Concentration (mg/kg dry weight) - Agricultural

Table
Guideline Coarse Fine
Xylenes (mg/kg)    
Surface (≤1.5m) 11 2.4
Subsoil (>1.5m) 11 2.4

Notes:
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 and de novo guideline for this land use.

Free-phase formation, a circumstance deemed unacceptable by many jurisdictions, occurs when a substance exceeds its solubility limit in soil water. The concentration at which this occurs is dependent on a number of factors, including soil texture, porosity, and aeration porosity. Under the assumptions used for this guideline, at concentrations greater than 600 mg·kg-1 in coarse soil, or 610 mg·kg-1 in fine soil, formation of free-phase toluene will likely occur. Contact jurisdiction for guidance.
