Exposure to nitrogen dioxide (NO2) has long been linked to elevated mortality and morbidity from epidemiological evidences. However, questions remain unclear whether NO2 acts directly on human health or being an indicator of other ambient pollutants. In this study, random-effect meta-analyses wer...

Several systematic reviews have been conducted so far to examine the effect of air pollution on respiratory diseases, but there has not been a corresponding meta-analysis to estimate the effect sizes for wheeze-associated diseases/disorders, which is one of the leading causes of emergency departm...

The association between exposure to ambient air pollution and respiratory or cardiovascular endpoints is well established. An increasing number of studies have shown that this exposure is also associated with adverse pregnancy outcomes. However, the majority of research has been undertaken in hig...

Abstract: Background: Numerous epidemiological studies indicated high levels of particulate matter less than 2.5 µm diameter (PM2.5) as a major cardiovascular risk factor. Most of the studies have been conducted in high-income countries (HICs), where average levels of PM2.5 are far less compared ...

Aims: Several meta-analyses of observational studies report a long-term correlation between air pollution and the risk of cancer, particularly lung carcinoma. The aim of this study was to review and quantify evidence for an association between air pollution and the risk of developing non-lung can...

With rapid economic development and urbanization in recent decades, China has experienced the worsening of ambient air quality. For better air quality management to protect human health, Chinese government revised national ambient air quality standards (NAAQS) for particulate matter (PM) in 2012 ...

Background: There is ample evidence that short-term ozone exposure is associated with transient decrements in lung functions and increased respiratory symptoms, but the short-term mortality effect of such exposures has not been established. Methods: We conducted a review and meta-analysis of shor...

Rationale: Exacerbations are key events in chronic obstructive pulmonary disease (COPD), affecting lung function decline and quality of life. The effect of exposure to different air pollutants on COPD exacerbations is not clear. Objectives: To carry out a systematic review, examining associatio...

Abstract: We conducted a systematic review of all studies published between 1950 and 2007 of associations between long-term exposure to ambient air pollution and the risks in adults of non-accidental mortality and the incidence and mortalify from cancer and cardiovascular and respiratory diseases...

Objective: To find the correlation between exposure to PM2.5(fine particulate matter) and hypertensive disorders in pregnancy (HDP), and provide medical evidence for decreasing the incidence of hypertensive disorders in pregnancy. Method: A combination of computer and manual retrieval was used to...
