Cadmium, lead and zinc were determined in garden soils and vegetable products from private gardens located in a lead/zinc smelter area (Stolberg, Germany). At the same time lead and cadmium were measured in blood and urine samples collected from 90 garden owners. Inspite of extraordinary high levels of cadmium and lead in garden soils and vegetables, blood lead, blood cadmium and urine cadmium levels were not or only slightly elevated in the gardeners when compared to a reference group of subjects from the same area who did not consume home-grown vegetables and fruits. The results show that high levels of pollutants in soil and vegetables are not necessarily associated with an increased burden of pollutants in the human body, and that the transfer of pollutants from soil to humans might have been overestimated in some cases. Moreover, the results underline the preventive character of the guideline values presently applied with respect to the evaluation of soil contaminants.
对位于铅/锌冶炼区(德国施托尔贝格)的私家花园中的花园土壤和蔬菜产品中的镉、铅和锌进行了测定。同时,对90名花园所有者采集的血液和尿液样本中的铅和镉进行了测量。尽管花园土壤和蔬菜中的镉和铅含量极高,但与来自同一地区不食用自家种植蔬菜和水果的对照组相比,园丁的血铅、血镉和尿镉水平并未升高或仅略有升高。结果表明,土壤和蔬菜中的高污染物水平不一定与人体中污染物负担的增加相关,并且在某些情况下,污染物从土壤到人体的转移可能被高估了。此外,结果强调了目前应用的指导值在评估土壤污染物方面的预防性特征。
