“…Interestingly, results presented in this paper show that the investigated soils exhibited higher ecotoxicity towards H. incongruens than for the test plants. These outcomes are in agreement with the results of other research in which higher toxicity of heavy metal-polluted soils was identified towards invertebrates than for plants (Szara et al 2020 ; Wieczorek and Baran 2021 ). The higher sensitivity of H. incongruens results from the fact that this organism is in direct contact with the medium (i.e., soil) and that the main exposure route is the oral route (De Cooman et al 2015 ; Heise et al 2020 ).…”

“…The higher sensitivity of H. incongruens results from the fact that this organism is in direct contact with the medium (i.e., soil) and that the main exposure route is the oral route (De Cooman et al 2015 ; Heise et al 2020 ). Besides, the lower sensitivity of test plants (Phytotoxkit test) may be related to the lower sensitivity of plants towards heavy metals than in the case of invertebrates (Ostracodtoxkit) (Wieczorek and Baran 2021 ). It may result from one of the most important protective mechanisms of plants which is related to efficient metal detoxication in the root cells and thus limited translocation of metals through the xylem to the aboveground parts (Wierzbicka et al 2007 ).…”

Phytoremediation, as a cost-effective, highly efficient, environmentally friendly, and green approach, gained attention to the removal of metals, including heavy metals, from contaminated soils. The toxic nature of heavy metals can have an adverse effect on human health and the ecosystem, and their removal remains a worldwide problem. Therefore, in this study, a field experiment was carried out to evaluate the potential of Miscanthus × giganteus for the removal of ten microelements and heavy metals (Al, Zn, Fe, Pb, Cd, Co, Cr, Cu, Mn, Ni) from contaminated soil in the territory of a Municipal Waste Rendering Plant. Moreover, the effect of the incorporation of soil improver obtained upon composting biodegradable waste as well as the addition of highly contaminated post-industrial soil on the efficiency of phytoremediation and plant growth was described. The soil improver (SK-8) was applied to the soil at a rate of 200 Mg ha−1 and 400 Mg‧ha−1. Meanwhile, in the last object, 100 Mg‧ha−1 of highly contaminated post-industrial soil was added. Herein, the research was aimed at assessing the possibility of phytoextraction of heavy metals from soils with different physicochemical properties. The results showed that plants cultivated in soil with 400 Mg‧ha−1 of soil improver exhibited the highest yield (approximately 85% mass increase compared to the soil without additives). Furthermore, the application of a single dose of SK-8 (200 Mg ha−1) increased the uptake of Al, Fe, Co, Pb, Mn, Ni, and Cd by Miscanthus × giganteus compared to the soil without additives. Additionally, the performed biotests demonstrated no or low toxicity of the investigated soils affecting the test organisms. However, in all experiments, the phytorecovery of the elements did not exceed 1% of the amount introduced to the soil, which may result from a short cultivation period and large doses of SK-8 or highly contaminated post-industrial soil.

“…In addition, biotests assess the total toxicity of all factors (and substances) present in the tested sample, often acting synergistically or antagonistically 41,42 . Such an approach in research assessing the risk associated with using MV is crucial 43 . In this study, in the context of the environmental effects of the presented MV method, their negligible side effect on the ecotoxicity of soils should be considered an important and promising result.…”

Japanese knotweed (Reynoutria japonica Houtt.) is Poland's invasive weed, of no efficient control method. The rhizomes of this species are rich in resveratrol. In this work, we evaluated 1) the effectiveness of electromagnetic microwaves (MV) in destroying Japanese knotweed using an original device HOGWEED (MV of 2450 MHz); 2) the ecotoxic effect of the MV on the soil environment; 3) the resveratrol content in knotweed rhizomes after MV treatment. The field studies were carried out in 2022 in southern Poland. Cut plants were MV treated at times: 5.0–25.0 min. The MV efficiency was checked 10 and 56 days after treatment (DAT). After MV treatment, fresh soil samples were taken to analyze their ecotoxicity. As a result, at 56 DAT, knotweed was controlled if MV was used for at least 20.0 min. The MV did not affect the soil ecotoxicity. The MV-treated soils were classified as non-toxic or low-toxic. To analyze the resveratrol content, healthy knotweed rhizomes were dug out and treated with MV in laboratory at times: 2.5–10.0 min, and analyzed for the resveratrol content in HPLC-MS/MS. In result, the resveratrol in the rhizomes significantly decreased following MV exposure in a time-depending manner.

“…Cd had the highest average PI, indicating that Cd was the main pollutant and posed the higher than Cu ecological risk. Also, Cu, a much smaller percentage of samples showed a higher degree of contamination (Wieczorek & Baran, 2022).…”

Metals can accumulate in agricultural soils, presenting a serious threat to human health; therefore, it is important to analyze the quality of these soils to avoid possible harm related to their contamination in the future. Despite the importance of monitoring arable soil quality, few studies have examined the current state of Cu and Cd soil contamination through analysis of historical data and temporal trends in heavy metal content. Therefore, this study was aimed at analyzing the spatial variability of Cu and Cd content (expressed by toxicity indices) and assessing the level of contamination of arable soils in Poland over the last 25 years (1995–2020). The average Cu content in soil throughout the duration of the study was ~10 mg/kg. The average Cd content increased from 0.7 mg/kg (in 1995) to 3.4 mg/kg (in 2020). The evaluation of Cu and Cd soil contamination showed that soils contaminated with Cd and Cu constituted 1.4% and 2.3% of the total monitoring points, respectively. The geoaccumulation index and pollution index ranged for Cu from −5.23 to 3.09 (mean: −2.50) and from 0.02 to 6.40 (mean: 0.20), and for Cd from −5.23 to 6.92 (mean: −1.67) and from 0.01 to 60.58 (mean: 0.44). The soil was practically uncontaminated with Cu and Cd in 98.77%/98.92% and 93.44%/97.92% of cases, respectively. On a national scale, the contents of Cu and Cd in soils depend on soil properties (pH, C, OM, ST, and CM) to a very small extent. An assessment of the spatial distribution of Cu and Cd concentrations in Polish arable soils indicated regional differences related to the degree of industrialization/urbanization. The obtained results show the impact of human activity on the level of heavy metals present in soils.
