The STF database is divided in seven files: (1) identification; (2) references; (3) chemical characterization; (4) immobilization; (5) transformation/degradation; (6) toxicity; and (7) bioconcentration. Approximately 400 chemicals are included. The immobilization file includes information concerning partitioning, immobility, and transport of the chemicals in various soils.
