Monitoring And Analysis Of Lead And Cadmium Contaminants In Food Of Henan Province In 2013

ObjectivesThe purpose of the present study was to investigate the status of lead(Pb) and cadmium(Cd) pollution in food of Henan province in 2013 and determine the possible sources. It can provide scientific evidences for evaluating the effectiveness of food pollution control, food safety risk assessment, risk warning, standard system(revision) and targeted regulatory measures. MethodsWe collected samples from 18 cities of Henan province in 2013. The contents of Pb and Cd were measured according to the national standard. The results were evaluated, statistically analyzed and analyzed according to GB 2762-2012 “National Standard of Food Safety for Pollutants in Foodstuffs”. ResultsIn this investigation, the average value of Pb in food was 0.28 mg/kg and the total violation rate was 2.44%. The violation rates of lead in baked food and dairy products were 16.85% and 9.77%. The average value of cadmium in food was 0.41 mg/kg and the total violation rate was 0.96%. The violation rates of cadmium in edible fungus and vegetables were 4.66% and 1.43%. The lead violation rates of food samples coming from small restaurants and stores around schools were 16.67%, 17.13%. And the Cd violation rates of food samples coming from Roadside stall and internet were 2.57% and 1.83%. ConclusionCompared to the period from 2010 to 2012, the total pollution of lead and cadmium in food of Henan Province during 2013 was significantly improved. However, Pb pollution was more serious than Cd pollution. Among them, bakery and dairy products were particularly polluted; while food in small restaurants and canteen around the schools were in severe cases, Cd contents of food samples coming from Roadside stands and internet were higher.
