Background & Aims of the Study: Dust as a phenomenon is among the significant problems
in numerous regions of Iran and other countries. Empirical equations can be used to estimate the
concentration of particulate matter. This study evaluated computational values of suspended particles
less than ۱۰ μm with their actual concentration in Ahvaz city based on a linear regression model.
Materials and Methods: This descriptive cross-sectional study was conducted from April ۲۰۱۶
to March ۲۰۱۸. The dust images were obtained from the MODIS sensor of the Aqua satellite. The
meteorological data included ۳-hour horizontal visibility data recorded in m. PM۱۰ concentration
data were obtained from the Environment Organization. Accordingly, ۵ empirical equations
between horizontal visibility and PM۱۰ have been used in this case. The calculated values of
particulate matter less than ۱۰ μm in Ahvaz City, Iran, were evaluated with actual values of PM۱۰
based on the linear regression model.
Results: The study results suggested that the computational R index for empirical equations had
higher accuracy in ۲۰۱۷ data. The coefficients of determination using D’Almeida (۱۹۸۶), Dayan
(۱۹۸۶), Chung (۲۰۰۳), Jugder et al. (۲۰۱۴), and Camino et al. (۲۰۱۵) indicators were calculated
as ۰.۸۷, ۰.۸۰۶, ۰.۷۴۵, ۰.۸۷۳, and ۰.۸۶۶, respectively.
Conclusion: Jugder et al. (۲۰۱۴) index with R² equal to ۰.۵۴۸۶۶۷ was the best index for
estimating PM۱۰ in this region. The study results showed that empirical equations could estimate
particulate matter and dust in southwestern Iran
