In 2018, we participated in the research on the relationship between air pollution and human health in Baoding district carried out by school of city and environment of Peking University. At that time, Baoding was heavily polluted and fixed-point detection was carried out in the block. According to the monitoring environmental data and the distribution of pollution sources, combined with the list of various pollution gas sources and the impact of each gas on human health, the impact of air pollution on human respiratory health was analyzed.
