The rapid industrial development that began in the 1950's created environmental problems which consequently led to health hazards among residents of heavily polluted areas in Japan, such as Minamata Disease and Yokkaichi Asthma. Faced with these situations, the Japanese national government and local environmental authorities exerted much efforts to control pollution as well as to provide soluti...

Black carbon (BC) exerts profound impacts on air quality and climate because of its high absorption cross-section over a broad range of electromagnetic spectra, but the current results on absorption enhancement of BC particles during atmospheric aging remain conflicting. Here, we quantified the aging and variation in the optical properties of BC particles under ambient conditions in Beijing, Ch...

Background Air pollution is of particular concern in India, which contains 11 of the 20 most polluted cities in the world. Media coverage of air pollution issues plays an important role in influencing public opinion and increasing citizen demand for action on clean air policy. Hence, this study was designed to assess news coverage of air pollution in India and its implications for policy advanc...

Pollen grains can play an important role in allergic diseases and many studies have revealed that allergenicity increases in industrial cities. In Bushehr province in Iran Avicennia marina (Forsk.) Vierh. has grown in two regions, Bordekhoon (Mond protected Area) and Assaluyeh (Marine National Park of Nayband). Assaluyeh (polluted area) is an industrial region with petrochemical factories that ...

Introduction: Due to more than 1.7 million population, many vehicles and large industries around Isfahan, it has become one of the most polluted cities in Iran. The aim of this study was a spatial analysis of the concentrations of air pollutants and the air quality index (AQI). Materials and Methods: In this descriptive and evaluative study, the air quality data of 7 monitoring stations in 201...

To provide some useful information about the control of air pollution in China, we studied the spatial-temporal characteristics of air pollution in China from 2001-2014. First, we drew several line charts and histograms of the Air Pollution Index (API) and Air Quality Index (AQI) of 31 capital cities and municipalities to research the distribution across different times and cities; then, we res...

BACKGROUND AND OBJECTIVES Although the deleterious effects of air pollution from fossil fuel combustion have been demonstrated in many Western nations, fewer studies have been conducted in Asia. The Public Health and Air Pollution in Asia (PAPA) project assessed the effects of short-term exposure to air pollution on daily mortality in Bangkok, Thailand, and in three cities in China: Hong Kong, ...

Korea's urban environmental problems, specifically air and water pollution, government environmental policies, and the role of nongovernmental organizations (NGOs) in protecting the environment are described and discussed. Korea's rapid industrialization and urbanization between 1961 and 1985 led to an increased volume of waste and air pollution. Automobiles increased in number from 29,234 in...

This study aimed to quantify air pollution impact on morbidity and mortality in the Brazilian urban population using locally generated impact factors. Concentration-response coefficients were used to estimate the number of hospitalizations and deaths attributable to air pollution in seven Brazilian cities. Poisson regression coefficients (beta) were obtained from time-series studies conducted i...

Numerous studies have observed health effects of particulate air pollution. Compared to early studies that focused on severe air pollution episodes, recent studies are more relevant to understanding health effects of pollution at levels common to contemporary cities in the developed world. We review recent epidemiologic studies that evaluated health effects of particulate air pollution and conc...
