Analysis of heavy metal in imported Russian food

Objective: The aim was to investigate the pollution of various heavy metals in imported food from Russian.Methods:921 batches samples of 10 kinds imported food from two Russian ports in Heilongjiang Province were analyzed according to the national standard method.Results: The results showed that except for water, lead was detected in all of the samples with the detection rate of 93% ( 921 batches) .The detection rate of cadmium was 73.3% ( 258 batches) and the detection rate of arsenic was 39.6% ( 889 batches) . The detection rate of copper was 100% in the red tea and coffee samples. The content of barium exceeded the limit value ( 0.7 mg/L) in 3 batches water samples.Based on the results of the one-sample t-test, lead, arsenic and barium were lower than the limit value in food.The content of the cadmium in the pickled salmon and the content of copper in the coffee were higher than the limit value ( p < 0.05) .Conclusion The contents of heavy metals in most of the imported food from Russia meet the Chinese national limit standard.However, since the contents of detected heavy metals in some of the imported food samples exceeded the limit values, it is necessary to set up a special monitoring program to improve food safety.
