RELATIONSHIP BETWEEN THE CONCENTRATIONS OF PM2.5 INDOORS OBTAINED BY USING THE OPTICAL AND GRAVIMETRIC METHODS: PRELIMINARY ANALYSIS

(Cgrav/Copt) is linear or not. If this ratio can be described by the linear function, calibration of the optical method should be very simple. If not, calculation of “real” PM2.5 mass concentrations using data obtained from optical devices becomes more complicated. Especially, if this relationship could be described by the exponential function, the ratio would be very sensitive to even small changes in different environmental factors. In this context, it is important to note that light scattering
