Background : Living in polluted areas could be considered a risk factor for preterm labor and low birth weight. Few studies examined the association between air pollution and abortion. The aim of this study was to determine the relationship between ambient air pollutant and rate of spontaneous abortion. Methods: This study was a case-control research conducted on 148 cases of spontaneous ab...
Air pollution are basically the foreign material in the air—can be manmade or occur naturally, and are concentrated where people are concentrated. Pollution is injurious to health and its prevention places an economic burden on the citizen. Further emission reductions from automobiles, and transportation measures and programs will be more difficult to accomplish, but the challenge has been pres...
Air pollution is a serious problem that affects billions of people globally. Although the environmental and health costs of air pollution are well known, the present research investigates its ethical costs. We propose that air pollution can increase criminal and unethical behavior by increasing anxiety. Analyses of a 9-year panel of 9,360 U.S. cities found that air pollution predicted six major...
The most common method of evaluating beneficial impacts of environmental policies is cost-benefit analysis (CBA). In the present review, CBA methods for air pollution impacts are reviewed. Three types of air pollution effects are identified, including health, productivity, and amenity. Market valuation, stated preference methods, and revealed preference methods are identified for valuing benefi...
PURPOSE OF REVIEW Current levels of air pollution are consistently associated with asthma development and morbidity among children, suggesting that current regulatory policies may be insufficient. This review will describe recent studies that have examined specific emission sources or components of pollutants that may be associated with pediatric asthma and identify subpopulations that may be p...
With China's significant role on pollution emissions and related health damage, deep and up-to-date understanding of China's air pollution policies is of worldwide relevance. Based on scientific evidence for the evolution of air pollution and the institutional background of environmental governance in China, we examine the development of air pollution control policies from the 1980s and onwards...
In this research, the effect of air pollution due to combustion of diesel oil on the performance parameters of mono-crystalline silicon (mc-Si) and polycrystalline silicon (pc-Si) photovoltaic solar panel is investigated in laboratory scale. Experiments were conducted in a solar simulator that was equipped with a chamber to control the air pollution. The air pollution is generated through the c...
INTRODUCTION Experimental and epidemiological studies have reported associations between air pollution exposure, in particular related to vehicle exhaust, and cardiovascular disease. A potential pathophysiological pathway is pollution-induced pulmonary oxidative stress, with secondary systemic inflammation. Genetic polymorphisms in genes implicated in oxidative stress, such as GSTP1, GSTT1 and ...
Nowadays, most of the research on air pollution and its adverse effects on public health in China has focused on megacities and heavily-polluted regions. Fewer studies have focused on cities that are slightly polluted. Shenzhen used to have a favorable air environment, but its air quality has deteriorated gradually as a result of development in recent years. So far, no systematic investigations...
Daily and seasonal fluctuations in mortality have been positively and significantly associated with ambient concentrations of atmospheric pollution and meteorological variables such as temperature and barometric pressure. However, much less is known about the health risk from atmospheric pollutants in the context of frequently occurring weather patterns. The objective of this study is to assess...
