Investigation and functional comparison of environmental health based on Elmeri index and Geographical Information System (GIS) in large-scale outdoor spaces of Tehran's Enghelab sports complex

The purpose of the current research was to investigate and compare the performance of environmental health based on Elmeri index and Geographical Information System (GIS) in the large-scale open spaces of the Tehran Revolution Sports Complex.

The present study was descriptive, cross-sectional, quantitative and qualitative, which was conducted in order to evaluate environmental health performance using the ELMERI questionnaire method and Geographical Information System (GIS) in Tehran's Engleab sports complex. In Elmeri's method, two components of environmental health, including: cleanliness, order, order and industrial hygiene, were examined and evaluated by HSE experts and researchers in the mentioned spaces. In order to analyze the data collected through GPS device and land use maps of Tehran, GIS 10 tool was used.

In the northern areas of the Revolution sports complex, the concentration of PM10, No. 2 pollutants was higher than other areas. The distribution of air pollution with O3 pollutant was more in the eastern part of the Revolution complex than in other stations, and it was the lowest in the west of the stadium where the golf and tennis courts are located. In Al-Mari's method, the component of cleanliness, order and order of tennis courts was in a good condition with a total index of 83.5% and in the component of industrial hygiene with a total index of 78.8%. In the component of cleanliness, order and order of golf courses, the total index was 82.5%, and in the component of industrial hygiene, the total index of golf courses was 77.6% and it was in good condition.
