摘  要:
为紫阳县富硒农产品的开发利用提供理论依据,采用氢化物发生-原子荧光光谱法,对紫阳县3个乡镇生长的农作物硒含量进行测定。结果表明:紫阳县的双安镇、高桥镇和蒿坪镇的农作物均含有天然硒元素,分别为0.37mg/kg、0.23mg/kg和0.21mg/kg,平均硒含量双安镇>高桥镇>蒿坪镇。农作物产品中以玉米的硒含量最高,平均为0.61mg/kg,其次为萝卜和水稻,分别为0.35mg/kg和0.32mg/kg;双安镇的双河口村、蒿坪镇的黄金树村和高桥镇的何家堡村硒含量较高,分别为0.51mg/kg、0.62mg/kg和0.83mg/kg。检测的以上农作物产品97%达陕西省的富硒食品与其相关产品硒含量标准(DB61/T 556—2012)。

摘  要:
To provide theoretical basis for the development and utilization of selenium-enriched agricultural products,the selenium content of crops grown in three towns in Ziyang County was determined by using hydride generation-atomic fluorescence spectrometry.Results:Natural selenium was detected in all the crops grown in Shuang'An Town,Gaoqiao Town and Haoping Town in Ziyang County,respectively 0.37 mg/kg,0.23 mg/kg and 0.21 mg/kg.Selenium content was the highest in corn,0.61 mg/kg on average,average selenium content followed the sequence of Shuang'An Town > Gaoqiao Town > Haoping Town,followed by carrot and rice,respectively 0.35 mg/kg and 0.32 mg/kg.Selenium content was higher in Shuanghekou Village(Shuang'An Town),Huangjinshu Village(Haoping Town)and Hejiabao Village(Gaoqiao Town),respectively 0.51 mg/kg,0.62 mg/kg and 0.83 mg/kg.More than97% agricultural products met the requirements of selenium-enriched standard(DB61/T 556—2012)in Shaanxi Province.
