“…This technique has many advantages, such as short analysis time, the possibility of simultaneous determination of micro-and macro-components, uncomplicated sample preparation prior to analysis, and, above all, the use of non-toxic and biodegradable reagents and solvents. Isotachophoresis is classified as a "green chemistry" technique, while the precision and accuracy of the results obtained are better compared to traditional methods [107][108][109].…”

Stilbene and its derivatives belong to the group of biologically active compounds. Some derivatives occur naturally in various plant species, while others are obtained by synthesis. Resveratrol is one of the best-known stilbene derivatives. Many stilbene derivatives exhibit antimicrobial, antifungal or anticancer properties. A thorough understanding of the properties of this group of biologically active compounds, and the development of their analytics from various matrices, will allow for a wider range of applications. This information is particularly important in the era of increasing incidence of various diseases hitherto unknown, including COVID-19, which is still present in our population. The purpose of this study was to summarize information on the qualitative and quantitative analysis of stilbene derivatives, their biological activity, potential applications as preservatives, antiseptics and disinfectants, and stability analysis in various matrices. Optimal conditions for the analysis of the stilbene derivatives in question were developed using the isotachophoresis technique.

“…Precipitation and sedimentation are the dominant processes that cause metals to accumulate in bottom sediments. In addition, acid rain causes a sharp drop in the pH of water, which also contributes to a sharp increase in the concentration of metals in the water [33][34][35][36][37][38][39].…”

Due to their toxicity, lack of bioaccumulation and biodegradability, and ease of binding to sediments, heavy metals are considered the main pollutants of rivers. It is, therefore, necessary to control and monitor these pollutants. The present study analyzed the Krzna River, which flows in southeastern Poland and has an outlet to the Bug River. Over much of its length, the Bug River forms Poland’s border with Belarus, while its origin is in Ukraine. The main purpose of the conducted research was a qualitative and quantitative analysis of selected heavy metals, i.e., Ni, Pb, Zn, Cd, and Cu, in bottom sediments and surface waters of the Krzna River. The secondary objectives were to evaluate the level of contamination of the studied matrices and identify the sources of pollution. Eighty samples of water and bottom sediments from the Krzna River were collected for the analysis. Due to the varying distribution of metals under the influence of changes in temperature, precipitation, and humidity, the samples were collected in May and August 2023. The average cadmium content in the sediments studied was the same in both May and August, at 0.6 mg/kg. In contrast, the nickel content of the sediments ranged from 4.6 to 6.1 mg/kg in May and from 4.8 to 6.8 in August. Only nickel and cadmium of the five heavy metals tested were present in amounts exceeding the geochemical background value. Analysis of the results indicates that only a minimal amount of heavy metals remain dissolved in the surface waters, and the remainder contaminates the sediments. The average concentrations of metals in the studied bottom sediments and surface waters were as follows: zinc > lead > nickel > copper > cadmium. The content of metals in the studied sediments was not high, but at the same time, their presence above the geochemical background indicates anthropogenic human activity. Any changes in hydrodynamic conditions and various environmental factors may result in the re-release of heavy metals contained in sediments into surface waters.

The paper presents results of research on the dynamics of changes in the concentration of polycyclic aromatic hydrocarbons in selected lotic water bodies. Samples were collected in four time frames. The research involved surface water samples collected from three rivers in Poland: the Liwiec, the Muchawka and the Bug. The largest of them is the Bug River, which comprises the Liwiec River. The Liwiec River, in turn, encompasses the Muchawka River. The research was carried out using high-performance liquid chromatography (HPLC). The highest mean total polycyclic aromatic hydrocarbon (PAH) concentration of 184.4 ± 58.3 ng dm−3 was obtained in January in water samples collected from the Bug River, while the lowest concentration was recorded in September in water collected from the Muchawka River and was 46.5 ± 18.1 ng dm−3. The obtained values do not exceed the permissible limits for surface water used as a source of drinking water for human consumption in accordance with the regulation of the Minister of Maritime Economy and Inland Navigation of 29 August 2019.
