Introduction: Inequalities in urban environment are a significant concern. Socioeconomic level plays an important
role in these inequalities. Inequality in environmental hazards is recognized as potential determinants of health
disparities.
Materials & Methods: In this study, we used individual and cumulative environmental hazard inequality indices to
compare the inequality among 379 neighborhoods in the city. Inequality indices were calculated based on unequal
shares of environmental hazards for socioeconomic status (SES). The hazards include ambient concentrations of
PM10 and NO2 in 2011.
Results: Results revealed that inequalities from cumulative hazards (additive and multiplicative) and individual PM10
in different education rates were significant (P<0.001). However, there was no significant relation between
inequalities in distribution of the pollutants and the variable of unemployment rate (P>0.05).
Conclusion: Findings of this research can be useful for policymakers and managers to investigate environmental
justice especially in mega cities
