Relationship between Suspended Particles in Air and Respiratory Diseases / 环境与健康杂志

ABSTRACT

To discuss the relationship between suspend particles in the air and respiratory diseases. After the fine particle in the air inhaled into the lung, they retained mainly alveolar ducts and alveoli. They induced inflammatory reactive process and produced inflammatory cytokines in the respiratory tract and epithelial hyperplasia, increased the morbidity of respiratory diseases. The polycyclic aromatic hydrocarbons (PAHs) in the air pollutants had carcinogenesis, the mucosa was irritated by it for long-term and might result in canceration and it increased morbidity and mortality of lung cancer.
