Taipei, Sept. 18 (CNA) Air quality in central and southern Taiwan could worsen in the coming few days as a high pressure system from China moves across the island, the Environmental Protection Administration said Tuesday.
The front might raise the level of ozone concentration to up to 140 parts per billion in these regions, about one to two times higher than normal standards recorded there, the administration said.
"People with respiratory diseases should pay attention, because we will see more similar situations as autumn approaches," said administration official Chu Yu-chi.
The level of pollution is expected to be at its worst around noon due to the effects of stronger sunlight, Chu added, suggesting that people in these areas avoid going outdoors during that time of day.
