STUDY OF HEAVY METAL CONTENT (Cd, Cu, Pb, Zn) IN FARMYARD OF LAM DONG PROVINCE, VIETNAM

This study aimed to evaluate the content of heavy metals, including cadmium, copper, lead, and zinc in 43 cultivated soil samples collected from Hiep An commune, Duc Trong district, Lam Dong province, Vietnam. The levels of these toxic heavy metals in cultivated soils were evaluated as follows: Cd (0.16 mg/kg to 0.64 mg/kg), Cu (9.0 mg/kg to 41.5 mg/kg), Pb (17.5 mg/kg to 41.0 mg/kg) and Zn (32.1 mg/kg to 90.0 mg/kg). The collected data shows that concentrations of heavy metals in the soil samples were below the allowable limit. Therefore, this area is suited to farm vegetables that are the strength of this region, such as salad, cabbage, tomatoes, cauliflower, kohlrabi. Furthermore, this is a good reference for further studies on the content of trace elements, such as heavy metal toxins in the soil or vegetable/crop grown in the area.
