Determination of enrichment factor To evaluate the magnitude of contaminants in the soils, EF were computed for each location relative to the abundances of species in source materials to the control/background value and the following equation as proposed by Simex and Helz (1981) [10]; Atgrin et al.
This procedure will result in an enrichment factor of approximately 5x (32); and c) direct centrifugation to the electron microscopic grid with the Beckman Airfuge (Beckman, Palo Alto, CA) EM-90 rotor or A-100 rotor, a procedure that increases sensitivity up to 1,000 fold (40-42).
Given that the concentration of these cells or molecules can be very low compared to other commonly present cell types or molecules, one needs enrichment factors of 1 to 10,000 or 1 to million.
