Nitrate contamination in vegetables from two selected cities in China

Nitrate contamination is one aspect of the safety issue about vegetables. A fast determination method of nitrite was used to access the nitrite contamination level of vegetables sampled form two selected cities in China (Changde and Yangling). The result indicated that the nitrate contamination level of vegetables from Yangling is higher than vegetables form Changde.  The rood vegetables showed the highest contamination level and leaf vegetables and solanaceous vegetables showed lower. Most of test samples contaminated nitrate with level higher than they corresponding MRL. The nitrate contamination situation of vegetables in the select cities is less optimistic,  more  works  were  needed  to  be  done  for  agricultural  management department.
