摘要：

Incubation of soil samples with volatile organic solvents at part-per-thousand (PPT) concentrations leads to the formation of a residual firmly bound fraction that resists evaporation. The concentration of this firmly bound fraction increases with temperature and solvent concentration. Formation of the firmly bound fraction is not greatly effected by the water concentration in the soil. The dynamic head space concentration method (purge and trap) is inadequate for recovery of this firmly bound material.
