Background: Today, air pollution is one of the major problems in large cities including Isfahan. Methods: The objective of this study was to investigate the variations of ozone (O3), carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO2), nitrogen oxides (NOx), sulphur dioxide (SO2), and particulate matter (PM10) concentrations in different months at three stations and also to explore ...

background: expanding cities with rapid economic development has resulted in increased energy consumption leading to numerous environmental problems for their residents. the aim of this study was to investigate the correlation between air pollution and mortality rate due to cardiovascular and respiratory diseases in shiraz. methods: this is an analytical cross‑sectional study in which the corre...

We used Health Impact Assessment (HIA) to analyze the impact on a given population's health outcomes in terms of all-causes mortality and respiratory and cardiovascular hospitalizations attributable to short-term exposure to particulate matter less than 10 μm diameter (PM10) in Bejaia city, for which health effects of air pollution have never been investigated. Two scenarios of PM10 reduction w...

In this paper air quality conditions in Makkah and Leeds are compared. These two cities have totally different climatic conditions. Makkah climate is characterised as hot and dry (arid) whereas that of Leeds is characterised as cold and wet (temperate). This study uses air quality data from 2012 collected in Makkah, Saudi Arabia and Leeds, UK. The concentrations of all pollutants, except NO are...

Diagnosis of lameness caused by lesions of the distal limb requires a thorough clinical examination, including careful palpation, manipulative tests, hoof tester evaluation, examination of the horse in hand and under saddle, and regional anesthesia. Specific causative lesions may require technical imaging modalities to fully evaluate. Author’s address: Fairfield Equine Associates, PC, 32 Barnab...

OBJECTIVES The purpose of this study was to examine the association between ambient air pollution and hospitalization for respiratory infections among children who were younger than 15 years in Toronto during a 4-year period (1998-2001). METHODS Exposures averaged during periods that varied from 1 to 7 days were used to assess the effects of air pollutants, including thoracic particulate matt...

Partitioning of major and trace components in PM10–PM2.5–PM1 at an urban site in Barcelona (Spain) in the Western Mediterranean was studied in the period 2005–2006. Particular attention was paid to the partitioning of mineral matter and to the evidence of possible interactions of mineral matter with other pollutants (gaseous pollutants and secondary PM). The results showed a high contribution o...
