Opis:
Purpose: To evaluate diet, frequency and type of products consumed and offered at school shops. Materials and methods: Studies were conducted in 2014 among 159 pupils of three randomly selected schools in Bialystok (elementary school, middle school, and high school). The original anonymous questionnaire was used as a research tool. Analysis of results depending on age of the respondents was performed using contingency tables and Pearson's chi-squared test. For hypothesis testing evaluation, significance level of 0.05 was assumed. Results: Consumption of four or more meals during the day was declared by more than half of respondents. Three meals were consumed by 41.5% of middle school pupils, 29.8% of primary school children, and 27.1% of secondary school pupils. Percentage of pupils eating meals outside the home increased with age. Elementary school pupils (91.5%) took water to school significantly more often than middle school or high school pupils (64.2% and 54.2% respectively) (p<0.05). The highest percentage of pupils buying fast food at school was elementary school children, while sweet rolls were mostly bought by middle school pupils (75.5%). Elementary school pupils (78%) are provided information on healthy eating habits from family and school, while middle school (66%) and high school pupils (74.6%) receive this information from the media and magazines. Conclusions: Dietary mistakes reported in the group of pupils were more pronounced with age of respondents. Buying at school shops was associated with an increase in the amount of junk food at the cost of nutritious food

Opis:
Biscutella laevigata L. is known as a Tl hyperaccumulator. In Poland Biscutella laevigata occurs in the Tatra Mts (Western Carpathians) and on the calamine waste heap in Bolesław near Olkusz (Silesian Upland). The purpose of this work was to evaluate whether plants of both populations were able to accumulate an elevated amount of thallium in their tissues. The plants were cultivated in calamine soil in a glasshouse for a season and studied at different ages – from 2-week-old seedlings to 10-month-old adults. Additionally, the plants were grown for ten weeks in calamine soil with EDTA to enhance Tl bioavailability. The total content of Tl in plant tissues after digestion was determined by ICP-MS, whereas its distribution in leaves was studied by LA-ICP-MS. Of the total content of Tl in the soil in the range of (15.2–66.7) mg·kgˉ¹d.m., only (1.1–2.1) mg·kgˉ¹d.m. was present in a bioavailable form. The mean content in all the plants grown on the soil without EDTA was 98.5 mg·kgˉ¹d.m. The largest content was found in leaves – 164.9 mg·kgˉ¹d.m. (max. 588.2 mg·kgˉ¹d.m.). In the case of plants grown on the soil enriched with EDTA, the mean content in plants increased to 108.9 mg·kgˉ¹d.m., max. in leaves – 138.4 mg·kgˉ¹d.m. (max. 1100 mg·kgˉ¹d.m.). The translocation factor was 6.1 in the soil and 2.2 in the soil with EDTA; the bioconcentration factor amounted to 10.9 and 5.8, respectively. The plants from both populations did not contain a Tl amount clearly indicating hyperaccumulation (100–500 mg·kgˉ¹d.m.), however, high (>1) translocation and bioconcentration factors suggest such an ability. It is a characteristic species-wide trait; B. laevigata L. is a facultative Tl hyperaccumulator. The largest Tl amount was located at the leaf base, the smallest at its top. Thallium also occurred in trichomes, which was presented for the first time; in this way plants detoxify Tl in the above-ground parts. Leaves were much more hairy in the Bolesław plants. This is an adaptation for growth in the extreme conditions of the zinc-lead waste heap with elevated Tl quantity.
