Air Pollution
Another major trigger of emphysema is air pollution. This is more common in developing countries where cooking fires are poorly ventilated and fueled by biomass fuels or coal. In large cities, poor air quality caused by construction dust, exhaust gas, and industrial smoke can also lead to emphysema in many people. The overall effects are quite similar to smoking when these substances would trigger inflammation in your lungs. To reduce the risks, try to cover your face when going out. Also, change the filters in your air conditioner regularly to reduce irritants inside your home. [11]
