“…This would be reason for further developing a contaminated area instability-analysis, especially for use within watersheds with an industrial history, and which have a known presence of instable river banks. Examples of regions where the method presented in this paper could prove useful would be some of the industrially exploited regions within the Danube Basin, where contaminants (Literáthy et al 2002 ; Kukucka et al 2015 ), mass movements (Újvári et al 2009 ; Mentes et al 2009 ; Habersack et al 2016 ), and hydroelectric plants are present in various combinations.…”

Industrially utilized river basins are frequently exposed to contaminants originating from polluting activities. However, the physical instability and probability of mass movement mobilization of contaminated soil into rivers have only received little attention. In this study, we present a GIS-based method to produce a regional overview of where and how contaminated areas are potentially exposed to slope instability. A landslide susceptibility-index was used to study the degree and distribution of overlap between contaminated sites and unstable ground. A contaminated area instability hazard classification was produced integrating slope instability and contamination risk classification. Our results indicate that mass movement can be tied mainly to a slope gradient ≥16°, a proximity to the river that is <500 m, a distance of <500 m from roads, concave surface curvature, and sand- and silt soils. Forty-six (22%) of all considered contaminated sites are located within areas with a non-negligible slope instability, of which a majority, 30 sites (14%) are situated on ground with a low or moderate instability. Three sites with a class 2 contamination risk (the 2nd highest class) are located on ground with a very high slope instability.

“…Polychlorinated naphthalenes (PCNs) are a group of aromatic compounds comprising 75 different congeners which persist throughout the environment, despite their production and use as dielectrics, lubricants, or plasticisers being ended . Even recently, they have been detected in urban and rural air, as well as in soil and sediments . PCNs were used as technical mixtures of different congeners (e.g.…”

“…It is well known that the quality and quantity of organic matter is an important factor controlling the concentration of PCDDs/ Fs in bottom sediments (Nie et al 2013;Chen et al 2013;Kukučka et al 2015;Louchouarn et al 2018). The TC content in bottom sediments of the Rybnik Reservoir vary greatly between 2.32 and 174 g kg −1 d.m, with a mean content of 54.5 g kg −1 d.m.…”

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.
