This study investigates the elastic paving material coated on the floor surfaces of athletic facilities. The concentrations of Pb and DEHP(Di-(2-ethylhexyl)phthalate)) in 13 samples obtained from the flooring of an outdoor basketball court were analyzed. Additionally, a risk assessment for the human exposure was conducted. The average concentration of Pb was 2,357.5 mg/kg and ranged from 3.1 mg/kg to 13,465.4 mg/kg. The Pb concentration of 7 out of 13 samples exceeded the KS standard for Pb, which is 90 mg/kg. The largest contribution of DEHP was caused by phthalates, which measured an average concentration of 53,546.6 mg/kg in 13 samples. The hazard quotient (HQ) estimated from the Pb concentrations obtained from 10 samples taken from the surface of the palm after one hour of activity on the basketball court ranged from 0.0001 to 0.0600 and 0.0001 to 0.0550 for teenagers and adults, respectively. An increase in the HQ value was observed when evaluating the upper 95% concentrations, more specifically, 0.0006 to 0.4470 for teenagers and 0.0006 to 0.4090 for adults. The estimated excess cancer risk (ECR) of DEHP was 10-6 and 10-5 for the mean concentration and the upper 95% levels, respectively. These results suggest that there is an inherent health effect when exposed to the elastic paving materials of sports facilities. Therefore, it is necessary to set standards for elastic paving materials with a particular focus on indoor sports facilities where hazardous pollutants can easily accumulate due to the lack of ventilation.
