Tracing potential soil contamination in the historical Solvay soda ash plant area, Jaworzno, Southern Poland

This study of soil conditions was carried out on 30 meadow soil (podzol) samples from the vicinity of the soda ash heap in Jaworzno, supplemented by analyses of 18 samples of waste deposited on the heap. In all samples, the total content of macroelements (Ca and Na) and heavy metals (Cd, Cr, Ni, Pb and Zn) as well as pH were analysed. The element concentrations were measured using inductively coupled plasma optical emission spectrometry (ICP-OES). The materials examined were neutral to ultra-alkaline. Total accumulations (mg kg−1) of chemical elements in the soil vary from 130.24 to 14076.67 for Ca, 41.40–926.23 for Na, 0.03–3.34 for Cd, 0.94–103.62 for Cr, 0.94–35.89 for Ni, 3.51–76.47 for Pb and 12.05–279.13 for Zn, whereas quantities of the same elements in the waste samples vary from 171705.13 to 360487.94 for Ca, 517.64–3152.82 for Na, 0.2–9.89 for Cd, 1.16–20.40 for Cr, 1.08–9.79 for Ni, 0.1–146.05 for Pb and 10.26–552.35 for Zn. The vertical distribution of the metals was determined in each soil profile. Despite enrichment of heavy metals in the uppermost horizon on the top of the heap, the results lead to the conclusion that the relation of historical production of soda ash in Jaworzno to current contamination of the local soil environment is insignificant

Zanieczyszczenie gleby metalami ciężkimi związane z historycznym hutnictwem cynku w Jaworznie

The initial study of heavy metals (Cr, Cu, Ni and Mn) contamination was carried out on the 22 samples taken from 4 forest soil (podzol) profiles and 5 waste samples taken from 3 points of the historical zinc smelting area in Jaworzno, Southern Poland. XRD and pH analyses on the soil samples were done. The trace element concentrations were measured with the inductively coupled plasma optical emission spectrometry (ICP-OES) after mineralisation in concentrated HNO3 (65 % Suprapur) and HCl (30 % Suprapur). Examined materials were ultra acidic to neutral, mostly very strong acidic. Total accumulations of trace elements in the soil varied from 21.91 to 119.32 mgCr, from 1.4 to 51.16 mgCu, from 2.15 to 36.16 mgNi and from 16.33 to 869.19 mgMn . kg–1. In waste samples quantities of the same elements equalled 45.55–67.38 mgCr, 19.5–244.74 mgCu, 4.96–22.15 mgNi and 30.75–369.11 mgMn . kg–1. Vertical distributions of examined metals were determined in each of soil profiles. The research revealed heavy metal pollution of studied soil. Influence of the historical smelter on the pollution is inferred, which changed soil environment to dangerous for humans, especially due to close proximity of abandoned industry to built-up and recreation areas as well as community gardens

