Traffic–related pollutant has been recognized as an air pollution hot spot due to its large emission rate and great health impacts for the exposed population. In the present investigation, a computational fluid dynamics technique is used to evaluate the effect of traffic pollutions on indoor air quality of a naturally ventilated building. The transport of street-level nonreactive pollutants emi...

BACKGROUND In the past few decades, Indoor Air Pollution (IAP) has become a primary concern to the point. It is increasingly believed to be of equal or greater importance to human health compared to ambient air. However, due to the lack of comprehensive indices for the integrated assessment of indoor air quality (IAQ), we aimed to develop a novel, Fuzzy-Based Indoor Air Quality Index (FIAQI) to...

The sol-gel process is a wet-chemical technique (chemical solution deposition), which has been widely used in the fields of materials science, ceramic engineering, and especially in the preparation of photocatalysts. Volatile organic compounds (VOCs) are prevalent components of indoor air pollution. Among the approaches to remove VOCs from indoor air, photocatalytic oxidation (PCO) is regarded ...

As the transportation sector is one of main emitters large quantities pollutions to atmosphere, industries have been trying cope with this issue and launch many campaigns or projects reduce air pollutions. In any around world, an electric vehicle a part alternative mode which has recently experienced considerable growth. The paper aims evaluate energy consumption greenhouse gas (GHG) emissions ...

It is an extremely urgent problem that physical fitness promotion must face not only the increasing air pollution but also the decline of physical activity level of children and adolescents worldwide at present, which is the major reason that forms an inactive lifestyle and does harm to adolescents' health. Thus, it is necessary to focus on the exposure factor in environmental health risk asses...

Aquatic organisms are used extensively in water quality assessment and ecosystem health quantity scale in streams. Mohammad-Abad creek (Golestan Province) is accounting one of the tributary streams of Gorgan-Rood River. In this study, 21 sites were selected along 25 kilometers of stream long according to ingredient pollutants. Sampling took place each 45 days. After segregation and identificati...
