Introduction And Objective: The male reproductive system constitutes a set of tissues which are particularly sensitive to external factors. The aim of the study was to analyze the relationship between background radioactivity and the quality of the semen of the men who have reported to the infertility treatment facility in 2000-2016 in the Lublin region of eastern Poland.
Material And Methods: The radioactivity of the ground-level air layer obtained from the Institute of Meteorology and Water Management in Włodawa in the Lublin region was analysed. 4,250 spermiograms of patients who reported to the treatment facility for the first time due to infertility were analysed and correlated to background radioactivity in the Lublin region in 2000-2016.
Results: A long-term decrease in the percentage of morphologically normal spermatozoa of the patients was observed (r=-0.970; p<0.001 in 2000-2009 and r=-0.925; p=0.003 in 2010-2016). Men's age correlated negatively with sperm motility (r=-0.164; p=0.009) and morphology (r=-0.186; p=0.009). The percentage of spermatozoa with normal morphology was lowered by beta-isotopes of artificial origin in the air in 2000-2009 (r=-0.655; p=0.040) and by the exposure to gamma radiation of the ground-level atmosphere in 2010-2016 (r=-0.676; p=0.048). The percentage of sperm vitality was lowered by gamma radiation in the atmosphere (r=-0.636; p=0.006), but improved by beta isotopes in precipitation (r=0.686; p=0.002) in the whole of the analyzed period.
Conclusions: The percentage of morphologically normal spermatozoa in patients who reported to the infertility treatment depends not only on the age of patient, but also on beta-isotopes of artificial origin and gamma radiation in the atmosphere. Beta isotopes in precipitation affect the improvement of sperm vitality.

The main aim of this work was to study the chemical composition of eighteen ground coffees from different countries and continents with regard to the content of hazardous substances as radioactive elements (K, Ra, Ra, U, U and Cs), metals, including heavy metals, aluminum and some microelements (V, Cr, Mn, Fe, Co, Ni, Cu, Zn) as well as substances that have a positive effect on human health and well-being (polyphenols, proteins, fats and caffeine). The tests were carried out before and after the brewing process using the following techniques: gamma and beta spectrometry, a microwave-induced plasma optical emission spectrometer (MIP-OES), gravimetric method, UV-Vis spectrophotometry as well as thin-layer chromatography. The leaching percentage of certain elements/compounds in coffee infusions was also measured.

Introduction: In 2022-2023, examinations were carried out for the presence of a pathogenic bacterium in ready-to-eat (RTE) vegetable products (sprouts and vegetable mixtures and salads) sold for immediate consumption in retail shops located in Lublin, eastern Poland. The identification of strains were performed according to the Polish Standard and accomplished with the Microgen Listeria-ID System.
Results: A high prevalence of infections was found in the unprocessed sprouts of plants belonging to the cabbage (Brassicaceae) family - kale (30.

Rodents are recognized as reservoirs for , playing a crucial role in maintaining the parasite's presence in the environment. Biomonitoring was conducted to assess the role of sylvatic rodents in maintaining , and to analyse the prevalence and seroprevalence of the parasite in seven wild rodent species. Rodents were collected in an open grassland study site located in northeastern Poland, and dissected.
