目的了解山东省高密市和淄博市淄川区环境和人体硒水平.方法选择高密市李家营镇和淄博市淄川区寨里镇、龙泉镇为调查镇.以调查镇中的自然村为采样单位,每村按方位采2份农户耕作的土壤,每村选3或4户居民,采集居民户自产主食粮食小麦和玉米及居民指甲样品,用2,3-二氨基萘荧光法测定含硒量.结果高密市李家营镇土壤、小麦、玉米、指甲硒水平[(0.054±0.019)、(0.022±0.009)、(0.018±0.007)、(0.365±0.108)mg/kg]明显低于淄川区寨里镇[(0.425±0.080)、(0.130±0.043)、(0.098±0.026)、(0.751±0.134)mg/kg]、龙泉镇[(0.487±0.153)、(0.112±0.030)、(0.097±0.029)、(0.735±0.145)mg/kg;P均<0.01];高密市李家营镇土壤、小麦及玉米硒处于缺乏水平(<0.200、<0.025 mg/kg),指甲硒高于硒缺乏标准(0.200 mg/kg),低于适硒水平(≥0.400 mg/kg);淄川区寨里镇和龙泉镇土壤、小麦与玉米、指甲硒均达到适硒水平(0.200、0.040、0.400 mg/kg).结论高密市李家营镇外环境处于低硒水平;淄川区寨里镇和龙泉镇外环境则处于适硒水平,上述地区人体硒水平与环境硒水平相一致.

Objective To investigate selcnium(Se) levels of environment and human body in Gaomi City and Zichuan District of Shandong. Methods Lijiaying Township in Gaomi City of Weifang City, Zhaili Township and Longquan Township in Zichuan District of Zibo City were selected. Two farming soil samples at different spot, local wheat and corn, residents nail samples from 3 to 4 families were collected in each natural village in the investigated towns. The contents of Se were detected by 2,3-diamino naphthalene fluorescence method. Results Se level of the soil, wheat, corn, and nails in Lijiaying [(0.054 ± 0.019), (0.022 ± 0.009), (0.018 ± 0.007), (0.365 ± 0.108)mg/kg] was significantly lower than that in Zhaili [(0.425 ± 0.080), (0.130 ± 0.043), (0.098 ± 0.026), (0.751 ± 0.134)mg/kg] and Longquan[(0.487 ± 0.153), (0.112 ± 0.030), (0.097 ± 0.029), (0.735 ± 0.145)mg/kg;P < 0.01]. In Lijiaying, Se was deficient in soil, wheat, corn(< 0.200, < 0.025 mg/kg), above Se deficiency diagnosis and below Se-adequate level in the nail, while in Zhaili and Longquan, the Se level in the soil (0.425, 0.487 mg/kg), wheat(0.130, 0.112 mg/kg), corn (0.098, 0.097 mg/kg), nails (0.751, 0.735 mg/kg) was adequate (≥0.400 mg/kg). Conclusions The external environment is Se-deficient in Lijiaying, Se-adequate in Longquan and Zhaili. The selenium level in human body is consistent with the external environment.
