The bioaccessibility of some elements (As, B, Cd, Cu, Fe, Mn, Ni and Zn) in soils and vegetables was determined using the physiologically based extraction test. An investigation of the geochemical phases of soils through sequential extraction methods followed by ICP-MS detection was also undertaken. Samples were collected from Iskele, Begendikler and Yolbasi villages in the Bigadic region and Yildiz village in the Susurluk region of Balikesir province, Turkey. All of these villages are close to boron mines. Principal component analysis and correlation analysis demonstrated the interrelationship between the bioaccessibility values of these elements in the gastric and intestinal extracts of soils as well as the plant samples grown in those soils and the elements’ concentrations in the different soil fractions. From the bioaccessible concentrations of the elements in the intestinal phases, it was shown that the amounts of As, B, Cu, Mn and Ni in some plant samples were higher than the recommended and tolerable values for human consumption. The bioaccessibilty of these elements in the soils and plants were statistically related with the concentrations of these elements in the labile phases of the soil. The methodology adopted here would be applicable to determining interactions between elements and soil fractions and the interrelationships between bioaccessibility data and soil fractions for any soil samples.

使用基于生理的提取测试确定土壤和蔬菜中某些元素（砷，硼，镉，铜，铁，锰，镍和锌）的生物可及性。还对土壤的地球化学相进行了研究，方法是依次萃取，然后进行ICP-MS检测。样本是从土耳其巴厘克西尔省Bigadic地区的Iskele，Begendikler和Yolbasi村庄以及Susurluk地区的Yildiz村庄收集的。所有这些村庄都靠近硼矿。主成分分析和相关分析表明，这些元素在土壤的胃和肠提取物以及在这些土壤中生长的植物样品的生物可利用性值与不同土壤组分中元素的浓度之间存在相互关系。从肠道阶段中元素的生物可及浓度来看，表明某些植物样品中的As，B，Cu，Mn和Ni含量高于建议的人类食用推荐量和可耐受值。这些元素在土壤和植物中的生物利用度与土壤不稳定相中这些元素的浓度在统计学上相关。此处采用的方法将适用于确定任何土壤样品的元素与土壤组分之间的相互作用以及生物可及性数据与土壤组分之间的相互关系。这些元素在土壤和植物中的生物利用度与土壤不稳定相中这些元素的浓度在统计学上相关。此处采用的方法将适用于确定任何土壤样品的元素与土壤组分之间的相互作用以及生物可及性数据与土壤组分之间的相互关系。这些元素在土壤和植物中的生物利用度与土壤不稳定相中这些元素的浓度在统计学上相关。此处采用的方法将适用于确定任何土壤样品的元素与土壤组分之间的相互作用以及生物可及性数据与土壤组分之间的相互关系。
