Indoor air pollution by chlorpyrifos and S-421 applied to building timbers for the control of termite was studied. Chlorpyrifos and S-421 in indoor air were adsorbed on silica gel by suction using a diaphragm air pump, eluted with 50 ml of acetone and determined by gas chromatograph-mass spectrometry. Chlorpyrifos and S-421 levels in indoor air ranged from 0 to 0.258 and from 0.012 to 0.174μg/m3, respectively and tended to be higher in summer with a rise in atmospheric temperature than those in other seasons. Chlorpyrifos and S-421 levels in the air of the Japanese-style room are higher than those of the wash room. The chlorpyrifos and S-421 levels were found to decrease by the use of a ventilator. |
