| Abstract: | According to the method for determination of available forms of heavy metals in soil extracted with DTPA,the amounts of available Pb and Cd in a soil was determined with atomic absorption spectrometer.A control test was simultaneously conducted in several laboratories.It has been indicated that the method was reliable and its precision and criterion error were also in line with the limit of nation criterion. |
