recently, serious haze weather has appeared in many parts of China, affecting all aspects of people’s lives, and the most serious harm is to human health
induce respiratory diseases. The composition of haze is very complex, there are hundreds of particles in size, these particles through the human breathing, into the respiratory tract, can cause tracheitis, asthma and other respiratory diseases< 1. Lung injury
