Abstract:

In order to provide scientific reference for vegetable production structure adjustment to one vegetable production areas in Longgang District, Huludao City, Liaoning province. Heavy metals Hg, Cr, As, Cd, and Pb content in the soil samples and vegetables sampled from this vegetable production areas were determined by using atomic absorption spectrometry. Results showed that, the heavy metals Hg, Cr, As, Cd, and Pb content in soil were 0.42 mg/kg, 52.20 mg/kg, 34.92 mg/kg, 0.93 mg/kg, and 98.49 mg/kg, respectively that meet the requirements of agricultural production; and the heavy metals Hg, Cr, As, Cd, and Pb content in vegetable were 0.92 μg/kg, 120.09 μg/kg, 13.80 μg/kg, 15.65 μg/kg, 94.17 μg/kg, respectively that also meet national health standards requirement. The heavy metal content of cabbage was more than other vegetable. The experiment would provide data support to adjust vegetable production structure.
