SHANGHAI'S air is lightly polluted today and the local environment watchdog has warned people with respiratory and heart diseases and weak immunization system to stay indoors.

The Shanghai Environmental Monitoring Center released figures of major air pollutants, including PM2.5 particles, which showed air pollution rose quickly in the morning and reached a peak around midday.

The PM2.5 particles measured over 119 micrograms per cubic meter at noon in the city's Putuo District and 125 micrograms per cubic meter at noon in Pudong's Zhangjiang High-tech Park.

China's acceptable daily limit for PM2.5 is 75 micrograms per cubic meter.

PM2.5 can affect air quality and visibility and pose major health risks as the tiny particles are small enough to lodge deep in the lungs and even enter the bloodstream, causing premature death and chronic diseases.
