Studies have found that vanadium tends to accumulate in the sediments of lakes located in urban areas where fuel oil thermal power plants or boiler houses are present. The highest concentration of vanadium, amounting to 4785 mg/kg, was found in a lake situated less than a kilometer away from a thermal power plant. In contrast, pristine lakes typically have vanadium levels that are consistent with or below the background levels. In certain regions of Karelia, the elevated concentration of vanadium in lake sediments can be attributed to the presence of uranium‑vanadium ores. In urban sediments, vanadium is closely associated with nickel, which can also be released into the environment through the emissions of thermal power plants and boiler houses. It has been observed that vanadium in lakes primarily exists in the solid insoluble fraction, possibly bonded with natural minerals.

研究发现，钒往往会积聚在位于燃油火力发电厂或锅炉房所在城市地区的湖泊沉积物中。在距火力发电厂不到一公里的一个湖泊中发现了钒浓度最高的物质，达 4785 毫克/千克。相比之下，原始湖泊的钒含量通常与背景水平一致或低于背景水平。在卡累利阿的某些地区，湖泊沉积物中钒浓度升高可归因于铀钒矿石的存在。在城市沉积物中，钒与镍密切相关，镍也可以通过火电厂和锅炉房的排放释放到环境中。据观察，湖泊中的钒主要存在于固体不溶部分中，可能与天然矿物结合。
