The rapid economic development and motorization in the last three decades in Beijing has resulted in the deterioration of Beijing’s air quality. Since 1998, the Beijing municipal government has made a great effort to improve Beijing’s air quality, resulting in significant progress in reducing air pollution in Beijing. However, the air quality is still below the international health standard, es...
Mercury pollution is a persistent and increasing problem in the environment. Along with some natural sources of the metal, major man-made sources of mercury pollution include incinerators, fossil fuel plants, and municipal sewage systems. The EPA estimated that in 1989, approximately 643,000 kg of mercury was discarded as municipal solid waste, with 84% of it landfilled.
Taking Handan City (the south of Northern China) as an example, and making use of the environmentally friendly materials of Handan Environmental Monitor Station in 2013-2014, the surface observational data of Handan Meteorological Station and the sounding data of Xingtai station, combined with the integrated analysis of numerical prediction and simulation, this paper shows that, in 2014, the ai...
China faces unprecedented air pollution today. In this study, a database (SO2, NO2, CO, O3, PM2.5 (particulate matter with aerodynamic diameter less than 2.5 μm), and PM10 (particulate matter with aerodynamic diameter less than 10 μm) was developed from recordings in 188 cities across China in 2014 and 2015 to explore the spatial-temporal characteristics, relationships among atmospheric contami...
Indoor air pollution, specifically restricted in its meaning to chemicals in home indoor air environment, presents a new and probably an important challenge to the researchers of the air pollution field. The general overview of this topic suggests that the voluminous data generated in the past ten or so years have only defined the rudiments of the problem, and significant areas of research stil...
Introduction Polybrominated diphenyl ethers (PBDEs) are a class of flame retardants that were added to thousands of consumer products, such as thermoplastics, electronic equipment, and textiles (Hale et al., 2001).Research has revealed that municipal sewage could be a significant source of PBDEs contamination that is ubiquitous throughout the environment (North, 2004; Song et al., 2006). The Pe...
Tree planting has been proposed by the municipal government as a measure to alleviate air pollution in Beijing, the capital of China. This study examines that proposal. It is based on the analyses of satellite images and field surveys to establish the characteristics of current urban forest in the central part of Beijing. The influence of the urban forest on air quality was studied using the Ur...
Municipal solid waste management (MSWM) is the fundamental environmental management in urban area, the characteristic of uncontrolled burning of wastes and improper incineration contributes significantly to urban air pollution needed for citizen life. This study proposed 18 criteria on Taipei metropolitan using interpretive structural modeling (ISM) with interrelationships among the criteria, i...
Few prospective studies have assessed the blood pressure effect of extremely high air pollution encountered in Asia's megacities. The objective of this study was to evaluate the association between combustion-related air pollution with ambulatory blood pressure and autonomic function. During February to July 2012, personal black carbon was determined for 5 consecutive days using microaethalomet...
