“…Several studies have analyzed air mass quality and meteorological datasets in order to interpret atmospheric aerosol levels in European and Asian cities (Hien et al, 2002;Yang, 2002;Oanh et al, 2006). Smith et al (2001) used 3-year PM 10 data sets from three monitoring sites, in combination with relevant air trajectory and meteorological data, to identify factors influencing particulate matter levels in Greater London.…”

This study investigates the effects of sea-land breezes (SLBs) and northeastern monsoon (NEM) on the physicochemical properties of particulate matter (PM) in the atmosphere over southeastern coastal region of Taiwan Strait. The intensive PM sampling protocol was consecutively conducted for forty-eight hours. During the sampling periods, PM 2.5 and PM 2.5-10 were simultaneously measured with dichotomous samplers at four sites (two inland and two at offshore sites) and PM 10 was measured with beta-ray monitors at these same four sites. Strong SLBs were regularly observed in the coastal region of southern Taiwan during the SLBs periods, while significant northeastern monsoons appeared during the NEM periods. The mass ratios of PM 2.5 /PM 10 during the NEM periods were always higher than the SLBs periods. The most abundant ionic species of PM were SO 4 2-, NO 3 -, and NH 4 + . The most common chemical compounds of PM in southern Taiwan were ammonium sulfate ((NH 4 ) 2 SO 4 ) and ammonium nitrate (NH 4 NO 3 ). Carbon contents of PM during the NEM periods were higher than during the SLBs periods. The organic-to-elemental-carbon ratio (OC/EC) of PM 2.5 ranged from 1.05 to 4.39 with an average of 2.26. The order of major metallic elements of PM 2.5 in the SLBs and NEM periods is Fe > Ca > K > Al > Mg > Zn > Pb and Ca > Fe > Al > K > Mg > V > Ni, respectively, and of PM 2.5-10 is Ca > K > Al > Fe > Mg > Zn and Fe > Ca > Al > K > Mg > V > Ni, respectively. This study reveals that the accumulation of PM offshore, due to land breezes, influences the tempospatial distribution of PM at the coastal region in southern Taiwan. Moreover, the nss- [

“…Wind speed and air temperature are important determinants of PM 2.5 (Tai et al, 2010;Jung et al, 2002;Hien et al, 2002). As expected, these parameters were inversely related to particulate matter concentrations.…”

“…As expected, these parameters were inversely related to particulate matter concentrations. Stable meteorological conditions will occurred when low wind speeds combined with temperature inversions, which limited the dispersion of pollutants, cleared fine particulates, and induced high PM concentration (Hien et al, 2002). A high temperature in the tropics usually increases the amount of soil dust from the Earth's surface that coming from the biomass burning and the evaporation of materials (Azmi et al, 2010).…”

“…Levels of semi-volatile nitrate and organic aerosol species are temperature and relative humidity dependent [17]. A further study [18] revealed that fine particles are controlled mainly by wind and temperature and 60% to 74% day-today variation of particulate matter concentrations can be reasoned by meteorological parameters and that any change of the concentration of PM 2.5 is well related to pressure, relative humidity, and wind speed.…”
