Dust particles are suspended particles created from various natural and anthropogenic sources. Dust particles contain toxic metals, such as mercury (Hg), which can have harmful effects on the human health. In this study, to investigate the contamination level of Hg in the street dust in Ahvaz, 95 dust samples were collected from the pavements in the main streets. The concentration of Hg in the collected samples was determined by the atomic absorption method (ASS). The contamination level was estimated based on indicators such as contamination factor (Cf), enrichment factor (EF), geo-accumulation index (Igeo) and ecological risk index (Er). The concentration value of mercury ranged from 0.02 to 8.75 mg/kg with an average of 2.53 mg/kg. The results of pollution indicators showed that the level of Hg contamination in the street dust of Ahvaz was a high level of contamination. In addition, the results of ecological risk assessment indicated that the ecological risk of Hg in the study area was very high. Spatial distribution pattern of Hg concentration showed that in areas with high population density, high traffic volume and industrial activities, there was a high pollution level of Hg.

Imam Mahdi's revolution also follows the same rule and requires signs before its emergence. There signs were mentioned in widely-cited traditions and Hadiths. In the present article, using descriptive and evidence of poems, the author discussed signs of emergence in contemporary Arabic poetry and Persian.

Contemporary poets have opened a new door to poem and literature, named Mahdavi literature, and they have introduced imam Mahdi as the savior of last times to the seekers of truth from the window of poem. Referring to some evidence of the poems of these poets, the present descriptive-analytic paper is going to examine the idea of expectation and the identity based on culture and civilization with reference to the commentaries of the Quran and widely transmitted narrations .The Persian and Arabic contemporary Shiite poets have described Imam Mahdi's features and the expectation for the Promised in their Mahdavi poems.

Sayyed Reza Mosavi Hendi, Shekh Mohsen Abolhob, Salman Harati, Gheisar Amin pour are among the renowned contemporary poets devoted to this belief. The present article, through a descriptive-analytical method and reliance on instances in the poetry of these poets, has comparatively investigated the portrait of Imam Mahdi in contemporary Persian and Arabic poetries. Discussions such as the birth of Imam Mahdi (aj), absence, anticipation, glad tidings on the appearance of the Savior in the Apocalypse, describing the characteristics of the Mahdavi utopia are among the common themes in the poetry of poets under discussion. But issues such as titles, Return and responses to deviations on subjects related to Mahdaviat could be seen in the poetry of some of them such as Sayyed Reza Mousavi Hendi’s.
