Abstract
There is a growing concern in Kuwait for the air quality in the vicinity of
schools. The problem is exacerbated at peak times of congestion, which
adversely affects the traffic flow and air quality. Several primary pollutants have
been observed to be excessive during the peak periods in the country.
Air quality in the vicinity of a government school was assessed in March
2006 for a period of two weeks using an air pollution monitoring station, which
continuously recorded various pollutants’ concentrations and meteorological
variables at five-minute intervals. The results show that during the weekdays, the
measured pollutants emitted from the road traffic next to the selected school,
such as carbon monoxide (CO) and nitrogen dioxide (NO2), were always under
the allowable limits for Kuwaiti air quality standards, except for a single
occurrence of increased NO2 concentration at morning hours. On the other hand,
the values of non-methane hydrocarbon pollutants were found to be several times
above the Kuwaiti air quality standards throughout the investigated period. The
suspended particulates (PM10) concentrations have twice exceeded the limits of
Kuwaiti air quality standards. A traffic counter was used to record the number of
cars in the main road next to the school in fifteen-minute intervals for ten days
during the monitoring period for air quality. Statistical analysis was used in order
to test whether there is any correlation between variations in the CO
concentrations and the traffic frequency during working days’ morning and
afternoon periods. A relation was developed for predicting the necessary
reduction in traffic based on the necessary reduction in CO concentrations.
Keywords: congestion, pollutants, correlation.
