The higher accumulation of Mo, W, Cu and Re by soils and organisms in the Baksan River basin owing to the anthropogenic contamination by the former Tyrnyauz W–Mo industrial complex and migration of the metals with natural waters are discovered during biogeochemical studies of W–Mo mining landscapes of the North Caucasus and background territories. The man-made transformed soils of the Baksan River valley and natural waters are enriched in moderately mobile compounds of Mo and other metals. The competitive relationships are found not only between Mo and Cu, but also between Mo and W while assessing the biogenic migration of metals. An increased content of Mo and W is found in the hair coat, blood and milk of farm animals, which is accompanied by changes in the activity of some enzymes.

白山河流域生物地球化学异常的形成

在 W– 的生物地球化学研究中发现，由于前 Tyrnyauz W-Mo 工业综合体的人为污染以及金属与天然水的迁移，Baksan 河流域土壤和生物体对 Mo、W、Cu 和 Re 的积累较高。北高加索和背景地区的莫采矿景观。Baksan 河流域和天然水域的人造转化土壤富含钼和其他金属的中等流动性化合物。在评估金属的生物迁移时，不仅在 Mo 和 Cu 之间发现了竞争关系，而且在 Mo 和 W 之间也发现了竞争关系。在农场动物的毛皮、血液和乳汁中发现钼和钨的含量增加，这伴随着一些酶活性的变化。
