ABSTRACT

The current study aims at forming new prediction models to be employed in the approximating the possible uptake of a range of 10 heavy metals (HMs) (Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb and Zn) by Hordeum vulgare tissues including roots, shoots and grains following its growth in soil amended with sewage sludge (SS) using conditions employed in greenhouses. The present study determined an insignificant difference between the actual and predicted quantities of the HMs in the three tissues using t values. The majority of the predicted quantities of the HMs were acceptable with the exception of Cd in the shoots, Cu in grains and Pb in roots. Consequently, it is possible to use these models in assessing the cultivation of barley plants in soil amended with SS in a safe way, while simultaneously monitoring any potential risks to the health of humans.

摘要

目前的研究旨在形成新的预测模型，用于估计一系列 10 种重金属 (HMs)（Cd、Co、Cr、Cu、Fe、Mn、Mo、Ni、Pb 和 Zn）的可能吸收量：大麦组织，包括根、芽和谷物，在温室中使用的条件下，在用污水污泥 (SS) 修正的土壤中生长。本研究使用t确定了三种组织中 HMs 的实际数量和预测数量之间的微不足道的差异价值观。除了枝条中的镉、谷粒中的铜和根中的铅之外，大多数 HM 的预测量是可以接受的。因此，可以使用这些模型以安全的方式评估用 SS 修正的土壤中大麦植物的种植，同时监测对人类健康的任何潜在风险。
