2012 - 2019年青海省部分食品中含铝量监测结果分析

目的 基本掌握青海省部分食品中含铝食品添加剂超标污染状况，为有效保障食品安全提供依据。方法 2012 - 2019年采集我省市售7大类食品共860份样品，按照国家统一的方法进行含铝食品添加剂的检测，对比GB2760 - 2011和GB2760 - 2014含铝食品添加剂的使用标准限量前后变化情况，并对检测结果进行分析研究。结果 860份样品铝检出率范围为55%（膨化食品）～100%（海蜇），食品中铝的平均含量为0.064 g/kg。860份样品中含铝食品添加剂添加总体超标率为15.35%，水产品（海蜇）的超标率最高为90.91%、其次是油炸面制品超标率为33.85%，地方食品的超标率为18.67%。结论 我省食品中含铝食品添加剂使用普遍，存在超标问题，应加强食品安全知识及食品安全标准的宣贯、教育，加大市场监管力度，严厉打击超标使用含铝食品添加剂的行为。

Analysis of aluminum contamination exceed standard in Foods with aluminum additives in Qinghai Province in 2012-2019

The aim of this study was to understand the situation of HBV infection in different populations inMengzi city, so as to provide the basis for the prevention and treatment of HBV. Methods The serological detection ofhepatitis B virus was carried out by emulsion technique. The results of five hepatitis B markers in Mengzi city from January1st 2012 to December 31st 2018 were collected, and the HBsAg positive, single HBsAb positive and five all negative indexeswere statistically analyzed. Results The positive rate of HBsAg in 11160 cases was 2.63%. The positive rate of HBsAg from2012 to 2018 showed a downward trend. The positive rate of HBsAg in male was significantly higher than that in female (χ2=3.88, P<0.05). The HBsAg positive rate was the highest in the 45-54 age group and the second high in the 35-44 age group.Among the main modes of HBsAg carrying, the common modes were: HBsAg + HBcAb positive, HBsAg + HBeAb + HBcAbpositive (small three Yang) and HBsAg + HBeAg + HBcAb positive (big three Yang), accounting for 71.33% of the total HBVinfected population. The positive rate of single HBsAb was lower (30.58%), and the lowest was in the 0-4 age group (27.76%).The negative rate of five items was higher (65.62%), and the highest was in the 0-4 age group (73.52%). Conclusion In thefuture, Mengzi city should take the male group as the key group, pay attention to children and young adults, and at the sametime, focus on the major three Yang pattern, the small small three Yang and the all Yin pattern. We should do tertiaryprevention for these key groups, publicize the knowledge of hepatitis B protection and the necessity of vaccination in theearly stage, diagnose the infected persons in the early stage to prevent further liver damage, and treat hepatitis B patientswith antiviral drugs in the early stage
