“…Currently, no quantitative standard of soil enzyme activity has been set to assess the level of heavy metal soil pollution. Generally, high enzyme activity represents good soil quality, while low activity may be related to the toxicity of pollutants to biological processes [8,54]. The urease enzyme (URE) plays an important role in the N cycle [55], it is loosely present in soil and is more often bound to soil organic matter or clay particles.…”

“…ACP activity ranged from 67.7-312.3 (µg P g −1 3 h −1 ), while ALP activity also showed marked differences (56.3-374.0 µg P g −1 3 h −1 ). At the same time, the results of many experimental studies suggest that inhibition of soil enzymes has diminished over time, sudden exposure of microorganisms to heavy metals results in a significant reduction in enzymatic activity, and microorganisms later adapt to polluted environments and thereby help enzymatic activity to recover usually [8,9]. We used a BIOLOG®Eco plate to analyse changes in microbial communities.…”

“…Heavy metals are toxic on soil microorganisms; they inhibit microbial activities and change the diversity of microbial communities [7]. Currently, the enzyme catalase, dehydrogenase, urease, phosphatase, etc., are commonly used as bioindicators [8]. Knowledge of how organisms react to direct anthropogenic effects (contamination, erosion) but also indirect (increase in atmospheric carbon dioxide, etc.)…”

Mining activities have resulted in the existence of dumps, which generally present a perpetual danger of moving and transforming toxic elements. The experimental study was carried out in Nizna Slana (Slovakia) where the main source of emission was the iron-ore mining–processing factory focused on siderite mining. Siderit from Nizna Slana is highly ferrous with an increased level of the Mn content. Among the undesirable impurities on the deposit are mainly As, S, Pb, and Zn. According to the environmental regionalization of the Slovak Republic, the surveyed area represents a region with a slightly disturbed environment. The BIOLOG® Eco plates method was used for ecotoxicological evaluation of contaminated soils, where soil enzymes (acidic and alkaline phosphatase and urease) were also monitored in soils and soil contamination was evaluated according to Hakanson (1980). Based on the results obtained, it can be concluded that the content of Hg, Cd, Cr, Cu, As, Fe, Mn, and Mg is above the toxicity level. As, Fe, Mn, and Mg are the most serious pollutants in the area under investigation, and their pronounced excess indicates contamination, where harmfulness and toxicity can be expected. Based on the evaluation of the contamination factor and the degree of contamination, the soils in the emission field of old mining works are very highly to slightly contaminated with heavy metals. The experimental results in the real environment showed that the activity of soil enzymes showed considerable differences, and, regarding the functional diversity of soil microorganisms, we have not seen significant spatial variability.

“…Soil, water, and air pollution can pose considerable threats for human health and distort the natural balance of ecosystem components [2]. Anthropogenic pressure disrupts biogeochemical cycles and increases the contents of PTE in the environment, which creates serious problems on the local and global scale [3]. Efforts are being made to restore degraded soils and decrease the content of contaminating substances below the established threshold values [4].…”

“…Chalcedonite rock is composed mainly of chalcedony with small amounts of quartz, opal, iron hydroxides, pyrite, manganese compounds, and clay minerals. Chalcedonite is a mesoporous material with a relatively uniform pore structure and a total pore volume of 0.03-0.04 cm 3 •g −1 [18]. Halloysite is composed of nanotubes, and it is characterized by high porosity and specific surface area, high cation exchange capacity, and ease of chemical and mechanical processing.…”

Immobilization of Potentially Toxic Elements (PTE) by Mineral-Based Amendments: Remediation of Contaminated Soils in Post-Industrial Sites

et al. 2020

In many post-industrial sites, the high contents and high mobility of different potentially toxic elements (PTEs) make the soils unsuitable for effective management and use. Therefore, immobilization of PTE seems to be the best remediation option for such areas. In the present study, soil samples were collected in post-industrial areas in Northeastern Poland. The analyzed soil was characterized by especially high contents of Cd (22 mg·kg−1), Pb (13 540 mg·kg−1), and Zn (8433 mg·kg−1). Yellow lupine (Lupinus luteus L.) and two types of mineral-based amendments were used to determine their combined remediation effect on PTE immobilization. A greenhouse pot experiment was conducted to evaluate the influence of chalcedonite and halloysite on plant growth, chlorophyll a fluorescence, the leaf greenness index (SPAD), PTE uptake, and the physicochemical properties and toxicity of soil. The application of chalcedonite resulted in the greatest increase in soil pH, whereas halloysite contributed to the greatest reduction in the contents of Ni, Pb, Zn, and Cr in soil, compared with the control treatment. The addition of halloysite significantly increased plant biomass. The application of mineral-based amendments increased the ratio of variable fluorescence to maximum chlorophyll fluorescence (Fv/Fm) in yellow lupine leaves. The leaf greenness index was highest in plants growing in soil amended with chalcedonite. The results of this study suggest that mineral-based amendments combined with yellow lupine could potentially be used for aided phytostabilization of multi-PTE contaminated soil in a post-industrial area.
