Opis:
Background. This paper evaluated Legionella spp. water system contamination in the public facilities. Material and methods. Samples of warm water from the inner water supply system of 41 facilities in years 2009-2013 and 46 facilities in years 2014-2016 were collected for analyses. The facilities included school dormitories, boarding houses, school-education centers, halls of residence, nursery schools, kindergartens, and correctional institutions. Results. The results of research carried out on tap water in public facilities in 2014-2016 showed that in comparison to 2009-2013 the percentage of facilities from group I increased. In group III facilities a decreasing tendency was observed in comparison to research carried out in 2009-2013. Conclusions. The results indicate that it cannot be explicitly ascertained that the eradication methods of L. pneumophila from tap water systems of the analyzed facilities within the studied period were sufficient. Epidemiological analyses of this type should be successively and systematically continued and based of the largest possible number of facilities.
Wprowadzenie. Celem pracy była ocena skażenia systemów wodnych w budynkach użyteczności publicznej przez bakterie Legionella spp. Materiał i metody. Materiałem były próbki wody ciepłej pobrane z wewnętrznej instalacji wodociągowej 41 obiektów w latach 2009-2013 oraz 46 obiektów w latach 2014-2016. Były to: bursy szkolne, internaty, ośrodki szkolno-wychowawcze, domy studenta, żłobki, przedszkola, zakłady karne. Wyniki. Wyniki badań sieci wody użytkowej obiektów użyteczności publicznej w latach 2014-2016 w porównaniu do lat 2009-2013, wykazały, że odsetek obiektów z grupy I wzrósł. W obiektach z grupy III stwierdzono tendencję spadkową w porównaniu do lat 2009-2013. Wnioski. Wyniki badań świadczą, że w analizowanym okresie nie można jednoznacznie stwierdzić czy stosowane metody eradykacji L. pneumophila z systemów wody użytkowej analizowanych obiektów są wystarczające. Tego typu analizy epidemiologiczne należałoby sukcesywnie i systematycznie kontynuować w oparciu o jak największą liczbę obiektów.

Opis:
Heavy metals, which are considered basic industrial and environmental pollutants, pose a threat to the human health if found in food products even in trace amounts. Lead may cause such conditions as functional disorders of the kidneys, liver or the circulatory system. It can also impede the biosynthesis of heme and cause disturbances in the metabo- lism of vitamin D and the following microelements: Fe, Cu, Zn Se and Ca. The aim of the study was to assess the health threat and estimate risks from the presence of Pb in cereal products available in retail shops in the Province of Podlasie. The material consisted of samples of cereal products (flour, groats, bakery products, pasta and rice) taken at random from retail shops in Podlasie in 2004-2005 and 2010-2011. The lead concentration was estimated by using the atomic absorption spectrometry method (AAS). The content of Pb was analyzed depending on a product type and sampling period; the health threat was assessed with reference to the current Polish requirements. The results were statistically analyzed using Statistica 7.1 software, Duncan?s test and Wilcoxon test. The results revealed that the average content of Pb in the examined cereal products did not exceed the norms. During the analyzed period, a decrease in the Pb concentration in cereals was found. This may indicate an improvement in the quality of the environ- ment, which can be measured by the content of Pb in cereal products. At the same time, owing to the significant role of cereal products in human nutrition, the lead content may also serve as a marker of health exposure.

Opis:
The Holocaust - the almost total extermination of European Jews by the Germans during World War II (1939-45) is primarily associated with such German extermination camps as Auschwitz, Bełżec, Majdanek, Sobibór or Treblinka. In addition to these places, Central and Eastern Europe, including territory, within the present Polish borders, is literally dotted with forgotten individual and mass Jewish war graves. These are the graves of Jews who were not sent to the German death camps during the liquidation of the ghettos during Reinhardt’s operation (March 1942 - November 1943), but were murdered during and after the mass extermination. These Jews were buried in nameless graves located in forests, roadside ditches, arable fields, etc. In most cases, their number and exact location are unknown, both for scientists and descendants of victims, although they often exist in the memories of the last living witnesses of the Holocaust and local communities . One of the statutory tasks of the Rabbinical Commission for Jewish cemeteries in Poland is to search for the forgotten graves of Holocaust victims and restore the identity of the murderers who were taken away from them. The Commission, as a religious entity, headed by the Chief Rabbi of Poland, operates in support of the Jewish law - Halacha, whose regulations define the method and methodology of research. Halacha prohibits opening graves and moving the remains of the dead. All investigations specifying the location and size of the graves they must be carried out in a non-invasive manner, without interfering with the soil structure. In this study, the authors present the first results of work on the location of places of execution and mass graves of Jews from World War II, which were carried out using methods respecting the provisions of Jewish law. To locate these places, the following methods are used: the Holocaust witness account, documents from the Institute of National Remembrance, data from laser scanning, GPR measurements, historical and current aerial photographs. The authors will present the methods of their work and the problems they faced during the research.

