Haze is the most what organ injury? Haze of ankang directly first focused on the respiratory system and cardiovascular damage. Respiratory system and the external environment to touch the most frequently, hundreds of atmospheric particulates can directly enter and adhesion in the human respiratory tract and lung, meanwhile to PM2. 5, the most destructive it as long as 1/28 of a human hair, can adsorption of lead, cadmium, antimony, manganese, strontium, polycyclic aromatic hydrocarbons and other pests, deepen the human alveolar and accumulation, bring harm to the respiratory system and even the whole body.
