Background: The undesirable condition of air quality is one of the most important environmental problems that have challenged many of the world's cities. In this study, considering the importance of particle matter as one of the most important atmospheric pollutants in Ahwaz, the main objective is the air quality assessment of this city in terms of PM2.5 and PM10 in 2016-2017. Methods: The air ...
air in the intracranial vascular compartment is rare and only few case reports are published in the literature. without surgery or open head trauma, the origin of air bubbles in the venous sinus is still debated. we report an admitted patient in the emergency room one hour after a severe closed head injury, and in whom, the post-surgical cranial ct scan demonstrated feature of air embolism alon...
microbial oil has high similarity to the oil obtained from plants and animals. they are renewable sources that can be used for different purposes such as production of biofuels. biofuels are renewable, biodegradable, and nontoxic, which makes them highly environmentally friendly. producing oil from yeasts has more advantages than that from plants. accordingly, isolation of oleaginous yeasts wit...
aims: air is the combination of atmospheric components or physical conditions of the current atmosphere in a certain place and a certain time. the aim of this study was to assess the relationship between weather components, air atmospheric pollutants and the number of individuals that were hospitalized due to cardiovascular diseases in polluted days. instrument & methods: in this descriptive st...

There is currently scarce information on the occurrence and distributions of Polycyclic Aromatic Hydrocarbons (PAHs) in the air from industrial estates in Nigeria. Hence, the present study aims to evaluate the extent and sources of pollution of polycyclic aromatic hydrocarbons in the air from some industrial estates in Lagos and Ogun States, Nigeria. Ten air samples have been collected from the...
Background and Aim: One of the notorious air pllutants on which air quality is determined is carbon monoxide (CO). The aim of the present study was to measure the concentration of CO outdoor and indoor urban environments and compare it with air quality standards within buildings and open spaces. Materials and Methods: This research was a descriptive-analytical study of CO estimation in ou...