Opis:
Lead and cadmium pose a serious threat to human health, hence their content in food products is regulated by the EU standards, also binding in Poland. Food contamination with these metals is an etiological factor of civilization diseases. In order to prevent such disorders, it is extremely important to assess the degree of environmental pollution with Pb and Cd, reflected by the level of these metals in food products. Determination of Pb and Cd in food products demonstrates exposure to the toxic effect of these metals and enables evaluation of the threat to human health in a given population. The aim of this study has been to estimate the health threat to the population of the Province of Podlasie ( województwo podlaskie ) due to Pb and Cd contamination of cereal products. The following foodstuffs were analyzed: flour, groats, bread, pasta, rice, bran and soya products. They were collected in 13 administrative districts of the Province of Podlasie while monitoring health quality of food products. Pb and Cd concentrations were determined with the AAS method. The highest Cd level was noted in pastas (0.058±0.0330 mg kg ?1 ) and the highest Pb level was determined in cuscus (0.120±0.0899 mg kg ?1 ). The lowest average Pb concentration was found in groats (0.042±0.0306 mg kg ?1 ) and Cd was the lowest in wholemeal bread (0.016±0.0106 mg kg ?1 ). The average concentrations of Pb and Cd in cereal products did not exceed the permissible limits established by the Minister of Health. The permissible level of Pb was not surpassed until the level of the 90 th percentyl (in couscous and soya products). An average intake of Pb and Cd was within the tolerated amount, corresponding to 10% PTWI and 12% PTWI, respectively. Thus, no threat to the health of the population in Podlasie was detected.

Opis:
Fractionated drilling wastes originating from shale gas exploration in the Baltic Basin in Polish Pomerania were subjected to measurements of mean activity concentrations of naturally occurring radioactive materials (NORMs). X-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses were used to understand the rock structure and texture. The activity concentration of radionuclides in bulk wastes and fractionated samples (latter obtained through a sieve analysis) was analyzed by using a gamma-ray spectrometer. After fractionation, three different size ranges were distinguished. Radiological indices were estimated by comparison with the levels recommended by the International Association of Oil and Gas Producers (OGP) and an equivalent absorbed dose was determined with respect to appropriated disposal of cuttings. The results showed that the drilling cuttings from the Ordovician period have a natural radioactivity level comparable to other rocks with the same lithology (potassium K-40 800-992 Bq/kg and thorium Th-232 23.3-30.8 Bq/kg) and they did not exceed acceptable levels of the total absorbed dose rate. The average absorbed dose rate in outdoor air one meter above the drilling cuttings was 54.1 nGy/h. The relation between particle size and natural radioactivity indicated that the concentration of radionuclides increased as the fractions size decreased.

Opis:
Determination of the pathogenesis and treatment of autism spectrum disorders is one of the major challenges for modern scientists. The main pathogenic factors implicated in these disorders are epigenetic changes caused by environmental factors, which include toxic metals (Cd, Pb, Hg, Mn, Al and As). Also, the nervous system may be affected by the deficiency of microand macroelements (e.g. Zn and Mg). The aim of the work was to analyze the content of particular trace elements in the hair of autistic children. The study material comprised samples of hair collected from both autistic children (study group) and children chosen randomly from general population (control group). The concentrations of Mg, Zn, Cd and Mn were measured by electron scanning microscopy on a Hitachi TM-3000 apparatus, and by X-ray EDS microanalysis. The content of trace elements in hair, mutual interactions between them and their impact on the development of autism in children were evaluated. The results were statistically analyzed with the use of Statistica PL 12.5 software, including the Mann-Whitney U test, Wilcoxon matched-pair test and R-Spearman correlation. According to the study, children diagnosed with autism suffer from both Zn deficiency and toxic metal burden (Cd and Mn). The changes observed in Mg level were statistically insignificant. These abnormalities, as an environmental factor, may play a pivotal role in the pathogenesis of this disease.

