Abstract

Continuous measurements of PAN, CH(3)-C(O)OONO(2), have been carried out every hour since May 1992. The data analysis allows to show the cyclic nature of the variations in PAN content in air. Highly notable correlations to solar radiation, also to ozone and NO(x) were found. The influence of wind directions was also studied. Continous measurements of volatile organic compound (VOC) performed during a short period show that PAN concentration in air can be correlated to VOC concentrations by multiple linear regression analysis. This illustrates the quality of PAN as an indicator of photochemical activity in air. Other complementary studies were made to evaluate the potential forming of PAN in atmosphere at determined times.
