Soil Quality for the Protection of Environmental and Human Health

Concentration (mg/kg dry weight) - Agricultural

0.4

Data are sufficient and adequate to calculate only a provisional Soil Quality Guideline for Environmental Health (SQGE), which is less than the existing interim soil quality criterion (CCME, 1991). Therefore the provisional soil quality guideline supersedes the interim soil quality guideline.

For guidelines derived prior to 2004, differentiation between soil texture (coarse/fine) is not applicable.

Concentration (mg/kg dry weight) - Residential / parkland

0.4

Data are sufficient and adequate to calculate only a provisional Soil Quality Guideline for Environmental Health (SQGE), which is less than the existing interim soil quality criterion (CCME, 1991). Therefore the provisional soil quality guideline supersedes the interim soil quality guideline.

For guidelines derived prior to 2004, differentiation between soil texture (coarse/fine) is not applicable.

Concentration (mg/kg dry weight) - Commercial

1.4

Data are sufficient and adequate to calculate only a provisional Soil Quality Guideline for Environmental Health (SQGE), which is less than the existing interim soil quality criterion (CCME, 1991). Therefore the provisional soil quality guideline supersedes the interim soil quality guideline.
