摘要：

Twenty-six garden soils from Aspen, Colorado, contaminated with old silver mine dumps, were extracted with diethylenetriaminepentaaceticacid (DTPA) and NH4HCO3-DTPA (AB-DTPA). Total soil digests (HNO3-HClO4HF) were carried out on 21 highly contaminated soils. All soil extracts and digests were analyzed for Pb, Cd, and Zn using inductively-coupled plasma atomic emission spectrometry (ICPS). Linear regression equations for DTPA versus AB-DTPA values gave 0.96, 0.99 and 0.99 "r" values for Pb, Cd, and Zn, respectively. Linear regression equations for total Pb, Cd, and Zn levels versus their respective AB-DTPA extractable levels were developed with "r" values of 0.92, 0.93, and 0.89, respectively. It was concluded that AB-DTPA test can be used to screen soils contaminated with the above-mentioned elements.
