Opis:
Decisions about how to remediate chemically degraded areas, including those contaminated with heavy metals, should take into account not only the restoration of soil quality but also other factors, such as an ecological risk. The aim of this work was to assess the ecological risk in an area historically contaminated with heavy metals originating from the metallurgical industry and pollution transported from outside the study area, using a multi-stage TRIAD procedure (considering different lines of evidence). This paper presents the results of chemical, ecotoxicological and ecological tests carried out on soils in the Sławków area in the Upper Silesian Industrial Region, one of the most severely polluted regions in Europe, especially contaminated with heavy metals. Conventional risk assessment methods based on determining the level of pollutants in the soil showed high content of heavy metals, especially of Cd, Pb and Zn. This level of pollution requires limiting land use and taking remedial actions. The inclusion of research based on biological methods has significantly expanded the possibilities of an assessment of the actual state of the environment. An environmental risk assessment based on the TRIAD procedure showed that the contamination has potentially fewer negative impacts on the environment and human health than demonstrated by a conventional assessment based on absolute limit values for metals.

Opis:
Fish are a recommended component of the diet, supplying complete proteins, vitamins, mineral salts, and omega-3 fatty acids. The presence of mercury in fish tissue, both freshwater and marine, is the effect of its accumulation in the aquatic environment and depends largely on the concentration of mercury in water as well as food. Most of mercury in fish tissues is present in the form of organic complexes, mainly methylmercury, which is much more toxic than metallic mercury. In organisms of predatory fish, such as shark, tuna, swordfish, or eel, mercury will be present in concentrations higher than in other species of fish. It is not just the result of their nutrition, but is also related to their age, mobility and habitat. In fish living near the bottom of a water body, the concentration of mercury will be much higher. It has to be noted that the ongoing climate change and increase in environmental contamination may significantly raise the bioavailability of mercury and its organic complexes in fish. Fish that are at the end of a food chain may contain such large amounts of mercury in their organisms that it may pose a threat to human health. This problem is particularly concerning people whose diets are based on fishmeat. The aim of the following paper is to present the current state of knowledge on sources of mercury released into aquatic environments and the related threats to human health with regard to fish consumption. The article takes note of the increasing number of incoming alerts under the European Rapid Alert System for Food and Feed (RASFF), regarding the contamination of fish and fish products with mercury.

Opis:
Currently, lignicolous fungi, commonly referred to as polypores, belonging to the division of Basidiomycota (basidiomycetes), are of great interest. Ganoderma lucidum is one of the representatives. They grow and develop in the wood of trees and shrubs, both living and dead ones. These fungi belong to the world’s most valued and sought-after medicinal plants, used as dietary supplements and applied in medicine. Fungal extracts can be used both for the purposes of prevention and treatment of the acute and chronic diseases. Clinical studies have confirmed the unique characteristics of parasitic medicinal fungi: wide possibilities of application, a high supportive and enhancing role taking into account the effects of treatment of various diseases, non-toxicity and a lack of the side effects of use. Triterpenes and immune-active polysaccharides, mainly β-D-glucans and polysaccharide peptides as well as proteins, are of the greatest health-promoting importance. Glucans that have been most widely used in medicine include: lentinan (from Lentinula edodes), krestin (Trametes versicolor), schizophyllan (SPG), isolated from Schizophyllum commune (splitgill). However, not all glucans have anti-cancer properties since this property depends on their water solubility, size and molecular weight, degree of branching and form of occurrence. High-molecular-weight β-glucans, containing mainly β-(1-3) bonds, display the highest anti-cancer activity. These polysaccharides do not induce allergic reactions or side effects in the human body; however, they show cytotoxic effects against neoplastic cells, as confirmed by in vitro and in vivo studies. A bibliometric analysis on Ganoderma lucidum in the period 1995-2021 was completed in the study. The literature review was conducted searching through the PubMed, SCOPUS and Google scholar databases. The criterion of thematic classification was implemented to carry out an analysis of bibliographic data.

Opis:
Exposure to chemical substances at work may result in negative health effects for workers that are classified as occupational diseases after meeting the formal requirements. Objective of the work: to analyse results of inspections by the State Sanitary Inspectorate in the Mazovia Province in years 2012-2019. Materials and methods: Data concerning occupational diseases were obtained within the scope of access to public information from the Provincial Sanitary and Epidemiological Station in Warsaw. The analysis included data on occupational diseases according to disease entities, pathogenic factor, place of work defined according to the Polish Classification of Activity, and occupational exposure to chemical substances. Results: Occupational diseases for which chemical agents constituted an identified aetiological factor during this period of the analysis of the incidence of occupational diseases resulting from occupational exposure to chemical substances among workers employed at employment establishments subject to the official control accounted for 25.9% (445) of all 1717 (100%) diagnosed occupational diseases. The incidence of occupational diseases resulting from exposure to chemical substances has shown an increasing trend since 2017. The main aetiological agent of the diagnosed occupational diseases was asbestos dust, which was responsible for 325 identified cases. Allergenic agents and irritants were the second aetiological causative factor of the diagnosed occupational diseases – 56 cases. Dust containing free crystalline silica was the third aetiological factor causing 47 cases. Conclusions: Understanding the long-term health effects of exposure to chemical substances and application of occupational health and safety regulations requires continuation of official inspections of the working conditions as well as preventive measures aimed at health education of workers, use of protective measures and examination of the work environment.

Purpose: The aim of the article is to demonstrate the influence of errors and performance errors that affect the damage to the concert hall floor. Design/methodology/approach: When the project was launched, cracks appeared which made the floor unsuitable for further use. In order to determine the cause of the damage, the team conducted a detailed structural health analysis. Findings: The documents used for the analysis included the submitted project records, as well as the actual state of the structure. Research limitations/implications: First, the design team checked the design records for the rooms used for statistical calculations. The arrangement of the floor layers, which was not in accordance with the original design documents, overloaded the load-bearing structure of the Ackerman ceiling. Practical implications: Engineers identified other flawed design guidelines that added to the damage. As a solution, the client followed one of the solutions proposed by the original renovation team. Originality/value: Before the commencement of construction works, an analysis of design solutions and executive assumptions is required, as they may affect the previously made elements of the building structure.

Opis:
This paper presents the results of studies concerning the production and characterization of Al-SiC/W and Cu-SiC/W composite materials with a 30% volume fraction of reinforcing phase particles as well as the influence of corrosion and thermal shocks on the properties of selected metal matrix composites. Spark plasma sintering method (SPS) was applied for the purpose of producing these materials. In order to avoid the decomposition of SiC surface, SiC powder was coated with a thin tungsten layer using plasma vapour deposition (PVD) method. The obtained results were analysed by the effect of the corrosion and thermal shocks on materials density, hardness, bending strength, tribological and thermal properties. Qualitative X-ray analysis and observation of microstructure of sample surfaces after corrosion tests and thermal shocks were also conducted. The use of PVD technique allows us to obtain an evenly distributed layer of titanium with a constant thickness of 1.5 µm. It was found that adverse environmental conditions and increased temperature result in a change in the material behaviour in wear tests.
