The purpose of the research is to measure the toxic elements and compounds in the flooring used in children's playgrounds and sports spaces. This research was applied and laboratory. Heavy elements, free monomer and hydrocarbons and phenolic compounds were measured. Vista Pro model ICP-OES and 1240 mini visible and ultraviolet spectrophotometer were used to measure the pollutants. The experiments were repeated three times and the weighted mean-time index (OEL-TWA) was used to determine the allowable exposure to chemical agents. Magnesium oxide with 6420 ppm had the highest and phosphorus pentaoxide with 60 ppm had the lowest amount of compounds. The highest amount of element belonged to the heavy metal zinc equal to 11080 ppm and the lowest amount belonged to zirconium with 1.50 ppm. Three contaminants of arsenic, uranium and chromium with "proven human carcinogenicity" were identified in the tatami floor structure. Silica has also been identified as a "contaminant suspected of carcinogenicity in humans." Three cases (lead, vanadium, and molybdenum) were identified as "confirmed carcinogenicity for animals with unknown association with humans" and 13 cases were classified as "unclassifiable as a human carcinogen." Some elements and compounds in the structure of sports flooring have a higher suffering than the standards and permissible exposure limits, which can affect the health of users and on the other hand, can be harmful to the environment.

The study is to analyze the perceived fairness and justice of resource allocation to sport event tourism. The analytical research method is comparative causal. The population consisted of 306 experts, chiefs and experts of sport federations of the country. The sample was considered as total. Finally, 252 respondents answered the questionnaires. The rate of return was 82/35%. Data collection was done using Perceived Resource Fairness Questionnaire. The questionnaire consisted of three sections: monetary and financial resources, sport events and camps, products, and television broadcasting. The second part was used here. Descriptive statistics, Kolmogorov-Smirnov test, confirmatory factor analysis, Cronbach's alpha, ANCOVA and Friedman test were used. Data analysis was done by SPSS 22, LISREL 8/8 software. 51.19% of the respondents were male and 48/80% were female.
The results showed that the need for greater international success, equality based on Olympic medalism, and the need for scarce resources are among the most important principles of distribution, and fairness is to be allocated to these camps and sporting events.
