Chinese National Ambient Air Quality Standards

Chinese National Ambient Air Quality Standards set limits on the concentrations of pollutants in outdoor air to protect public health and the environment. They specify safe levels for pollutants like particulate matter (PM2.5 and PM10), sulfur dioxide, nitrogen dioxide, carbon monoxide, ozone, and formaldehyde. These standards guide government policies and regulations, helping reduce pollution and improve air quality. Compliance ensures cleaner air, lowering health risks such as respiratory and cardiovascular diseases. The standards are regularly updated based on scientific research, aiming to balance economic development with environmental and public health protection.
