摘要：In this study, the pollution level of Cd, Pb, Zn and Cu was estimated in the samples of soil, water, vegetation and milk collected from the regions of East-Kazakhstan. High concentrations in the soils were measured of Cd in Ayaguz 0.11 mg/kg, of Pb in Urdzhar 19.7 mg/kg, of Zn in Naualy 17.3 mg/kg and Cu in Kabanbai 0.21 mg/kg. These measured data did not exceed the National limits for Cd 0.5 mg/kg, Pb 32.0 mg/kg, Zn 23.0 mg/kg and Cu 3.0 mg/kg. The results of the vegetation analysis showed the presence of high levels of Cd in Ayaguz 0.346 mg/kg, which exceeded the National limit 0.2 mg/kg. Considerable quantity of Pb 1.96 mg/kg, Zn 20.7 mg/kg, Cu 11.1 mg/kg was measured in Naualy. In water samples of Urdzhar region Pb value of 0.039 mg/dm3 was a little higher than the National limit of 0.03 mg/dm3. Zn content in Naualy 1.5 mg/dm3, in Kabanbai 1.25 mg/dm3, in Urdzhar 1.05 mg/dm3 was found to exceed the National limit 1.0 mg/dm3. The level of Pb in milk samples from Urdzhar 0.39 mg/kg, Naualy 0.24 mg/kg and Ayaguz 0.15 mg was found to be higher than the National limit 0.1 mg/kg. Zn concentration exceeded the National limit 5.0 mg/kg in the samples from Kabanbai 6.3 mg/kg and Naualy 5.8 mg/kg.
