Introduction. This study aims to assess the factors associated with 25-hydroxy vitamin D (25(OH)D) levels in pregnant women and their newborns in a sunny region. Materials and Methods. This cross-sectional study was conducted in 2012 in Isfahan, Iran. It comprised 100 nulliparous singleton pregnant women, selected by random cluster sampling. Laboratory tests were assessed before delivery in mot...
Health impact assessment has become important in the development of air quality policies and in finding the relationships between pollutants concentration and health effects. In our work we presented a novel index able to evaluate the effects on the human exposure caused by ambient air pollution in urban areas. The index is able to link both health risk factors and pollutants levels. The indexe...
In recent years, air pollution has become a serious threat, causing adverse health effects and millions of premature deaths in China. This study examines the spatial-temporal characteristics ambient quality five provinces (Shaanxi (SN), Xinjiang (XJ), Gansu (GS), Ningxia (NX), Qinghai (QH)) northwest China (NWC) from January 2015 to December 2018. For this purpose, surface-level aerosol polluta...

Background and aimsIn recent years, because of excessive population growth, increasing of vehicles and developing of the industries, Tehran has been encountered with seriousenvironmental crisis, such as air pollution. So, for setting the control programs, air pollution monitoring and determination of Tehran air quality are necessaryMethodsIn the present study, Tehran air quality index (AQI) was...
We used physical and pharmacokinetic modeling to estimate personal exposures to respirable particle (RSP) and carcinogenic particulate polycyclic aromatic hydrocarbon (PPAH) air pollution from second-hand smoke (SHS) from the increase in urinary cotinine of eight patrons of three bars in Bismarck, North Dakota. We compared SHS-RSP levels to the U.S. Air Quality Index (AQI), used to forecast out...
The Iowa City Landfill in eastern Iowa, United States, experienced a fire lasting 18 days in 2012, in which a drainage layer of over 1 million shredded tires burned, generating smoke that impacted the surrounding metropolitan area of 130,000 people. This emergency required air monitoring, risk assessment, dispersion modeling, and public notification. This paper quantifies the impact of the fire...
Introduction: Air pollution is one of the most important problems in recent century, which threats humans' health. This study was conducted to assess air pollution with respect to PM10, SO2, CO, NO2, H2S, and Air Quality Index (AQI), in a location in close proximity to Bandar Abbas oil refinery. Methods: In this study a location in close proximity to Bandar Abbas oil refinery was selecte...
