目的了解北京市部分食品中Pb、Cd、总As、总Hg污染物的污染情况,并对检测结果进行分析。方法按照2014年北京市食品安全风险监测计划对5种食品(猪肝、牛肝、羊肝、羊肾和苹果)中的铅、镉、总砷、总汞进行检测及分析。结果 2014年共检测5种食品210件样品,铅的检出率为100.0%,羊肝中的铅污染最为严重,合格率仅为64.7%;除苹果中的镉检出率为72.0%外,其余4种食品中的镉检出率均为100.0%;牛肝的总砷检出率最高,其次是猪肝、羊肝、苹果、羊肾,检出率范围为0~50.0%;牛肝、羊肾的总汞检出率为100.0%,羊肝为88.2%,猪肝为82.9%,苹果的总汞检出率最低,为64.0%。结论食品中的铅污染最为严重,相关部门应采取针对性措施,加强对重点食品的监测和管理。
Objective To understand the pollution status of Pb, Cd, total As and total Hg pollutants in some foods in Beijing and to analyze the test results. Methods The contents of lead, cadmium, total arsenic and total mercury in five kinds of foodstuffs (pork liver, beef liver, goat liver, sheep kidneys and apple) were detected and analyzed according to the 2014 Beijing food safety risk monitoring plan. Results A total of 210 samples of 5 kinds of food were detected in 2014, the detection rate of lead was 100.0%. The lead pollution in goat liver was the most serious with the passing rate of 64.7%. The detection rate of cadmium in apple was 72.0% The detection rate of cadmium in the other four kinds of food was 100.0%. The detection rate of total arsenic in bovine liver was the highest, followed by that in pig liver, goat liver, apple and sheep kidneys. The detection rate ranged from 0 to 50.0% , Sheep kidney total mercury detection rate of 100.0%, goat liver 88.2%, pig liver 82.9%, apple the lowest total mercury detection rate was 64.0%. Conclusion The lead pollution in food is the most serious, relevant departments should take targeted measures to strengthen the monitoring and management of key foods.
