BACKGROUND Rodent models for urban air pollution show consistent induction of inflammatory responses in major brain regions. However, the initial impact of air pollution particulate material on olfactory gateways has not been reported. OBJECTIVE We evaluated the olfactory neuroepithelium (OE) and brain regional responses to a nanosized subfraction of urban traffic ultrafine particulate matter...

INTRODUCTION To address the paucity of research around smokefree streets, we: (i) refined existing data collection methods; (ii) expanded on the meagre previous research in this area; and (iii) compared results by differing size of urban centre. METHODS We refined established methods; a solo observer simultaneously observed smoking and measured fine particulate levels (PM(2.5)) on a route of ...

The paper deals with one of the methods for assessing anthropogenic impact operation ship power plants in port areas on environment. measurement mass concentration particulate matters (PM) open air was carried out during summer and winter eight points city that were selected depending conditions orographic characteristics area. Moreover, vessel traffic coastal waters assessed information number...

As a communication link between suburban and urban roads, terminals prevent buses from entering the cities, thus, they play an important role in improving traffic flow, reducing urban environmental pollution. Clearly, proximity of te rminals to cities will bring about environmental pollution in different forms (soil, water, air and wastewater). The current study tries to investigate the environ...

Exposure to elevated particulate matter (PM) pollution is of great concern both the general public and air quality management agencies. At urban traffic intersections, for example, pedestrians are often at a higher risk exposure near-source PM from while waiting on roadside or walking in crosswalk. This study offers an in-depth investigation pedestrian intersection. Fixed-site measurements near...

BACKGROUND There is a growing body of literature linking GIS-based measures of traffic density to asthma and other respiratory outcomes. However, no consensus exists on which traffic indicators best capture variability in different pollutants or within different settings. As part of a study on childhood asthma etiology, we examined variability in outdoor concentrations of multiple traffic-relat...

environmental pollution of soil, plants and deposits around highways endanger urban environment through heavy metals as the by-products of vehicles and urban industries along with other pollutants. in this research, three main highways of tehran city; namely shahid chamran, shahid hemmat and yadegar emam which had the highest rate of vehicle transportation were selected and required sampling wa...
