The safety performance of the industrial enterprises in Khartoum city was the best. The safety performance in the chemical sector was the worst with regard to FSI and DAFR. The age, sex, and educational level of injured workers greatly affect safety performance.
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.
Background: Air pollution index is not applied in Egypt up till now. Objectives: This study is a trial to apply the concept of air pollution index (API) to assess the air quality and its health concerns at one of the heavy traffic streets in Alexandria; Egypt. Methods: This was a case study that was conducted over one year, the setting of which was one of the heavy traffic streets. The total suspended particulate matter (TSP) was sampled using "High Volume Air Sampler," for 24 hours/day with simultaneous measurement of local meteorological parameters. Results: The total suspended particulates exceeded the National Standards during 78 measurement days out of 84 (92.9%). Application of air pollution index revealed that 19% of the measurement days were of good air quality, 28.6% harmful for sensitive groups, 20.2% unhealthful for the public, 15.5% very unhealthy, and 16.7% hazardous to the public. Conclusion: Traffic concentrations of TSP at the streets under study exceeded the Egyptian National Standards during all weekdays and all months throughout the year. The air quality during the working days (Sunday to Thursday) was unhealthy to the general population. The API was the highest during Spring Season. Application of an air pollution control strategy with generalization and communication of air pollution index in Egypt were recommended.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
