Application of in Vitro Digestion Approach for Estimating Lead Bioaccessibility in Contaminated Soils:Influence of Soil Properties

  • 摘要: 选取22种典型土壤样品,应用2种in vitro(体外模拟)试验方法——SBET法(simple bioaccessibility extraction test,生物有效性简化提取法)和PBET法(physiologically-based extraction test,生物原理提取法),定量阐明土壤性质对Pb的生物可给性的影响. 结果表明:①SBET法中Pb的生物可给性为18.78%~77.08%,平均值为44.14%;PBET法中Pb的生物可给性为0.72%~50.51%,平均值为13.77%. 除赤红壤和贵州黄壤外,其余20种土壤样品均表现为SBET法中Pb的生物可给性显著高于PBET法,并且随着土壤pH的增长,2种方法的差距更加显著. ②逐步回归分析结果表明,在SBET法中,对土壤Pb的生物可给性影响最大的因子是土壤中w(黏粒),其次为pH,二者可以解释69.49%的Pb的生物可给性的变化;在PBET法中,对土壤Pb的生物可给性影响最大的因子是pH,其次为w(黏粒),二者可以解释73.65%的Pb的生物可给性的变化. 研究结果说明,污染土壤中Pb的生物可给性可以根据土壤pH和w(黏粒)进行预测.
