Abstract:
Xuanwei district in Yunnan Province of China has pretty high incidence of lung cancer in China, even a- round the world. Studies have shown that there exists a close relationship between lung cancer and local indoor air pollution caused by Bituminous coal. Considering that the indoor air pollution in Xuanwei District is caused by "open fireplace", an indoor air pollution simulation system was designed, and an F344 rats lung damage model was estab- lished for this indoor air pollution fireplace. The model is based on indoor air pollution simulation system with signal multiplexer control and multi-channel acquisition, and mining PID algorithm was used for polynomial fitting to each test point, and a relatively constant PM2. 5 air pollution status was simulated. The results showed that the system could simulate a variety of states of air pollution, provide a new test method for evaluation of human injury caused by indoor air pollution and a new idea for the study of the incidence of lung cancer in Xuanwei district and other places.
