Concentration (mg/kg dry weight) - Agricultural

1

Data are sufficient and adequate to calculate a provisional Soil Quality Guideline for Human Health (SQGHH) and a Soil Quality Guideline for Environmental health (SQGE). The provisional SQGHH is equal to the SQGE and to the existing interim soil quality criterion (CCME, 1991) and thus becomes the soil quality guideline, which supersedes the interim soil quality criterion for this land use.

 

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

 

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

1

Data are sufficient and adequate to calculate a provisional Soil Quality Guideline for Human Health (SQGHH) and a Soil Quality Guideline for Environmental Health (SQGE). The provisional SQGHH is less than the SQGE and thus becomes the soil quality guideline for this land use.

 

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

 

Concentration (mg/kg dry weight) - Commercial
