【摘要】：目的了解山東某輕稀土礦區(qū)與非礦區(qū)糧食中稀土元素含量及其健康風(fēng)險(xiǎn)。方法于2014年7—10月,采集調(diào)查區(qū)域內(nèi)村民自己種植的糧食(小麥、玉米和大豆)樣品339份,采用電感藕合等離子體質(zhì)譜儀(ICP-MS)測(cè)定15種稀土元素的含量。結(jié)果礦區(qū)糧食中總稀土元素含量為9.85~4 268.39μg/kg,中位數(shù)為82.47μg/kg;非礦區(qū)糧食中總稀土元素含量為1.55~2 662.31μg/kg,中位數(shù)為54.75μg/kg。礦區(qū)和非礦區(qū)糧食中稀土元素含量差異無統(tǒng)計(jì)學(xué)意義(P0.05)。礦區(qū)和非礦區(qū)均為小麥稀土元素含量最高(128.79μg/kg和85.14μg/kg),玉米最低(44.89μg/kg和37.95μg/kg)。糧食中稀土元素以富集輕稀土元素為特征。通過糧食攝入的稀土元素遠(yuǎn)小于健康指導(dǎo)值。結(jié)論礦區(qū)和非礦區(qū)糧食中稀土元素含量無差異,以輕稀土元素為主,通過小麥、玉米、大豆攝入的稀土元素不會(huì)危害人體健康。
[Abstract]:Objective to investigate the contents of rare earth elements and their health risks in grain in a light rare earth mining area and non-mining area in Shandong province. Methods from July to October 2014, 339 samples of grain (wheat, corn and soybean) planted by villagers in the investigation area were collected and the contents of 15 rare earth elements were determined by inductively coupled plasma mass spectrometer (ICP-MS). Results the content of total rare earth elements in grain was 9.85 ~ 4 268.39 渭 g / kg with a median of 82.47 渭 g / kg, while that in non-mining grain was 1.55 ~ 2 662.31 渭 g / kg, with a median of 54.75 渭 g / kg 路kg ~ (-1). There was no significant difference in the content of rare earth elements in grain between mining area and non-mining area (P 0.05). The content of REE in wheat was the highest (128.79 渭 g/kg and 85.14 渭 g/kg) in both mining and non-mining areas, and the lowest in maize (44.89 渭 g/kg and 37.95 渭 g/kg). Rare earth elements in grain are characterized by enrichment of light rare earth elements. Rare earth elements through food intake are much smaller than the health guidelines. Conclusion there is no difference in the content of rare earth elements in grain between mining area and non-mining area. Light rare earth elements are the main rare earth elements, and the rare earth elements ingested by wheat, corn and soybean are not harmful to human health.