Opis:
Introduction: Abdominal aortic aneurysm is a localized widening, located below the renal arteries. The exact etiology is not fully understood. Probably the main role in the formation of abdominal aortic aneurysm plays a correlation between genetic and environmental factors, especially smoking. The disease is primarily diagnosed in older men although in recent years there is an increased prevalence of the disease among women. Untreated abdominal aortic aneurysm increases in size until it ruptures, which often leads to the death of patient. The disease is generally asymptomatic and most of the aneurysms are detected accidentally, eg., during ultrasound examination of the abdominal cavity.Literature search: The PubMed database was searched in order to collect the literature needed to elaborate the aspects of abdominal aortic aneurysm epidemiology. The search was limited to the review of the original publication from the last 10 years.Conclusions: Analysis of the results indicates that the incidence of abdominal aortic aneurysm in Australia is higher than in America and Europe. The total incidence in Western countries is higher than in Asia. AAA incidence in men is higher than in women. Aneurysms having a diameter of 30 to 39 mm were diagnosed more often than aneurysms with a diameter of more than 40 mm.

Opis:
Aluminum (Al) is a widespread element in the earth’s crust. In large quantities, it can be toxic to both plants and herbivores. The aim of the work was to determine the aluminum content in samples of flour, groats and other cereal products available on the retail market in eastern Poland. Al determination was performed in the chemical laboratory of the Biała Podlaska University “EKO-AGRO-TECH”, using a ball mill and a mineralization furnace. The assessment of the content of this element will allow determining whether the aluminum content depends on the type of product, which may be helpful in assessing exposure to aluminum. Samples of flakes and groats were ground in a Fritsh ball mill and dissolved in pure acids, nitrogen and salt (6:1), and mineralized in an Anton Paar furnace. Then, the samples were diluted with distilled water and filtered on paper filters, and the filtrates were subjected to an elemental analysis by atomic emission spectrometer with excitation using an ICP-OES Spectro-blue FME 26 apparatus. The average concentration of aluminum in all tested products does not differ significantly from the average concentrations of this element in individual groups. After averaging in individual product groups, it was found that the average content in all products combined is not statistically different in each of these products. A balanced aluminum concentration was found in the tested cereal products originating from Southern Podlasie (Lubelskie Voivodeship) and from the southern districts of the Podlaskie Voivodeship. It was found that the aluminum concentrations in the tested cereal products did not show statistically significant differences.

Opis:
Background: Legionella spp. have been found in both natural and manmade water systems, coastal waters, thermal waters, moist soils, clays, and near wastewater discharge sites. Aim of the study: This study aims to report a comparative, retrospective epidemiological analysis of water testing study results indicating the presence of Legionella spp. in Poland between 2009-2013 and 2014-2016. This study is a comparative retrospective epidemiological analysis of individual tests for the presence of Legionella spp. in hotels between two different time periods. The two time periods being compared in this study are between 2009-2013 (n=369 hotels) and 2014-2016 (n=174 hotels). Reporting has been performed in accordance with the STROBE checklist. Material and methods: Hot water samples were collected by employees of the Sanitary and Epidemiological Station in Poland as part of routine water quality monitoring. Samples were taken from the water supply systems of 369 hotels, representing 19.59% of total hotels in Poland, from January 2009 until December 2013. Samples were taken from the water supply systems of 174 hotels, representing 7.51% of total hotels in Poland, from January 2014 until December 2016. Results: The percentage of facilities classified as Group I remained comparable for the period between 2009 and 2013 compared to the period between 2014 and 2016. The percentage of facilities classified as Group II, however, showed a clear upward trend between 2014 and 2016 compared to the time period between 2009 and 2013. The percentage of facilities classified as Group III showed a clear downward trend between 2014 and 2016 compared to the time period between 2009 and 2013. Conclusions: The colonization rates observed in this comparative study indicate that the aquatic environment in these facilities requires constant monitoring to lower the risk of legionellosis. The increased colonization of hotel water networks with Legionella spp. is a serious health problem that requires constant monitoring.
