Eating habits of 40-year-old women (n=592) were evaluated in the study. The women were participants of the programme “Prophylaxis of cardiovascular diseases in the population of 40-year-old citizens of Wrocław” carried out under the auspices of the Health Department of the City Office of Wrocław. In the study, use was made of a 24-h recall method and history of nutrition that included, among other things, average daily number of meals, frequency of meal consumption and food preferences. The examined women were also subjected to analyses of concentrations of total cholesterol, HDL cholesterol fraction and blood glucose as well as measurements of blood pressure and calculations of Body Mass Index (BMI). The study demonstrated the presence of overweight in 27% of the women examined, obesity in 10% of the women, elevated blood level of total cholesterol in 51.7% of the women, elevated blood glucose level in 17% of the women, and elevated systolic blood pressure in 15% of the women. The statistical analysis indicated a significant, unfavourable effect of BMI index on blood pressure and some lipid indices. In the group of women examined (n=592), the risk of cardiovascular disease was estimated in a 10-year period of observations based on Framingham Heart Study criteria. A high risk, i.e. 11–30%, was demonstrated for 25 women.
Background. Changes in the economic and political system that took place in Poland in recent decades had a significant impact on lifestyles of different social groups, especially in youngsters as vulnerable and open to all novelty and changes. Objective. The aim of this study was to evaluate the healthy or non-healthy behaviours including physical activity, diet, time devoted for sleeping, leisure, stress and the use of drugs by students of four universities in Wroclaw. Material and Methods. The study involved 604 students (305 women and 299 men) from four universities in Wroclaw: University of Wroclaw - 25.0%, Wroclaw University of Technology - 24.5%, University School of Physical Education (AWF) - 25.2% and Wroclaw Medical University - 25.3%. A questionnaire developed for this study was used. The questions were both open and closed, one or multiple answers could be matched. The questions related to: physical activity, nutrition, time devoted for sleeping, leisure, stress and stimulants. Results. On the basis of the results it was found that students mostly reported an average level of physical activity. The highest level of physical activity was presented by students of the University School of Physical Education and the lowest by students of the University of Wroclaw. Just one in ten students consumed meals on a regular basis, including one in five studying in the AWF. Almost half of the respondents (48.7%) spent 5-7 hours sleeping. Every tenth student slept less than five hours. Most respondents preferred passive forms of recreation, only one in three practiced sports in their spare time (usually students of the AWF). Every fourth student declared smoking, and more than 90% consumed alcohol. Conclusions. Lifestyle of majority of the students surveyed did not follow the recommendations of preventive care. The need for more efficient education of students is obvious, which will lead to the future positive changes in their lifestyle, reducing the risk of lifestyle diseases.
Empirical drop size distribution data are presented in this paper. Study site was located in Wroclaw city (SE Poland). Disdrometric measurements were been carried out with use of laser monitoring system during single rainstorm on 09 June 2007. Empirical natural rainfall drops size distribution was described by a classical gamma function. Relationship between the drop diameters and its fall velocity for the natural rainfall is also studied with use of new technique based on the joint distribution function.
In 1998–2001, 2025 trees-of-heaven were recorded in 647 locations in Wrocław, Lower Silesia, Poland. They grew in a variety of habitats. Most were found in lowor high-density residential areas, commercial areas, and in city’s parks. These habitats were moderately to highly transformed and classified as euhemerobic, mainly β-euhemerobic. The mean level of their hemeroby was 61. This is probably an optimum level of hemeroby for tree-of-heaven growing in the urban environment. Because the highest concentration of the locations, where tree-of-heaven grows, was found in densely developed areas of the urban thermal island, it is considered a thermophilic species adapted to urban conditions. Tree-of-heaven spreads largely spontaneously. It is a pioneer species colonising habitats unsuitable for other trees. Therefore, it is recommended for planting in urban areas, especially those situated in western Poland.
The frequency of applying of cut flowers to decorate graves in thirteen municipal or parish cemeteries in the city of Wrocław were estimated in years 1998-2000. In each cemetery 10 sample places with 50 graves were chosen. The research covered the species which occurred more than twice. It consisted of herbal plants and shrubs. Analysing the frequency of applying of plants, 129 taxa from 43 botanical families were estimated. The greatest number of taxa were used in Summer – 99, the next in Autumn – 61 and Spring – 50. In each cemetery, respectively, the same 20, 14 and 17 taxa were applied. In Spring the most frequently graves were decorated with: Salix caprea, Tulipa sp., Forsythia cultivars, Narcissus cultivars, Dendranthema grandiflora – spray cultivars, in Summer – Dendranthema grandiflora – spray cultivars, Gypsophilla paniculata, Callistephus chinensis, Campanula glomerata, Lilium cultivars, and in Autumn – Dendranthema grandiflora, Dendranthema grandiflora – garden cultivars, Dahlia pinata, Gladiolus cultivars, Crocosmia crocosmiflora.
The aim of the present work was to evaluate the mercury content in hair of inhabitants of Wrocław, in southwestern Poland. On the basis of a questionnaire and analysis of hair by atomic absorption spectroscopy, it was possible to indicate the sources of mercury exposure. The mean mercury level in hair of the whole population (n=321) was 0.203±0.181 mg·kg⁻¹. The content of mercury in hair of subjects who consumed fish exceeded the upper limit of reference value, which was 0.397 mg·kg⁻¹. Subjects who declared consumption of fish, honey, and mouldy cheese, contained statistically more mercury: 60.5%, 35.4%, and 37.8%, respectively, than those who did not eat these types of food. It was noticed that there was no effect from the place of residence, the presence of pollution emitters, gender, age, weight, height, presence of amalgam fillings, hair dyeing, and smoking cigarettes on mercury content in hair.
Past 44 years, Achillea crithmifolia Waldst. & Kit. has been found in a south part of Wrocław, but in other place than formerly.
Our research was designed to analyze the variability in PM10 concentrations in the Wrocław area from January 2008 to February 2010, and to relate the findings to the existing meteorological and terrain conditions. To this end, five measurement stations were located in places with distinctive environmental features. Stations used the TEOM 1400a gravimetric analyzer and the manual reference method. The distinction between warm and cold seasons also was made based on start and end dates of heating periods. Finally, the thorough analysis of observed fluctuations in PM10 was produced. This includes tabulating the data, establishing a correlation and, most importantly, presenting descriptive statistics. Moreover, the statistical analysis was extended to variability and correlation analysis. The figures revealed that there exists the spatial variation of PM10 concentrations throughout the year, and analysis showed similar dynamics of the PM10 concentrations. The highest annual average PM10 concentration was noted at one of the stations and was associated with numerous exceedings of the limit value. The analyzed stations show a high correlation during the cold period of the year (0.71-0.95). Coefficients were significant at the 0.99 confidence level. The value of coefficient of divergence ranged from 0.053 to 0.613 and indicated the sources of PM10 emission. A positive relationship was observed between PM10 concentration and, e.g., atmospheric pressure (0.40), and in the warm season, average daily air temperature (0.36); but a negative relationship was observed between PM10 concentration and, i.e., the average daily speed of the wind (-0.56), and during the cold period, the average daily air temperature (-0.56). In support of this claim, the following article discusses select examples of the interdependence between terrain characteristics and PM10 variations.
