Radishes were grown in the naturally occurring uranium-containing soils found in the Okanagan Valley of British Columbia. The movement of uranium, molybdenum, copper, and selenium from the soil to the roots and the above-ground plant was investigated. Bioaccumulation was not observed for uranium, copper, and with some exceptions, selenium. Molybdenum bioaccumulates readily in the radish. Uranium and molybdenum uptake appears to be pH-dependent in this plant. Radish roots can be a significant source of uranium and molybdenum. Ingestion of radishes from these soils could easily surpass the maximum daily intake levels of uranium set by the Canadian government. Other crops and possible sources of uranium exposure around these deposits should be investigated.
萝卜种植于不列颠哥伦比亚省奥卡纳根山谷天然存在的含铀土壤中。研究了铀、钼、铜和硒从土壤向萝卜根部及地上部分的转移情况。未观察到铀、铜以及部分情况下的硒的生物累积现象。钼很容易在萝卜中生物累积。在这种植物中,铀和钼的吸收似乎取决于pH值。萝卜根可能是铀和钼的重要来源。食用这些土壤中生长的萝卜很容易超过加拿大政府设定的铀每日最大摄入量。应调查这些矿床周围的其他作物以及可能的铀暴露源。
