For this reason different doses of ZnCl2 (0, 200, 400 and 600 mg kg-1) and CdCl2, 2½ H2O (0, 9, 18 and 27 mg kg-1) were applied to an uncontaminated slightly acidic clay loam soil from Sate of Mexico, Mexico incubated under ambient temperature and humidity for 90 days. Both the metals were extracted with a DTPA-TEA-CaCl2 mixture after 1, 5, 15, 25, 60 and 90 days and analyzed using atomic absorption spectroscopy. The results showed that DTPA extractable contents of Zn and Cd followed a decreasing trend with increase in incubation time. Maximum contents were found at day 01 in all the treatments. After 15 days of incubation, the variation in extractable contents was non-significant. The rapid adsorption of the metals might be due to elevated clay content (34%) of the incubated soil.]]>Adriano, D.C.,20012nd Edn.,pp: 626-668pp: 626-668Alloway, B.J.,19952nd Edn.,Pages: 368Pages: 368Amaral Sobrinho, N.M.B., A.C.X.
