Using the DTPA extraction procedure and a graphite furnace atomic absorption spectrophotometer, a practical method for determining soil cadmium levels was developed. Furnace parameters, instrument parameters, solvent dilution factor, and solvent characteristics were determined using experimental field samples and standardized control samples. The DTPA extraction method gave reproducible results and removed approximately 20 to 60% of total soil cadmium.
