摘要: |
用原子吸收光谱法测定了陕西省部分城市17种蔬菜的152个样品中铅、铬、镉含量。结果表明,蔬菜中铅、铬、镉含量分别为(0.252±0.312),(0.123±0.424)和(0.035±0.039)mg/kg,其中分别有30.3%,1.3%和2.0%的蔬菜样品中铅、铬和镉含量超出了国家卫生标准的允许量,铅是陕西省蔬菜中的主要污染元素。初步摸清了陕西省蔬菜中重金属的污染状况。 |

Abstract: |
Pb, Cr and Cd contents are determ ined by atomic spectrophotometer in 152 samples of 17 kinds of vegetables in some cities of Shaanxi Province.The results show that Pb,Cr and Cd contents in vegetables are (0.252±0.312)mg/kg,(0.123±0.424)mg/kg and (0.035±0.039)mg/kg,30.3%,1.3% and 2.0%,respectively,higher than the permitted level of Pb,Cr and Cd in vegetable samples (Standard of P.R.C GB 14935-94,GB1496-94,GB15201-94).The major pollutant element is Pb in vegetables of Shaanxi Province. |
