Environmental Monitoring and Assessment of Pollutants in Sports Floors

Nowadays, environmental quality is considered as one of the important parameters in the management of sports spaces. The presence of environmental pollutants can affect the health and efficiency of athletes.The aim of the research is to measure the elements and toxic compounds in the granular flooring used in the sports facilities of Shahrood city.

This research is applied and laboratory method.Heavy elements, monomer, free hydrocarbon and phenolic compounds were measured.To measure the pollutants, ICP-OES model Vista Pro and visible and ultraviolet spectrophotometer model 1240 mini were used.The experiments were repeated three times.Time-weighted average (OEL-TWA) was used to determine the exposure limit.

Free isoprene with 3400 ppm and then dioctyl phthalate with 3280 ppm included the highest amount of compounds.The highest amount of the element belonged to the heavy metal tin with 125,000 ppm and copper with 75,280 ppm, respectively.The results showed that there is a big difference between the standard and the permissible limit of pollutants with the numbers obtained from the tests.2 pollutants arsenic and chromium with "confirmed human carcinogenicity" were identified in the structure of polyurethane flooring.Silica was also identified as "pollutants suspected of carcinogenicity in humans".Lead was also identified as a "confirmed animal carcinogen of unknown relevance to humans" and 12 were assessed as "not classifiable as a human carcinogen".

Some of the elements and compounds in the structure of sports flooring have a range higher than the standards and permissible limits of exposure, which can affect the health of users and, on the other hand, have the possibility of harming the environment.
