BACKGROUND AND PURPOSE Pakistan, during the last decade, has seen an extensive escalation in population growth, urbanization, and industrialization, together with a great increase in motorization and energy use. As a result, a substantial rise has taken place in the types and number of emission sources of various air pollutants. However, due to the lack of air quality management capabilities, t...
Recently, indoor air quality has attracted the attention of policymakers and researchers as a critical issue like that of external air pollution. Indoor air quality is more important as people spend time longer indoors than outdoors. Indoor environments are closed compared to external environments providing less opportunity for the pollutants to dilute. The emissions contain many substances tha...
BACKGROUND Ambient (outdoor) air pollution has been implicated as a major cause of acute cardiovascular and pulmonary illnesses and increased risk for acute and chronic effects after chronic exposures, including mortality and morbidity. In 2008, due to persistent health concerns about its workforce and their dependents, the US Mission in China began monitoring air quality at the US Embassy in B...
BACKGROUND Horizontal drilling, hydraulic fracturing, and other drilling and well stimulation technologies are now used widely in the United States and increasingly in other countries. They enable increases in oil and gas production, but there has been inadequate attention to human health impacts. Air quality near oil and gas operations is an underexplored human health concern for five reasons:...
Background and Objective: Despite the significant improve in air quality in Tehran in 2018 and reducing the average concentration of most pollutants, compared to previous years, air quality is still far from the WHO air quality guideline level and national air quality standards. The purpose of this study was to estimate the effects of air pollution on health in Tehran by considering the spatial...
Air pollution caused due to the introduction of particulate matters, biological molecules and other harmful materials into the Earth's atmosphere. Pollution brings vital diseases, death to humans, damages other living organisms such as vegetations, animals, natural environment and built environment. Data mining concerned with finding hidden patterns inside largely available data, so that the in...
Background: Air pollution is one of the most important problems in industrial cities and has affect on the lives of all people. In order to set the control programs, air pollution monitoring and determination of air quality are necessary. The aim of this study was to compare health quality of air in Tehran and Isfahan cities. Methods: This was a descriptive–analytic study . The moment conce...
ABSTRACT: Smoke haze related to biomass burning is a recurring environmental problem in Southeast Asia which has affected air quality not only in the source regions, but also in the surrounding areas. Air quality monitoring stations and meteorological stations in the region provide valuable information on the concentrations of criteria pollutants such as sulphur dioxide, nitrogen oxide, carbon ...
