Meteorological conditions play a crucial role in ambient air pollution by affecting both directly and indirectly the emissions, transport, formation, and deposition of air pollutants. In this study, the relationships between meteorological parameters and ambient air pollutants concentrations in three megacities in China, Beijing, Shanghai, and Guangzhou were investigated. A systematic analysis ...

BACKGROUND Recent studies have demonstrated the utility of social media data sources for a wide range of public health goals, including disease surveillance, mental health trends, and health perceptions and sentiment. Most such research has focused on English-language social media for the task of disease surveillance. OBJECTIVE We investigated the value of Chinese social media for monitoring ...

The increasing population, urbanization and industrial growth are causing serious environmental challenges including air pollution worldwide. According to WHO, the indoor and outdoor air pollution exposure has caused around 7 million deaths globally only in 2012. The major air pollution sources include transportation and petrochemical based industry. Motor vehicle repair workshops (MVRW) pose m...

D espite recent advances in the treatment of heart failure with reduced ejection fraction (HFrEF), adverse event rates remain high with >50% mortality at 5 years (1). The progressive nature of HFrEF coupled with high mortality and rehospitalization rates (2) mandates greater attention to previously underappreciated etiologies of heart failure (HF) exacerbation, including environmental exposures...

China has recently made available hourly air pollution data from over 1500 sites, including airborne particulate matter (PM), SO2, NO2, and O3. We apply Kriging interpolation to four months of data to derive pollution maps for eastern China. Consistent with prior findings, the greatest pollution occurs in the east, but significant levels are widespread across northern and central China and are ...

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 ...

OBJECTIVES Epidemiological studies have demonstrated associations between long-term exposure to traffic-related air pollution and coronary heart disease (CHD). Atherosclerosis is the principal pathological process responsible for CHD events, but effects of traffic-related air pollution on progression of atherosclerosis are not clear. This study aimed to investigate associations between long-ter...

This commentary addresses some of the diverse questions of current interest with regard to the health effects of air pollution, including exposure-response relationships, toxicity of inhaled particles and risks to health, multipollutant mixtures, traffic-related pollution, accountability research, and issues with susceptibility and vulnerability. It considers the challenges posed to researchers...

BACKGROUND To propose a new method for including the cumulative mid-term effects of air pollution in the traditional Poisson regression model and compare the temperature-related mortality risk estimates, before and after including air pollution data. RESULTS The analysis comprised a total of 56,920 residents aged 65 years or older who died from circulatory and respiratory diseases in Belgrade...

As the largest developing country in the world, China has achieved rapid economic development, averaging an annual gross domestic product (GDP) growth rate of 10% over the past two decades. But this success comes at the cost of deterioration of the environment. China's environmental problems, including outdoor and indoor air pollution, water shortages and pollution, desertification, and soil po...
