THE CHARACTERISTICS OF PM2.5 POLLUTION IN THE ATMOSPHERIC ENVIRONMENT OF JINGZHOU CITY AND ITS IMPACT ON THE HEALTH OF OUTDOOR EXERCISE RESIDENTS

摘要

PM2.5 pollutant is one of the common types of particulate matter in airpollution.PM2.5 has its own unique pollution characteristics, which needs to be studied. Taking the Binhe Community of Jingzhou City as an example, we selected 33 residents as the object, monitored the data before and after 30 days ofexercise of these residents, compared the data and checked the health of the residents. We used MATLAB 20.0B software Stackplot model to per-form the analysis. The testing mainly includes test-ing for vital capacity testing(ml), residual capac-ity/total lung ratio (T value)testing, total carbon di-oxide (TCO2)testing, and carbon dioxide partial pressure(PCO2)testing. The numberofpeople in the range of 0-1000ml and 1000-3000ml increased by 1 person, while the number of people with 3000-5000ml decreased by 2 people, proving that the up-per limit of the population's vital capacity after 30 days of outdoor exercise in the PM2.5 contaminated area was affected. Because of the influence of re-gional factors and nearby industrial development in Hubei,the pollution changes in Jingzhouare suscep tible to climate change. The change trend of PM2.5 pollution characteristics in Jingzhou showed a two-layered trend.
