A simple passive type sampling device has been developed for personal monitoring of ozone exposure in the workshop of welding. Atmospheric ozone is collected on a filter paper soaked in l,2-di-(4-pyridyl)-ethylene. Pyridine-4-aldehyde is produced by the ozonolysis reaction. Analysis of the results showed the time-weighted (TWA) exposure concentration of ozone. The relationship showed a good linearity between the pyridine-4-aldehyde produced and the ozone concentration. Coefficient of variation of the data of measurement after exposure was less than 10%, and the range of the data was from 0.05 to above 1.42 ppm hr. Promising results have been obtained in the data of controlled exposures to nitrogen dioxide, and excellent stability for delayed analysis after sampling. According to these results, we believe that the simple sampling device can be used for the evaluation of personal exposure dose for ozone.
