↵1 Extracted concentration = concentration in extract − concentration in control.
↵2 Mean concentrations of two replicates per material.
↵3 ≤C = Concentration in extract was less than or equal to the concentration in the control.
↵4 <LQD = Concentration was less than the lowest quantity determinable.
