In the Thu Duc and District 9, the dust density measured surpasses the permissible level, this is mainly due to concentration of many industrial park in the area. The downtown section is no exception particularly the air pollution measured daily at different times shows greater than what is allowable. Effect of air pollutionAcidification:Chemical reactions involving air pollutants can create acidic compounds which can cause harm to vegetation and buildings. Sometimes, when an air pollutants, such as sulfuric acid combines with the water droplets that make up clouds, the water droplets become acidic, forming acid rain. When acid rain falls over an area, it can kill trees and harm animals, fish, and other wildlife. Ground-level ozone:Chemical reactions involving air pollutants create a poisonous gas ozone (O3). Gas Ozone can affect people’s health and can damage vegetation types and some animal life too.Effect to health:Short-term effects include irritation to the eyes, nose and throat, and upper respiratory infections such as bronchitis and pneumonia.
