural 0.9
Data are sufficient and adequate to calculate a Soil Quality Guideline for Human Health (SQGHH) and a Soil Quality Guideline for Environmental health (SQGE). Therefore the soil quality guideline is the lower of the two and represents a fully integrated de novo guideline for this land use, derived in accordance with the soil protocol (CCME 1996;2006). The corresponding interim soil quality criterion (CCME 1991) is superseded by the soil quality guideline.
For guidelines derived prior to 2004, differentiation between soil texture (coarse/fine) is not applicable.
Free cyanide refers to the sum of molecular HCN and and the cyanide ion, CN-.
Concentration (mg/kg dry weight) Residential/ parkland 0.9
