The primary NO x pollutants (mainly NO, as more than 95% of the NO x are emitted as NO) react in the presence of VOCs and sunlight to form a host of secondary pollutants, among them O 3 and other oxidants such as PAN (Finlayson-Pitts and Pitts, 2000).…”

Long term continuous monitoring measurements of urban atmospheric concentrations of O 3 , NO 2 , NO, and SO 2 were performed for the first time in Ciudad Real, a city in central-southern Spain. The measurements were carried out using the differential optical absorption spectroscopy (DOAS) technique, with a commercial system (OPSIS, Lund-Sweden), covering the summer and winter seasons (from 21st July 2000 to 23rd March 2001). Mean levels of O 3 , NO 2 and SO 2 monitored during this period were: 27 μg m −3 , 50 μg m −3 and 7 μg m −3 respectively. The highest hourly averaged value of O 3 (160 μg m −3 ) was measured during the summer period, while NO 2 was enhanced in wintertime (highest values 90 μg m −3 ). In the coldest period, when central heating installations were operating, SO 2 showed maximum levels of 20 μg m −3 . The daily, weekly and seasonal analysis of the data shows that photochemical air pollution dominates in this urban atmosphere and is strongly influenced by levels of motor traffic and domestic heating system emissions. These measurements were compared with other studies in Spain and Europe. Also, the long path averaged DOAS measurements were compared with in situ observations made in Ciudad Real, from 23rd August 2000 to 25th September 2000, using a mobile air pollution control station. All gas concentrations reported in this paper are below the WHO guidelines and the different thresholds introduced by the European Environmental Legislation.

“…This small peak is broader in August indicating a change in the traffic pattern in this vacational month and/or another source of SO 2 . Generally, the levels of SO 2 registered in Ciudad Real during 2000/2001 and 2008 were found to be lower than those encountered in similar studies on other European cities (Gobiet et al, 2000;Vandaele et al, 2002;Kourtidis et al, 2002).…”

“…During the past decade, weekend/weekday differences in levels of air pollutants (especially of O 3 ) have been a subject of research interest (Marr and Harley, 2002;Vandaele et al 2002;Fujita et al 2003, Riga-Karandinos andSaitanis, 2005). Although, weekly changes in the emissions caused by human activities are known to affect the weekly cycle of ambient pollutant concentrations, this emission-concentration relationship, in urban, suburban and rural sites, is not well elucidated as it is reflected in controversial reports (Blier and Winer, 1999;Pun et al 2003).…”

Ambient Air Quality Assessment of Al-Mansoriah Residential Area in the State of Kuwait

Air quality data (ground level ozone (O3 ), non-methane hydrocarbons (NMHC), methane (CH4 ), nitrogen oxide (NO), nitrogen dioxide (NO2 ), carbon monoxide (CO), hydrogen sulfide (H2 S) and sulfur dioxide (SO2 ) of a Kuwaiti residential area, Al-Mansoriah, were analyzed to evaluate and determine: (a) the exceedances of air quality from permissible limits set by the Kuwait Environment Public Authority (KUEPA), (b) the diurnal patterns of air pollutants, (c) the predominant sources of airborne pollutants in the surrounding area, and (d) the ''weekend effect'' on ozone levels. The dataset covered the period of five consecutive years, from January 2000 to December 2004. High levels of ozone were witnessed; recording a number of exceedances. Inhabitants of Al-Mansoriah were exposed, during the period of study, to acute and chronic levels of SO2 . Concerning NMHC, the permissible limit (0.24 ppm- rolling average between 6-9 am), was violated in each of the monitoring years. NO diurnal pattern showed two distinct strong peaks during the months from October to March, in which the low solar radiation does not cause intense photochemical reactions, which lead to NO destruction. A clear H2 S source (considered as a primary one) was witnessed from Kuwait city (Sharq district). The backed up sewage lines and maintenance work coinciding with study period clearly affected Al- Mansoriah. A clear "weekend effect", in terms of difference in levels occurring during midweek and weekends, was ascertained. The analysis suggests that Al-Mansoriah residential area should be considered a NOx sensitive region of Kuwait.
