“…PC2 (16.3% of the total variance) consist of CO and NO 2 , which points towards vehicular emissions [7], [38]. PC3 (11.7% of total variance) was weighted with only SO 2, which indicates industrial emissions and open burning [39]. A slight difference among the factors distribution was noticed in the principal components for SWM compared to the NEM.…”

Abstract. The aim of this study are (i) to determine the yearly and monsoonal variations of the criteria pollutants in Kuala Terengganu, (ii) identify the influences of the meteorological factors and other minor criteria pollutants that impose on the concentration of the most significant criteria pollutant using Principal Component Analysis (PCA). The hourly data for the criteria pollutants (PM10, CO, O3, NO2, and SO2) and meteorological factors (temperature, relative humidity, windspeed) for the duration of 10 years procured from the Department of Environment, Malaysia were analyzed. PM10 is the only pollutant that frequently recorded concentrations exceeding the MAAQG in the length of the year 2001 to 2010 and the criteria pollutants reported differ significantly between the monsoon seasons. PCA showed that sources contributing to the most significant criteria pollutant (PM10) are meteorological factor influences and industrial emissions.

“…are expected to have important effects on PM 2.5 variation to some extent. For example, WS can alter the dispersion state of the atmosphere, while WD provides information on the path of pollutants (Luvsan et al, 2012;Tie et al, 2015). Low PBLH, a strong temperature inversion, and descending air motion under weak surface WS can increase the frequency of haze phenomenon in China (Jones et al, 2010;Hu et al, 2012), particularly in some cities located in basin regions during winter, such as Beijing and Xi'an Lin et al, 2012).…”

Mass concentrations of PM 2.5 and PM 10 from the six urban/rural sampling sites of Xi'an were obtained during two weeks of every month corresponding to January, April, July and October during 2010, together with the six meteorological parameters and the data of two precursors. The result showed that the average annual mass concentrations of PM 2.5 and PM 10 were 140.9 ± 108.9 µg m -3 and 257.8 ± 194.7 µg m -3 , respectively. Basin terrain constrains the diffusion of PM 2.5 and PM 10 concentration spatially. High concentrations in wintertime and low concentrations in summertime are due to seasonal variations of meteorological parameters and cyclic changes of precursors (SO 2 and NO 2 ). Stepwise Multiple Linear Regression (MLR) analysis indicates that relative humidity is the main factor influencing on meteorological parameter. Entry MLR analysis suggests that SO 2 from local coal-burning power plants is still the primary pollutant. Trajectory cluster results of PM 2.5 at BRR indicate that the entrained urban pollutants carried by the westerly or winter monsoon forms the dominant regional pollution sources in winter and spring. Ultraviolet (UV) aerosol index verified the source and pathway of dust storm in spring.

“…However, improving the air quality and enhancing the environment ecological protection awareness of governments, enterprises and individuals through compensations, rather than making economic compensation, are the ultimate goals (Luvsan et al,2012). Therefore, governments must improve corresponding security mechanisms to achieve the overall goals of sustainable development of local environment and ecology.…”
