【摘要】：目的調(diào)查陜西省食品中稀土含量,并評估其對人體健康的影響。方法采用微波消解-電感耦合等離子體質(zhì)譜法測定655份食品中16種稀土元素含量。以GB 2762-2005《食品中污染物限量》為標(biāo)準(zhǔn)對植物性食品中稀土含量進(jìn)行評價(jià)。采用點(diǎn)評估法計(jì)算陜西省居民稀土暴露量及各類食品的稀土貢獻(xiàn)率。結(jié)果陜西省食品中稀土氧化物平均值為0.0951mg/kg(稀土元素平均值0.0761mg/kg),含量范圍在0.0017-2.66mg/kg之間(稀土元素含量范圍0.0014-2.21mg/kg)。不同種類食品中稀土含量有顯著性差異,蔬菜含量最高,水果最低。16種稀土元素在食品中含量差異較大,鈰、釹、鈧、鑭、釔含量高,表現(xiàn)為輕稀土相對富集。蔬菜超標(biāo)率9.15%,糧食、水果均沒有超標(biāo);單因子污染指數(shù)評價(jià)結(jié)果均為安全、清潔。陜西省居民每日通過飲食攝入稀土氧化物的量為91.0μg/d,占ADI的比例為2.17%。蔬菜和糧食對膳食稀土的貢獻(xiàn)率超過了97.49%。結(jié)論陜西省食品中稀土污染程度低,居民通過食品攝入稀土的量是安全的。
[Abstract]:Objective to investigate the content of rare earth elements in food of Shaanxi Province. Methods the contents of 16 rare earth elements in 655 foods were determined by microwave digestion and inductively coupled plasma mass spectrometry. The content of rare earths in Shaanxi Province was evaluated by using point evaluation method. Results the average value of rare earth oxides in food of Shaanxi Province was 0.0951 mg / kg (average value of rare earth element 0.0761mg / kg 路kg ~ (-1)), and the range of the content of rare earth oxide was 0.0761 mg / kg ~ (-1). In the range of 0.0017-2.66 mg / kg (0.0014 ~ 2.21 mg 路kg ~ (-1)) of rare earth elements, there were significant differences in the contents of rare earth elements in different kinds of foods. The vegetable content is the highest, the fruit lowest .16 rare earth elements in the food content difference is big, the cerium, neodymium, scandium, lanthanum, yttrium content is high, the manifestation is the light rare earth element relative enrichment, the vegetable exceeds the standard rate 9.15%, the grain, the fruit does not exceed the standard; The assessment results of single factor pollution index were all safe. Clean. The daily intake of rare earth oxides in Shaanxi Province is 91.0 渭 g / d, accounting for 2.17% of ADI. The contribution rate of vegetable and grain to dietary rare earth is more than 97.49. Conclusion the rare earth pollution in food in Shaanxi Province is low. The amount of rare earth that residents consume through food is safe.
