Abstract
|
|
|
The purpose of this study was to investigate air quality in Chungju, Korea, using data obtained with a local air quality
monitoring system. We have utilised cohort studies to investigate the relations between environmental pollution and the
health of residents near large industrial complexes since 2004. This study analyzes the O3, NO2, SO2, CO and PM10 concentration in Chungju from 2002 to 2006. Air pollutants are closely related to the number of manufacturing facilities
and cars, energy utilization and weather conditions. Generally, the diurnal concentration of air pollutants in Chungju
reached the highest level in the morning (about 08:00~) and early evening (about 19:00~). On the other hand, the diurnal
concentration of ozone as recorded gives the highest amount in late afternoon (about 16:00~) and lowest in early morning
(about 08:00~). The concentration of air pollutants in Chungju was highest from winter to spring and lowest during
the summer season. On the other hand, the monthly variation of ozone concentration was greatest in June and smallest
in December. Also the, PM10 concentration posted the highest record in April and the lowest during September. In general,
this study analyzed air pollution changes in Chungju as well as in large scale industrial complex regions within
Korea such as Ulsan, Pohang, Kwangyang, Sihwa · Panwol and Gangneung in Korea. We compared the air quality of
Chungju with those of these cites and found that air pollutants except for CO in Chungju was generally lower than large
industrial complex regions.