Wroclaw Epidemiological Trial on Diabetes - WET-Diab

WSTĘP. Aktywne poszukiwanie chorych z zaburzeniami gospodarki węglowodanowej stanowi najlepszą metodę zapobiegania późnym powikłaniom tego schorzenia. Celem pracy było określenie czynników ryzyka i częstości cukrzycy typu 2 - cukrzycy znanej i nieznanej w reprezentatywnej grupie mieszkańców Wrocławia. MATERIAŁY I METODY. Badaniu poddano grupę osób w wieku 55-75 lat dobraną drogą losowania warstwowego z bazy PESEL stałych mieszkańców Wrocławia. W pierwszym etapie przeprowadzono ankietę badawczą, analizując pomiary antropometryczne, ciśnienia tętniczego i glikemii we krwi włośniczkowej. Nieprawidłowy wynik glikemii stanowił podstawę zakwalifikowania do drugiego etapu badań, który obejmował glikemię na czczo i doustny test tolerancji glukozy (OGTT, oral glucose tolerance test) u osób z glikemią 5,5-6,7 mmol/l. WYNIKI. Spośród 1500 badanych do drugiego etapu z powodu glikemii powyżej 5,5 mmol/l zakwalifikowano 362 osoby: 216 kobiet i 146 mężczyzn. U 72 osób (19,8%) była to cukrzyca znana. U 10,34% osób potwierdzeniem cukrzycy było stężenie glikemii 2-krotnie przekraczające 7 mmol/l, natomiast na podstawie OGTT cukrzycę rozpoznano u 21,37% osób, nietolerancję glukozy u 37,24%, a nieprawidłową glikemię na czczo u 31,03%. Częstość cukrzycy nieznanej była wyższa niż częstość cukrzycy znanej u badanych w przedziale wiekowym 55–65 lat, natomiast u osób powyżej 65. roku życia większa była częstość cukrzycy znanej. WNIOSKI. Znamiennie częściej stwierdzano cukrzycę nieznaną u kobiet, z tym że wskaźnik masy ciała (BMI, body mass index) w cukrzycy znanej i nieznanej u kobiet nie różnił się istotnie statystycznie, natomiast u mężczyzn cukrzyca nieznana występowała znamiennie częściej, jeśli BMI wynosiło powyżej 30 kg/m2.INTRODUCTION. Active searching for patients with carbohydrate metabolism disorders is the best method for preventing of chronic complications of the disease. The aim of the study was to find risk factors and to estimate prevalence of type 2 diabetes (known and unknown) in Wrocław population. MATERIAL AND METHODS. The study was entered by subjects aged 55-75 years who were randomly chosen (the random number method) from the Wrocław population PESEL database. The first stage consisted of: age, profession, life-style questionnaire, family history, suffered diseases before and the anthropometrical evaluation, blood pressure and fasting capillary glucose level were performed. The patients with incorrect glucose level were included to second stage where fast glucose level and OGTT above 5.5-6.7 mmol/l evaluated. RESULTS. To second stage study 362 (216 women and 146 men) from 1500 subject were included with glycaemia higher than 5.5 mmol/l. The known diabetes was found in 72 persons (19.8%). The diagnosis of diabetes was confirmed because of two examination results higher than 7 mmol/l. Based on OGTT in 21.37% of patients diabetes and in 37.24% impaired glucose tolerance. CONCLUSIONS. Between 55-65 aged patients the prevalence of unknown diabetes was higher than known diabetes while known diabetes in patients older than 65 years was more common. Unknown diabetes was found significantly more often in females. In female with unknown and known diabetes BMI was not significantly different

Thallium and lead variations in a contaminated peatland : a combined isotopic study from a mining/smelting area

Vertical profiles of Tl, Pb and Zn concentrations and Tl and Pb isotopic ratios in a contaminated peatland/fen (Wolbrom, Poland) were studied to address questions regarding (i) potential long-term immobility of Tl in a peat profile, and (ii) a possible link in Tl isotopic signatures between a Tl source and a peat sample. Both prerequisites are required for using peatlands as archives of atmospheric Tl deposition and Tl isotopic ratios as a source proxy. We demonstrate that Tl is an immobile element in peat with a conservative pattern synonymous to that of Pb, and in contrast to Zn. However, the peat Tl record was more affected by geogenic source(s), as inferred from the calculated element enrichments. The finding further implies that Tl was largely absent from the pre-industrial emissions (>~250 years BP). The measured variations in Tl isotopic ratios in respective peat samples suggest a consistency with anthropogenic Tl (ε205Tl between ~ -3 and 4), as well as with background Tl isotopic values in the study area (ε205Tl between ~0 and 1), in line with detected 206Pb/207Pb ratios (1.16–1.19). Therefore, we propose that peatlands can be used for monitoring trends in Tl deposition and that Tl isotopic ratios can serve to distinguish source origin(s). However, given that the studied fen has a particularly complicated geochemistry (attributed to significant environmental changes in its history), it seems that ombrotrophic peatland(s) could be better suited for this type of Tl research

Analysis of Methylglyoxal Concentration in a Group of Patients with Newly Diagnosed Prediabetes

Background: The abnormal serum concentration of methylglyoxal (MGO) has been presented as an indicator of chronic complications in diabetes (DM). Because such complications are also found in pre-DM, we decided to assess the concentration of this compound in individuals with pre-DM, without cardio-vascular diseases. Methods: Frozen samples from individuals newly diagnosed with pre-DM (N = 31) and healthy subjects (N = 11) were prepared and MGO concentration was determined using UHPLC-ESI-QqTOF-MS. Results: Statistical significance was established when the groups were compared for body weight, BMI, fasting glucose level, fatty liver and use of statins but not for the other descriptive parameters. The positive linear correlation showed that the higher HbA1c, the higher MGO concentration (p = 0.01). The values of MGO were within the normal range in both groups (mean value for pre-DM: 135.44 nM (±SD = 32.67) and for the control group: 143.25 nM (±SD = 17.93); p = 0.46 (±95% CI)), with no statistical significance between the groups. Conclusions: We did not confirm the elevated MGO levels in the group of patients with pre-DM. The available data suggests a possible effect of statin intake on MGO levels. This thesis requires confirmation on a larger number of patients with an assessment of MGO levels before and after the introduction of statins

