Determination of Heavy Metals in Vegetables
12 kinds of vegetables were determined the content of mercury, arsenic and plumbum by atomic fluorescence spectrometry. The results of 12 kinds of leafy vegetables, root vegetables and vegetables eggplant were compared with national standards. The results showed that the content of vegetables in all determined vegetables were accord with national standards. The content of mercury in celery, carrots and radish were all light disqualification, they were higher 0.003mg/kg, 0.002 mg / kg and 0.002 mg/kg than national standards, respectively.
