The main aim of this study was an investigation of the influence of selected soil and plant properties on the bioaccessibility of trace elements and hence their potential impacts on human health in urban environments. Two artificial digestion models were used to determine trace element levels passing from soil and plants to man for bioavailability study. Soil and plant samples were collected from various regions of the province of Sakarya, Turkey. Digestive process is started by addition of soil and plant samples to an artificial digestion model based on human physiology. Bioavailability % values are obtained from the ratio of the amount of element passing to human digestion to element content of soil and plants. According to bioavailability % results, element levels passing from soil samples to human digestion were B = Cr = Cu = Fe = Pb = Li < Al < Ni < Co < Ba < Mn < Sr < Cd < Na < Zn < Tl, while element levels passing from plant samples to human digestion were Cu = Fe = Ni = Pb = Tl = Na = Li < Co < Al < Sr < Ba < Mn < Cd < Cr < Zn < B. It was checked whether the results obtained reached harmful levels to human health by examining the literature.
本研究的主要目的是调查特定土壤和植物特性对微量元素生物可及性的影响，以及由此对城市环境中人类健康产生的潜在影响。采用两种人工消化模型来确定从土壤和植物进入人体的微量元素水平，以进行生物有效性研究。土壤和植物样本采集自土耳其萨卡里亚省的不同地区。通过将土壤和植物样本添加到基于人体生理学的人工消化模型中启动消化过程。生物有效性百分比值通过进入人体消化的元素量与土壤和植物中元素含量的比率获得。根据生物有效性百分比结果，从土壤样本进入人体消化的元素水平为B = Cr = Cu = Fe = Pb = Li < Al < Ni < Co < Ba < Mn < Sr < Cd < Na < Zn < Tl，而从植物样本进入人体消化的元素水平为Cu = Fe = Ni = Pb = Tl = Na = Li < Co < Al < Sr < Ba < Mn < Cd < Cr < Zn < B。通过查阅文献检查所得结果是否达到对人类健康有害的水平。
