Analysis of Heavy Metal Residue in Red Grape of Different Planting Areas
Abstract:
Digestion samples, graphite atomized method and flame atomization method, determinated Cd, Zn, Ni, Cu, Pb, Cr heavy metals in fruits, soil and water of 6 different vineyards of Xinjiang. Analysis and comparison of measurement results with national standards, results showed that: Zn in the fruits of TR2 and Ni in the fruits of TR3 were close to the standard limit value. Zn in the soil of TR2 was close to the standard limit value. Cr in the soil of TR1 was 196.5835 mg/kg, which is greater than 150 mg/kg of II security level standard, so the soil was belong to III security level. Ni in water of TR3 was close to the standard limit value. They should be taken into account.
