“…Iron oxide nitrate hydroxide was detected also in the industrial atmosphere at Site 3. The formation of nitrate salts may be linked to the high concentrations of nitrogenous gases like NO 2 and NH 3, and their corresponding salts like nitrate and ammonium in surface soil in this area which are emitted by the nitrogenous fertilizer plants adjacent to the rail track at this site (Shakour et al, 2013).…”

“…It was remarkable that the annual average concentrations shown in Figure 3 vary from one site to another in the Delta region according to the kind of activities in each site. For example, at Site 3, a high concentration of NO 2 was recorded due to the presence of nitrogenous fertilizer-producing plants close to the rail track (Shakour et al, 2013).

Purpose – The purpose of this paper is to explore the environment around the rail track at different sites in Nile Delta region, Egypt, through the measurements of the air pollutants and corrosive ionic species present in surface soil and also to investigate the impact of the existing contaminants on the composition of iron rust formed on the rail head surface at these sites and then the durability of rail itself. Design/methodology/approach – The soil characterization was studied by means of sieve shakers, pH meter, conductivity meter and ion chromatography instrument. Scanning electron microscopy, energy dispersive spectrometry, Fourier transform infrared spectroscopy and X-ray diffraction were used to characterize the rust layer formed on the rail head surface. Findings – The results showed the relation between the contaminants and the composition of the rust layer. Magnetite and goethite were the major phases identified in the rust layers. Akaganeite was detected in the marine atmosphere. Iron sulfide and iron oxide nitrate hydroxide were detected in environments rich in H2S and NO2 gases, respectively. The appearance of phases like FeCl2 and FeOCl only at marine atmospheres reflects that the corrosive species in suspended particulate matter like chloride ion have a higher effect on the rust composition of the rail head surface than that in surface soil layer. Originality/value – This paper revealed the impact of air and soil contaminants on the composition of rust layer on the rail head surface and may provide guidance for the durability of rails and the necessity for their preservation.

“…In Egypt, like all developing countries, urban air quality has deteriorated gradually because of rapid urbanization, industrialization and population overgrowth (Shakour et al, 2013). Dakahlia governorate is ranked as the fourth Egyptian governorate in number of licensed vehicles and their number is rising each year (Shoaeb and Gabr, 2016).…”

Introduction: Street vendors work daily selling their goods on the sidewalks along the streets and seldom have breaks .They are considered the most working groups that are at the highest risk of exposure to air pollution as they usually work for long hours and are continuously exposed to inevitable: adverse weather conditions, atmospheric and road dust, vehicular emissions and air pollutants from industrial and other sources, resulting in a wide range of adverse respiratory health effects. Aim of work: To assess the prevalence of respiratory symptoms and the effect of outdoor work environment on pulmonary functions measurements among female street food vendors in Mansoura city. Materials and methods: A descriptive cross-sectional study was carried upon (152) stationary female street food vendors in Mansoura city during the period from August to December 2017. The sample size was calculated using MedCalc program version18. Data was collected using a questionnaire included sociodemographic characteristics, occupational and medical histories focusing on the respiratory symptoms in the last 12 months. Clinical examination and measurement of the pulmonary functions were done. Results: There was a high prevalence of respiratory symptoms among street food vendors in the last 12 months (86.2%). The mean observed values of FEV 1 and FVC were statistically significantly lower than their predictive values and the mean observed values of FEV 1 /FVC % were statistically significantly higher than their predictive values. Conclusion: Street vendors are at high risk of respiratory symptoms and impaired pulmonary functions. Bronchial asthma ranked the first disorder for the respiratory system (18.4%) among street food vendors followed by chronic bronchitis (7.9%).
