Zusammenfassung |
Our study was an attempt to conduct a comprehensive and systematical examination
of the “holiday effect”, defined as the difference in air pollutant concentrations
between holiday and non-holiday periods. This holiday effect can be applied to
other countries with similar national or cultural holidays. Hourly and daily surface
measurements of six major air pollutants from fifty-four air quality monitoring
stations of the Environmental Protection Administration in Taiwan during the Chinese
New Year (CNY) and non-Chinese New Year (NCNY) periods of 1994-2008 were
used.
The air pollutant concentrations were significantly different between holidays (CNY) and
non-holidays (NCNY), in almost all the Taiwan area, except CO in the eastern part which is a
relatively less-developed area. The industrial development of Taiwan extends from
the north to the south; and then from the west to the east, due to the inconvenient
transportation in the east. The difference percentage, defined as the concentration
difference of CNY minus NCNY relative to the NCNY concentration, is highly
related to the degree of industrialization. The difference percentages of NOx, CO,
NMHC, O3, SO2, and PM10 are more in the west than in the east. Over the western
part of Taiwan, the difference percentages of NOx, CO, NMHC and O3 are more
in the north than in the south; that of SO2basically follows a similar trend but is
more in the middle Taiwan, which might be related to emission change of a major
coal-fired power plant. The difference percentage of PM10 over the western Taiwan is
more in the south than in the north, probably due to stronger dust storm impacts
on the northern Taiwan, where the dust storm sometimes occurs to “pollute” the
clean air during the CNY period, and then causes fewer difference percentage. |
