“…Preliminary analysis of the soil used in the experiment revealed the presence of Cd ions at a concentration of 0.43 mg Cd kg -1 DM of soil. The Cd content in the soil was determined according to Baran et al [36]. Based on data published by Tóth et al [37], a dose of 3 mg Cd kg −1 DM was used in the experiment as average soil pollution with Cd ions, while a dose of 5 mg Cd kg −1 DM of soil corresponded to the maximum Cd content determined in Europe.…”

Durum wheat is commonly used in various food industry industries and cultivated worldwide. A serious problem with the species cultivation is its capability to accumulate cadmium (Cd) in the grains. The aim of this study is to investigate whether antioxidant activity may be used as a marker of Cd tolerance in durum wheat. The experiment involved three durum wheat genotypes/lines differing in salt tolerance. The plant response to Cd was appraised based on the activity of ascorbate–glutathione (AsA–GSH) cycle enzymes, ascorbate-to-dehydroascorbate ratio, reduced-to-oxidized glutathione ratio (GSH:GSSG), as well as Cd content in the seeds. The highest activity of dehydroascorbate reductase, monodehydroascorbate reductase, and glutathione reductase was noted in control plants of salt-sensitive cultivar “Tamaroi.” In the presence of Cd, activity of these enzymes was considerably reduced. “Tamaroi” plants demonstrated also the highest Cd content in the grain. In conclusion, we identified the cultivar “Tamaroi” as most susceptible to cadmium, and the level of durum wheat sensitivity to the element can be evaluated based on a significant decrease in the activity of AsA–GSH cycle enzymes and GSH:GSSG ratio.

“…The region in which the reservoir is located is highly industrialised, with mining (hard coal), metallurgical (steel and colour metal mills), construction, transport and chemical industries. Moreover, the Rybnik Reservoir plays an important technological role, as heated waters from the "Rybnik" Power Plant are discharged and sourced from the reservoir (Kostecki et al 2017;Baran et al 2019). The predominant subcatchment, in the southern part of the drainage area, consists of urbanised areas or areas characterised by scattered rural development, as well as agricultural areas.…”

“…Thirtythree samples were taken (30 in the main area and three in the side bays) with an Ekman grab at a sediment depth of 0-15 cm during a research session in July/ August 2017 ( Fig. 1) (Baran et al 2019). The sediment samples were freeze dried and sieved through a 2-mm mesh for analysis of PCDD/F concentration (Urbaniak et al 2014).…”

“…The TOC content was similar to the TC content, with a mean value of 51.6 g kg −1 d.m., but was highly varied (CV = 102%). However, in the sediments, humic substances play an important role in the sorption, distribution and transport of POPs (Staniszewska et al 2016;Baran et al 2019). The content of C ext (∑ Cha + Cfa) in the sediment samples ranged from 1.72 to 35.3 g and Cnh (C nonhydrolysing) from 0.08 to 143 g kg −1 d.m., while the extracted C accounted for 21-72% of the TOC (mean 24%) and Cnh for about 4-86% (mean 76%).…”

“…In the inlet zone of the reservoir, the mixing of the water mass by the water intake and discharge from the power plant is forced by technical processes which oxygenate the water (Kostecki et al 2017). In addition, it is likely that such movements of the heated water mass inside the reservoir accelerated the degradation of organic matter, particularly along the central part of the reservoir (Baran et al 2019).…”

Purpose The purpose of the study was to determine the levels of polychlorinated dibenzo-p-dioxin and polychlorinated dibenzofuran (PCDD/F), two types of persistent organic pollutant (POP), in an urban retention reservoir located in an industrial zone within a coal-mining region. It also assesses the potential ecological risk of the PCDDs/Fs present in bottom sediments and the relationship between their content and the fraction of organic matter. Materials and methods The sediment samples were collected from Rybnik Reservoir, located in the centre of the Rybnik Coal Region, Silesia, one of Poland's major industrial centres. Seventeen PCDD/F congeners in the surface of the sediments were analysed using high-resolution gas chromatography and high-resolution mass spectrometry (HRGC/HRMS). Results and discussion The toxic equivalency (TEQ) of the PCDDs/Fs in the sediments ranged from 1.65 to 32.68 pg TEQ g −1. PCDDs constituted 59-78% of the total PCDDs/Fs, while the PCDFs accounted for 22-41%. The pattern of PCDD/F congeners in the sediments was dominated by OCDD. However, the second-most prevalent constituents were OCDF and ∑HpCDFs in the low TOC sediment (< 10 g TOC kg −1), but HpCDD in the rich TOC samples (> 10 g TOC kg −1). PCDD/F concentrations in the sediment samples were 2-to 38-fold higher than the sediment quality guidelines limit, indicating high ecological risk potential. Although a considerable proportion of PCDDs/Fs in the bottom sediments from the Rybnik Reservoir were derived from combustion processes, they were also obtained via transport, wastewater discharge, high-temperature processes and thermal electricity generation. The PCDD/F concentrations were significantly correlated with all fractions of organic matter; however, the strongest correlation coefficients were found between PCDDs/Fs and humic substances. Besides organic matter, the proportions of silt/clay fractions within sediments played an important role in the transport of PCDDs/Fs in bottom sediments. Conclusions The silt/clay fraction of the bottom sediments plays a dominant role in the movement of PCDDs/Fs, while the organic matter fraction affects their sorption. The results indicate that the environmental behaviour of PCDDs/Fs is affected by the quantity and quality of organic matter and the texture of sediments.

Toxicity studies on sediments near hydropower plants on the Ślęza and Bystrzyca rivers, Poland, to establish their potential for use for soil enrichment

The aim of this study is to analyze the toxicity of the sediments accumulated in the vicinity of hydropower plants (HPs) on the Ślęza and Bystrzyca rivers in Poland and the possibility of using these sediments for soil enrichment purposes. Thus far, there has been little comprehensive research related to the analysis of the impact of HPs on the properties of sediments. The analysis of the granulometric composition, physicochemical properties, heavy metals (HMs) content in sediments, and the growth of three plant species was carried out, including toxicity (HMs) and germination indices (plants). Most parameters were significant between the points upstream and downstream of the analyzed HPs. It has been shown that the most dangerous toxic factor is the high concentrations of Cu, Ni, and Zn in the sediments upstream of the HP on the Ślęza. In most cases, the HMs content was observed to decrease downstream of the HPs (e.g., Cu in Ślęza River: average of 13.44-times), a result of changes in the particle size composition and accumulation of sediments at the site of the dam wall.Typically, the sediments tested stimulated growth in the plant species studied in comparison with the control groups (e.g., germination index for Sorghum saccharatum, Bystrzyca: 273.5% downstream of HPs). The C:N ratio increased downstream of the HPs by an average of 37.11% for the Ślęza River and 10.88% for the Bystrzyca River.The requirements for composting material were not met; however, the sediment could be used to enrich soils with an excessively wide C:N ratio.
