KAOHSIUNG, Taiwan -- The air quality in southern Taiwan's Kaohsiung City has shown a marked improvement, with the ratio of Pollution Standard Index (PSI) decreasing to a record low of 3.76 percent as of November, the city's Environmental Protection Bureau said yesterday.
The average PSI of the city in 2009 was 4.9 percent — meaning that the PSI exceeded 100, a standard for unacceptable air quality, on only 4.9 percent of the days in the year.
The figure is in stark contrast to highest PSI since records began — 12.48 percent in 1994.
The improvement is a result of a series of air pollution control measures that have helped reduce carbon emissions, said Lee Mu sheng, director-general of the bureau.
For example, he said, the city government has encouraged citizens to use public transport and has conducted thorough inspections to prevent factories, the city's harbor and construction sites from emitting heavy pollutants.
