Air Pollution is one of the significant problems in Tehran. Understanding the role of different sources can result in better decision-making. Some pollutions are not emitted directly from sources and are present in the atmosphere due to chemical reactions. Therefore, using air quality modeling can be beneficial to our understanding of these phenomena. An air quality modeling system was used fir...

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) t...

Three billion people in the world earn $ 1-2/day. Majority of them live in rural areas with very primitive quality of life. For example in India, which boasts of a very active space and nuclear program, around 60% of rural population have no electricity, use 180 million tons of biomass/year for cooking via primitive wood stoves and have no clean drinking water . Similar is the story in China, B...

1. introduction: increasing urbanization and industrialization rate in developed and developing countries cities, such as tehran, has led to increased air pollution. todays, the prediction and estimation of air quality parameters in urban regions are important topics in environmental studies due to their effect on human health. measurement of air quality are widely used in air quality control p...

The National Environmental Management: Air Quality Act of 2004 states that people have the right to clean air and a healthy environment. Residents of low-income settlements are exposed to high concentrations of indoor air pollution due to the burning of solid fuels such as low-grade coal and wood for space heating and cooking. Long term exposure leads to degradation in the quality of life exper...

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 ...

Proper diet, regular exercise and relaxation techniques are proven to have a beneficial effect on leading a healthy life [Spears, 1999]. Another aspect to living a healthy life is living in a clean environment. When adverse conditions exist in the environment—in the form of air pollution, solid pollution and liquid pollution—the impact on the quality of life can be substantial [Naar 1990], [Pal...

background : health professionals face the adverse health effects of climate change and air pollution in their practices. this review underscores the effects of these environmental factors on maternal and children’s health, as the most vulnerable groups to climate change and air pollution. methods : we reviewed electronic databases for a search of the literature to find relevant studies publish...
