Background: Kuwait State is branded by the recurrent dust storms and high pollution level. It has the highest dust concentration and surface temperature in Peninsula. The aim of the present study was to assess the respirable particulates during days with and without dust storms in two residential areas in Kuwait State. Materials and Methods:This time-series comparative study was accomplished during the period from 1 January 2013 to 31 December 2013. It was conducted by recording the local meteorological data in the two sampling stations at Mansoria (A) and Ali Sabah Al-Salem (B) residential areas, in addition to the sampling and analysis of respirable particulates (PM10) using the SOP-10 High-Volume PM10 Samplers' Standard Method. Results: There were 256 and 278 measurement days (70.1 and 75.1% of the yearly days) in monitoring stations A and B, respectively, with a total of 119 (46.5%) and 134 (48.2%) days with dust storms, respectively. The daily concentrations of PM10 were higher than the National Ambient Air Quality Standards of Kuwait State (150 µg/m3) at the two stations. The annual PM10 concentration of B station [192.5 (264.5) µg/m3] was nonsignificantly higher than that of A [191.2 (182.7) µg/m3]. At the two stations, the levels of PM10 during days with dust storms were significantly higher than that during days without. Conclusion: Respirable particulate is slightly higher in Ali Sabah Al-Salem than in Mansoria. Days with dust storms have significantly greater PM10 levels than those without. The study recommends application of land-use planning, and windbreaks, combating desertification, and enhancing stoppage of outdoor activities during dust storms among public.

This variationist study attempts to provide an insightful profile of the slum vernacular of the Cairene dialect via formal and social analyses of some vocabulary, phrases, and expressions. It investigates how language varies among the slum speakers in Cairo and what are the social and linguistic roles that this variation plays. The corpus of this study has been attained through close observations, repertoire, and immediate communication with the slum speakers in Cairo. The formal analysis of this study concluded that this variation is often based on the linguistic deviation that poets, dramatists, and novelists use to be creative, inventive, or different. The correlation between the variation and the socioeconomic status of the slum speakers in Cairo is intriguing and suggests that the social setting plays a crucial role in shaping the speech in a given community. The study has revealed that variation in the Cairene dialect functions as an index of the social factors such as socioeconomic status and the area of residence that are distinctive to the Cairene slum communities and helps establish rapport among the slum speakers in Cairo. Moreover, many words and expressions of the Cairene slum vernacular in Cairo have diffused in the prestigious variety for social and linguistic reasons. The study has pointed out that the impact of the Cairene slum vernacular on the youth of the prestigious variety is patent. The two varieties are separably used in their talk and this gives the Cairene dialect a diglossic nature as they confine each variety for some specific uses.
