Pollution takes toll on health in Guangdong

GUANGZHOU: More than 41 percent of people in the Pearl River Delta have felt sick or uncomfortable this year because of the region's heavy pollution, a recent survey found.

Most suffer from diseases like cough, sore throat and upper respiratory infections, or feel agitated, depressed or can't sleep.

Zhou Hongyu, 62, a Guangzhou housewife, said she usually goes to a park near her home every morning to exercise.
