1980～1982年,对钼矿克山病区(陕西省华县金堆公社境内)水、土、粮中钼含量进行分析,并与非病区比较。共测定水97份、土28份、粮58份。 钼矿克山病区外环境并不缺钼,水钼含量病区为2.189±1.612μg/L,非病区为2.165±1.139μg/L,差异不明显(P>0.05)。土中有效钼含量病区为1.081±0.663ppm,非病区为0.117±0.055ppm(P<0.01)。豆类是钼的富集作物,钼含最最高,小麦次之,玉米最低。病区小麦、玉米钼含量显著高于非病区(P<0.01),而豆类虽病区高于非病区,但统计学上无明显差异。 水钼含量寺坪组为1.341±0.750μg/L;西坪组为3.632±2.865μg/L;罗涧组为2.019±1.965μg/L三组水钼含量以西坪组最高,罗涧组次之,寺坪组最低,但三组间无明显差异。土壤中有效钼含量三组水平大致相同。病区内不同地点同一品种粮中钼含量水平亦基本相同,渭水系南北水、土、粮中钼含量水平对应比较均大致相同。
From 1980 to 1982, the content of molybdenum in water, soil and grain in Keshan ward (the territory of Jindu commune in Huaxian County, Shaanxi Province) was analyzed and compared with non-ward. A total of 97 measured water, soil 28, grain 58. Molybdenum mine Keshan ward outside the area does not lack molybdenum, water molybdenum content of 2.189 ± 1.612μg / L, non-diseased area of 2.165 ± 1.139μg / L, the difference was not significant (P> 0.05). The available molybdenum content in the soil was 1.081 ± 0.663ppm in the ward and 0.117 ± 0.055ppm in the non-ward (P <0.01). Beans are rich in molybdenum crops, the highest molybdenum, followed by wheat, corn the lowest. The contents of molybdenum in wheat and maize in ward were significantly higher than those in non-ward (P <0.01), while those in legume were higher than those in non-ward, but no statistically significant difference. Molybdenum content of Siping group was 1.341 ± 0.750μg / L; Xiping group was 3.632 ± 2.865μg / L; Luojian group was 2.019 ± 1.965μg / L. The Molybdenum content of the three groups was the highest in Xiping group, followed by Luojian group, The lowest group, but no significant difference between the three groups. The available molybdenum content in the soil is about the same in all three groups. The content of molybdenum in the same variety of grain in different places within the ward was also basically the same. The molybdenum content of the north and south water, soil and grain in the Wei River was almost the same.
