Increasing industrial activity intensifies the release of different types of harmful pollutants into the atmosphere. Air pollution with dust, smoke and chemical vapor is hazardous to humans as well as to plants. This study describes the effect of air pollution resulted from brick factories and road side pollution on some morphological and physiological characteristics of Malva parviflora growing naturally around these pollution sources. The morphological traits as stem length, branch number, root length, leaf length, leaf width and leaf area as well as some physiological characteristics as levels of chlorophyll a, chlorophyll b, carotenoids and total soluble sugars were investigated. The results showed that the morphological and physiological features of Malva parviflora were reduced in the polluted areas in comparison with regions away from these areas.
