Due to their detrimental effects on human health, the scientific interest in ultrafine particles (UFP) has been increasing, but available information is far from comprehensive. Compared to the remaining population, the elderly are potentially highly susceptible to the effects of outdoor air pollution. Thus, this study aimed to (1) determine the levels of outdoor pollutants in an urban area with...

objectives: to investigate the differences in death after receiving emergency services in traffic accidents between urban and rural regions, and decompose factors of the gap in langerood, northern iran. methods: this cross-sectional study was conducted in langrood, northern iran during a 1-year period from 2013 to 2014. the hospital data of traffic crashes were used. data contained those patien...

Little is known regarding levels and source strength of carbonaceous aerosols in Scandinavia. In the present study, ambient aerosol (PM10 and PM2.5) concentrations of elemental carbon (EC), organic carbon (OC), waterinsoluble organic carbon (WINSOC), and water-soluble organic carbon (WSOC) are reported for a curbside site, an urban background site, and a suburban site in Norway in order to inve...

The general population is exposed to particulate air pollution from many different local and regional sources. Examples of local sources are traffic, biomass burning and resuspended dust, while regional sources are dominated by combustion processes from heating, traffic and industries. The overall aim of this thesis was to characterise the personal exposure to trace elements in fine particles, ...

Vehicle traffic pollution requires complex physicochemical analysis besides emission level measuring. The current study is focused on two campaigns of emissions measurements held in May and September 2019 Alba Iulia City, Romania. There was found a significant excess PM2.5 for all measuring points PM10 the most circulated during May, along with VOC CO2 emissions. reveal threshold PM increased v...

Organic matter extracts were obtained from particulates recovered from 10,000-m3 air samples collected in Sicily (Italy). The overall concentrations of acenaphthene, benzo(a)pyrene, phenanthrene, anthracene, fluoranthene, and pyrene were 526 ng/m3 air in a highly polluted urban area and 48 ng/m3 in a rural area affected by motor vehicle traffic pollution. After metabolic activation, both sample...

With the rapid development of urban traffics, recently many big cities have established lots of modern traffic networks extended in all directions, but there are still some severe problems caused by traffic congestions and traffic accidents. So for improving these unsatisfactory states in the urban traffic, inspired by the immune cooperative phenomenon from the biologics, firstly the regional t...
