Abstract

The study was undertaken to determine the effects of various substances (manure, clay, charcoal, zeolite, and calcium oxide) applied to a cobalt-contaminated soil (0, 20, 40, 80, 160 and 320 mg kg⁻¹ of soil) on the content of certain trace elements in spring barley (main crop) and white mustard (after-crop). The effect of cobalt on the contents of the trace elements was ambiguous and was either antagonistic or synergistic in nature, depending on the organ and plant species. Generally, the substances applied to soil reduced the content of most trace elements in above-ground parts of both plants and in the roots of white mustard, in contrast to the roots of spring barley. Of all the substances, calcium oxide had the strongest and generally reducing effect on the content of trace elements in the tested organs of the plants; however, its effect was the weakest in the roots of white mustard.

Statement of Novelty

It is difficult to find in the literature the results of studies into the effect of mineral and other amendments used in our research (manure, clay, charcoal, zeolite, and calcium oxide) on trace elements content in plants if they are used with a view to weakening the effect of cobalt on plants. We think that it is the novelty in the results of environmental sciences. The literature refer to the application of organic matter, bentonite, zeolite and calcium oxide to neutralize other heavy metals. The research was carried out in the two plants system used for phytoremediation with main crop (spring barley—Hordeum vulgare L.) and after-crop (white mustard—Synapis alba L.). The trace elements were analyzed in test plants. The results of the research allowed to select the most effective substance to support the phytoremediation of soil contaminated with cobalt.

摘要

进行了这项研究以确定各种物质（肥料，粘土，木炭，沸石和氧化钙）对钴污染土壤（0、20、40、80、160和320 mg kg ^{-1的影响）的影响。}土）对春季大麦（主季作物）和白芥末（后茬）中某些微量元素的含量的影响。钴对微量元素含量的影响是模棱两可的，本质上是拮抗的或协同的，具体取决于器官和植物的种类。通常，与春季大麦的根相比，施用于土壤的物质减少了植物的地上部分和白芥末的根中大多数微量元素的含量。在所有物质中，氧化钙对植物被测器官中的微量元素含量具有最强的还原作用。但是，其作用在白芥末根中最弱。

新颖性声明

如果从观点出发，很难在文献中找到研究结果以及对我们研究中使用的矿物质和其他改良剂（肥料，粘土，木炭，沸石和氧化钙）对植物中微量元素含量的影响的研究结果。削弱钴对植物的影响。我们认为这是环境科学成果的新颖性。文献提到有机物，膨润土，沸石和氧化钙在中和其他重金属方面的应用。该研究是在两种植物系统中进行的，该系统用于以主要农作物（大麦（大麦）为大麦）和后茬（白芥子为Synapis alba）进行植物修复。L.）。在测试工厂中分析了痕量元素。研究结果允许选择最有效的物质来支持被钴污染的土壤的植物修复。
