To investigate the behavior and origins of atmospheric aldehydes, sampling of ambient air with 2, 4-dinitrophenylhydrazine-impregnated C<SUB>18</SUB> cartridge was performed at Saitama University, Urawa in the summer season, 1983 and ambient concentrations of aldehydes were determined by HPLC-UV method. Average concentrations of HCHO, CH<SUB>3</SUB>CHO, C<SUB>3</SUB>H<SUB>7</SUB>CHO (identified tentatively), and C<SUB>6</SUB>H<SUB>5</SUB>CHO in daytime were ca. 5, 3, 5, and 0.4ppb (v/v), respectively. Regression analyses between each aldehyde's concentration and O<SUB>3-</SUB>, CO<SUB>-</SUB>, or NMHC-concentration gave the suggestive data that the origins of C<SUB>3</SUB>H<SUB>7</SUB>CHO (identified tentatively) and C<SUB>6</SUB>H<SUB>5</SUB>CHO were mainly secondary formation via. photochemical reaction, and those of HCHO and CH<SUB>3</SUB>CHO consisted of both of direct emission by combustion of fossil fuels and secondary formation.
