The article deals with the current issues of interconnection between public health and the quality of water resources. It was proposed to determine environmental safety areas in the basins of small rivers based on environmental morbidity valuation. Four phases are herewith determined: hazard identification, exposure assessment, environmental mortality rate assessment, decision-making regarding the need for implementation and water protection measures. In order to assess the influence of the state of river quality on the health status of the population in the certain administrative region, the impact factor of recreational water use was introduced. The risks related to organoleptic, sanitary and toxicological properties of water; epidemiological water hazard are considered.

Od 2020 r., kiedy to w Europie zanotowano pierwsze przypadki SARS CoV-2, wiadomo było, że wirus najszybciej będzie rozprzestrzeniał się w dużych skupiskach ludności. Właśnie takimi są zakłady górnicze, gdzie na małej powierzchni współpracuje ze sobą wielu pracowników. Artykuł prezentuje, jak wybrane zakłady górnicze na terenie Śląska poradziły sobie z wzrastającą zachorowalnością na COVID 19 wśród swoich pracowników oraz jakie wprowadziły unowocześnienia, aby zapobiegać rozprzestrzenianiu się wirusa.

Since 2020, when the first cases of SARS-CoV-2 were recorded in Europe, it was known that the virus would spread the fastest in large population centers. This is what mining plants are like, where there are large con-centrations of workers in a small area. This work presents how the chosen mining plants in Silesia coped with the increasing incidence of COVID-19 among their employees and what improvements they introduced to prevent the spread of the virus.

Excessive concentrations of smog toxicants constitute a critical factor influencing the health quality of inhabitants of urban agglomerations. The exposure to elevated concentrations of suspended particulate matter, sulfur dioxide (SO2), nitrogen dioxide (NO2) and carbon monoxide (CO) is associated with an increase of adverse health effects. Prolonged exposure to air pollution, especially from low emission, may be linked not only to a greater risk of developing cancer of the respiratory system, or cardiovascular morbidity but also to the increased frequency of admissions to hospitals and emergency units as well as medical consultations in surgeries and outpatient clinics. The issue was investigated using the city of Cracow as an example. Attempts were made to find the connection between air pollution in the city of Cracow and the frequency of hospitalization and medical consultations of patients (registered in the city) due to lung and bronchial malignancy and cardiac dysrhythmia taking into account the data from the years 2010-2016 submitted by the Malopolska Regional Branch of the National Health Fund.

Przedstawiono wyniki badania zmian gęstości optycznej właściwej dymu w czasie w procesie spalania płomieniowego i bezpłomieniowego klejów akrylowych na bazie akrylanu 2-etyloheksylu, akrylanu butylu oraz kwasu akrylowego nie modyfikowanych oraz modyfikowanych różnymi zawartościami środków ognioochronnych, takich jak grafit ekspandowany (EG) oraz bezhalogenowy uniepalniacz azotowo-fosforowy o nazwie handlowej Ecoret MP. W badaniach stosowano metodę testu jednokomorowego. Efektywne stężenia dodatków środków ogniochronnych określono na podstawie uzyskanych zależności maksymalnej gęstości optycznej właściwej (Dsmax), czasu do osiągnięcia Dsmax oraz gęstości optycznej właściwej w 4. min badania (Ds4min). Najmniejsze wartości Dsmax uzyskiwano w przypadku modyfikacji za pomocą EG, zarówno podczas spalania płomieniowego, jak i bezpłomieniowego. Lepszym supresantem dymu w analizowanych materiałach polimerowych okazał się EG.

This study examines the risk of morbidity for colorectal surgery undergoing patients. The main aim was to identify important risk factors that influence post-operative complications – morbidity, and to create a model to predict possible complications for a patient before surgery. The source data file contains information about 1177 patients who underwent colorectal surgery between 2001 and 2009 at the University Hospital Ostrava, Czech Republic. According to the surgeons’ judgment the following seven independent variables were included in the analysis: Gender, BMI, American Society of Anaesthesiology (ASA) Classification, Stage of Disease, Number of Previous Operations, Surgical Technique and Operation Severity. Discriminant analysis was used for the data evaluation; statistical software SPSS 18 and NCSS 2004 were used for the calculations.

This paper presents the usage of logistic regression for predicting the classification of patients into one of the two groups. Our data come from patients who underwent Phadiatop test examinations and patients who underwent colectomy in the University Hospital of Ostrava. As the predictor variables were chosen personal and family anamneses for Phadiatop test and the physiological and operative scores for colectomy. For Phadiatop test, both of these anamneses were divided into four categories according to severity ranked by doctors. Scores for morbidity were based on the POSSUM system. The psychological score comprises 12 factors and the operative score comprises 6. The categorical dependent variable which we want to predict was Phadiatop test (respectively morbidity). The model for Phadiatop test was tested with the use of a medical database of 1027 clients and morbidity was tested upon a medical database of 364 clients. The developed models predict the right results with 75% probability for Phadiatop test and 70% probability for morbidity in surgery.
