摘　　要：目的 调查山东省日照市食源性高碘的危害.方法 2013年,在山东省日照市采集市售常见食品45种,其中水产类食品19种,陆地类食品26种.陆地类食品包括蔬菜22种、蛋1种、肉1种、面食2种.食品碘测定采用《食物中碘的测定砷铈催化分光光度法》（WS 302-2008）.以日照市万平社区长期居住（原高碘地区村民）的当地成年人为调查对象,采用超声法检查甲状腺,根据《地方性甲状腺肿诊断标准》（WS 276-2007）判定肿大率;同时采集尿样,尿碘测定采用《尿中碘的砷铈催化分光光度测定方法》（WS/T 107-2006）.结果 日照市水产类食品含碘量范围为191.7～1 073.3 μg/kg;蔬菜类干样品含碘量范围为1.8 ～ 264.4 μg/kg,蔬菜类湿样品含碘量范围为0.2 ～ 18.0 μg/kg.共抽取当地长期居住的成年居民225人,超声检查甲状腺肿大5人,肿大率为2.22％;采集成年人尿样219份,尿碘含量为2.9 ～ 408.5 μg/L,尿碘中位数为82.8 μg/L;＜100μg/L的138份,占63.0％.结论 日照市不同种类食品含碘量差别很大,但当地居民甲状腺肿大率低于国家标准（＜5％）,成年人尿碘中位数偏低（＜ 100 μg/L）,山东省日照市不存在食源性高碘危害问题.Objective To investigate the hazards of foodborne iodine excess in Rizhao City,Shandong Province.Methods In 2013,45 common foods sold in Rizhao City were sampled,including 19 kinds of sea foods and 26 kinds of inland foods.The latter contained 22 kinds of vegetables,1 kind of egg,1 kind of meat,and 2 kinds of wheaten foods.The ＂Alkaline Ashing-Arsenic Cerium Catalytic Spectrophotometry＂ （WS 302-2008） method was adopted to determine iodine content in food.Besides,thyroid volume of adults lived in Wanping Community of Rizhao City for a long time （residents of original iodine excess villages） was examined by B-ultrasound according to the ＂Diagnostic Criteria for Endemic Goiter＂ （WS 276-2007） and urinary iodine level was also determined according to the ＂Method for Determination of Iodine in Urine by As3＋-Ce4＋ Catalytic Spectrophotometry＂ （WS/T 107-2006）.Results The iodine range of seafood in Rizhao City was from 191.7 to 1 073.3 μg/kg,that of dry vegetables was from 1.8 to 264.4 μg/kg,and for fresh vegetables,from 0.2 to 18.0 μg/kg.Two hundred and twenty-five local longterm adult residents were sampled for testing thyroid volume; 5 persons had enlarged thyroid,and the goiter rate was 2.22%.Totally 219 urinary samples were collected,the median of urinary iodine was 82.8 μg/L,ranged from 2.9 to 408.5 μg/L.One hundred and thirty-eigh urinary samples accunted for 63.0% had a iodine level of lower than 100 μg/L.Conclusions There is a great difference among the iodine contents of different kinds of food,and local residents have a lower goiter rate than the national standard（〈 5%）; moreover,they have a low median of urinary iodine （〈 100 μg/L）.All these results indicate that there is no hazards of foodborne iodine excess in Rizhao City,Shandong Province.
