The importance of controlling carbon dioxide, volatile organic compounds, and particulate matter emissions, which are closely linked to a number of harmful effects on human health, is reflected in the potential of global warming, taking into account that CO2, VOCs, and particulate pollution representing indicators of air quality. The aim of this research is to identify three important indicators of air pollution in urban children's playgrounds near the center of Novi Sad, Serbia. Measurement of the pollutant concentration, and the significant parameters of temperature and relative humidity, was carried out on three children's playgrounds. The intention was to detect any variations in air quality at the children's playground over time by measuring the concentration of the pollutants using MANOVA and ANOVA. Our findings indicate that air quality changes to a large extent depending on the factors studied. It is evident that the air quality depends largely on the time of day when the measurements were made. A significant increase in the concentration of pollutants was observed in the second and third time interval due to rising temperatures during the day.
