A method for simultaneous ICP-MS determination of 13 elements in three types of honey from Poland is described. The method was validated, and the uncertainty budget was set up. The results obtained for the relative expanded uncertainties U rel (k = 2) were 15.1% for Al, 18.6% for B, 18.8% for Ba, 7.9% for Ca, 24.4% for Cd, 7.24% for Cu, 7.9% for K, 4.8% for Mg, 8.3% for Mn, 12.7% for Na, 14.9% for Ni, 12.5% for Pb and 13.4% for Zn. Traceability of the measurement results was established based on the use of the corn flour CRM INCT-CF-3 and the apple leaves CRM SRM 1515 and by analyzing spiked samples. Recovery rates between 94% (Zn) and 107% (Na) were found. The detection limits of all elements studied showed the suitability of the procedure for routine analyses. Summarizing it can be concluded that the described analytical procedures to measure the mass fractions of 13 elements in honey samples with established traceability and evaluated uncertainty allow to obtain reliable and internationally comparable results.

The consensus agreement on the quality of health checks aim to enhance informed decision making in clients and protects the affordability of the health care system. The criteria can be developed further into a formal standard and regulation if such authority is warranted.

Mindfulness training program is a type of psychosocial intervention realized, among others, in schools and preschools for students aged from 4 to 18 years and older. The current interest in mindfulness sessions results from: (1) reports of their positive impact on mental health, coping with problems and distribution of attention; (2) the alarming statistics, e.g. WHO, concerning mental health of young people; (3) the need for interventions based on scientific evidence. The main goal of the article is to present mindfulness training programs for children and youth in Europe and North America, focusing on the programs whose effectiveness has been demonstrated in evidence based research. Next goal was to present a review of the main results of meta-analyses of studies on the effects of mindfulness training for children and youth. Finally, the conditions and the possibilities for implementing mindfulness training programs in Polish schools were discussed. It was concluded that the literature review and analysis of research results indicate that there are significant benefits of mindfulness training programs for the students' psychosocial functioning. The mindfulness programs could be effectively implemented within the Polish education system.