Revealing the Distribution and Bioavailability of Zn, Pb, and Cd in Soil at an Abandoned Zn Processing Site: The Role of Spectrometry Techniques

The focus of this study is the potential geochemical hazard in the soil system affected by historical zinc processing in Jaworzno, southern Poland. Total Zn, Pb, and Cd concentrations for soil samples determined by inductively coupled plasma optical emission spectrometry are reported. The modified three-step BCR sequential extraction procedure for analysis of the soil was successfully applied to obtain critical information on the heavy metal bioavailability and toxic impact on the natural environment. Exchangeable-, reducible-, oxidizable-, and residual fractions obtained using the sequential extraction procedure were separated and the heavy metal contents in each fraction were determined using inductively coupled plasma optical emission spectrometry. The results of the partitioning study provide information on the mobility of heavy metals in the soil profiles. Most of the Zn in the topsoil is related to the exchangeable-, reducible- and organic/oxidizable phases. The Zn fractionation in the whole soil profiles looks slightly different, with depletion of exchangeable- and reducible phases and enrichment of residual- and organic fractions. The greatest amount of Pb is associated with the reducible fraction. Cadmium is mainly found in the exchangeable- and reducible fraction. The spectrometry techniques applied are helpful in metal-level assessment and useful for evaluating the fate of contaminants and their bioavailability in soil systems. They show that 40 years since Zn processing ceased, the total concentrations of Zn, Pb, and Cd in the investigated soils are extremely high. Due to the high proportions of the metals in the easily soluble fraction, it is evident that the Jaworzno area has been strongly affected by the historical zinc industry and that the topsoil is heavily contaminated or even toxic

Assessment of the Condition of Soils before Planned Hard Coal Mining in Southern Poland: A Starting Point for Sustainable Management of Fossil Fuel Resources

In Poland’s largest mining district, the Upper Silesian Coal Basin, there is a growing interest in resource development by small operators. Some concession areas are not yet directly affected by the mining industry. The objects of this research are two such areas and the goal is to determine a load of heavy metals (HM) in soils prior to mining projects and to assess the extent of their contamination at this stage. The metals studied were Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn, while HM contamination was assessed using the Contamination Factor (CF), Contamination Degree (CD), Pollution Load Index (PLI), and Geoaccumulation Index (Igeo). The Ecological Risk Potential Index (ER) and Comprehensive Potential Ecological Risk Index (PERI) were also employed. The pre-mining areas are close to an area where mining was terminated before 2000. For this area, we performed the same set of analyses as for the pre-mining areas studied. HM concentration levels and pollution indices in post-mining areas are significantly higher than in pre-mining areas. The results obtained in the post-mining area give an idea of the expected type and scale of potential threat to soils from mining and can form the basis for monitoring environmental contamination in subsequent investment and operation phases, as well as help develop and implement timely methods to prevent the increase in heavy metal immission to soils during mining activities. We believe that the presented approach of assessing the condition of soils starting at the pre-mining stage can support the sustainable management of energy resources in the cases studied and elsewhere

The Use of Medical and Non-Medical Services by the Elderly during the SARS-CoV-2 Pandemic Differs between General and Specialist Practice: A One-Center Study in Poland

In Poland, there is a lack of documented data on the use of medical and non-medical services by the elderly during the SARS-CoV-2 pandemic. The FIMA questionnaire assesses the use of medical and non-medical services by the elderly. The authors compared the demand for these services during the ongoing pandemic with similar months in 2017. It was confirmed that in the group of 61 surveyed elderly people, the number of individuals who had a medical visit decreased significantly in the three-month period. In the analyzed pandemic period, patients had significantly fewer visits to their general practitioner only. The pandemic had no significant impact on the use of other medical and non-medical services analyzed by FIMA. The limitations may include the small number of respondents, the relatively short period from the beginning of the pandemic covered by the survey, and the nature of the studied patients’ diseases. Further observation of elderly patients’ access to the abovementioned services can improve the efforts of governments and caregivers in this field, which is of particular importance in the group of chronically ill elderly patients
