PM10, NOx, and O₃ were measured at six locations, of which each three is horizontally and vertically distributed respectively, in an apartment complex around the heavily traffic road. Those were measured seven times a day with two hours interval starting from 8 o’clock in the morning for 15 days during May 2005~September 2005. PM10 and NOx showed high concentrations in rush hours while low concentrations in midday due to the direct emissions from automobiles in operation. Temporal variations of O₃ showed very much similar trend appeared in normal urban atmospheres.
The spatial distributions of PM10, NOx and O₃ showed that almost all of concentrations were higher in a row of Roadside>Surface at 130 m apart from the road>Surface at 230 m apart from the road>3rd floor of apartment building>15th floor of apartment building>27th floor of apartment building.
Model equations, which can project spatial concentration distributions, were constructed by combining the horizontal and the vertical linear regression equations derived from six mean values corresponding to six measuring locations.
According to inter-comparison of PM10, NOx, and O₃ with the constructed model equations, concentration gradients were higher in a row of Vertical direction of NOx>Vertical direction of PM10>Horizontal direction of NOx>Horizontal direction of PM10>Vertical direction of O₃>Horizontal direction of O₃. Why concentration gradient of particulate PM10 is lower than that of gaseous NOx is in question, and should be studied.
