Abstract: | In this study, the relation between sulfur dioxide (SO2) and particulate matter (PM) concentrations periodically measured in the city of Afyon’s atmosphere with meteorological factors
such as precipitation, humidity, temperature, wind velocity, and inversion were investigated. The mean values of SO2 and PM concentrations measured during the winter months of October–March 1990–1999 were correlated with the meteorological
parameters of the same period. Simple and multiple linear regression analysis were utilized to evaluate the contribution of
meteorological variables. The statistical results show that the pollutants, i.e., SO2 and PM are dependent upon humidity, temperature, and inversion at the 1% significance level; while the dependence of both
pollutants with temperature is negative when those of humidity and inversion are positive. Two models in which temperature
and inversion are dependent with multiple variables are recommended for predicting the contribution of meteorological parameters
on SO2 and PM. In addition, the relationship between humidity, temperature, and inversion with pollutants is also determined using
nonlinear (polynomial) models. |
