May not prevent the accumulation of methylmercury in aquatic life, therefore, may not protect wildlife that consume aquatic life. Also, may not fully protect higher trophic level fish. Consult the factsheet for details. Consult equally the methylmercury guideline in the Canadian Tissue Residue Guidelines for the Protection of Wildlife Consumers of Aquatic Biota

Soil Quality for the Protection of Environmental and Human Health

Concentration (mg/kg dry weight) - Agricultural

6.6

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 The corresponding interim soil quality criterion (CCME 1991) is superseded by the soil quality guideline.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.
