ANALYSIS ON THE IMPACT OF HEAVY LOAD ATHLETES' LUNG FUNCTION UNDER HEAVY HAZE POLLUTION

According to the data of environmental meteorological observation station, the paper consulted the characteristics of air quality and haze pollution in WuHan from January 1, 2015 to January 1, 2019, analyzed the characteristics of air pollutants when the typical heavy haze occurred in WuHan in January 2016 and analyzed the characteristics of lung function of heavy load athletes in heavy haze pollution environment. The results showed that the contents of PM2.5, CO, PM(10 )and NO2 increased in the morning and evening, and decreased in the middle. The highest content of SO2 was at noon, and the highest content of O-3 was at 8 pm. The concentrations of PM2.5, CO, PM10 and SO2 in the industrial area were significantly higher than those in the living area, while the concentration of NO2 in the living area was significantly higher than that in the industrial area, and the concentration of O-3 in the suburb was higher than that in the urban area. In January 2016, there were three severe pollution in WuHan on January 4th, 10th and 18th. The results of cardiopulmonary function test showed that the cardiopulmonary function of high load athletes in heavy haze environment decreased significantly (P<0.05). In short, through this study, we have a clear understanding of the air quality and haze pollution characteristics of WuHan from January 1, 2015 to January 1, 2019, and analyze the haze environment on the cardiopulmonary function injury of heavy load athletes to provide reasonable exercise guidance for the future haze weather.
