the effect of ornamental plant species in reducing pollution and purifying the air of sports facilities

Ornamental plants are one of the cheapest and most natural elements for air purification and pollution reduction. the ability of this type of plant species to absorb pollutants and purify the air is undeniable. today, due to industrialization and technological progress, air and environmental pollution has become an important concern in developing countries. the purpose of this research is the effect of ornamental plant species in reducing pollution and purifying the air of sports venues. pollutants that affect the cleanliness of sports places include: benzene, formaldehyde, carbon monoxide, trichloroethylene, ammonia, fume and xylene. eight plant species include: english ivy (hedera helix), aloe vera, devil's ivy (epipremnum aureum), dwarf date palm (phoenix roebelenii), spider plant (chlorphytum comosum), variegated snake plant (sansevieria trifasciata 'laurentii'), boston fern (nephrolepis exaltata 'bostoniensis') and bamboo palm (chamaedorea seifrizii). in order to purify the air and reduce pollution, pollutants were investigated for air purification and reduction of pollutants in this research. according to the results of this research (p lt; 0.05), the necessary information to predict the correlation of air purification with different plant species statistically showed that, based on the model, eight studied plant species have a natural correlation with air purification and sansevieria trifasciata has the greatest effect in reducing pollution and purifying the air of sports venues (beta = 0.348, value = 0.966). the results showed that in any part of the world, the studied plant species are among the most effective species in air purification, so they are suitable for streets, parks and sports places. it is suggested that by using the results of this research, the relevant officials and stakeholders should pay more attention and use the mentioned plants to improve the air quality of the city and sports facilities.
