“…Globally, air pollutant levels are disproportionately higher in urban centers compared to rural settings [100, 41, 40, 101–103, 86, 32, 104]. Acute exposure to both PM 2.5 and PM 10 led to acute rises in arterial blood pressure (BP) in urban centers in the US mostly inhabited by minority groups, namely African Americans [57, 52].…”

“…These Asian megacities have air pollution levels up 10 times the US NAAQS [38, 37]. In a nationwide time-series analysis in 272 major Chinese cities, both short-term exposure to SO 2 (per 10μg/m 3 increments) and CO (per 1 μg/m 3 increments) were associated with a 0.70% increase and a 1.12% increase in overall CVD mortality, respectively [41, 42]. In a meta-analysis of 59 studies from China where mean PM 2.5 exposures were between 39 to 177 μg/m 3 , each 10μg/m 3 increment was associated with a 0.63% increase in overall CVD mortality [37].…”

Air Pollution and Cardiovascular Disease: a Focus on Vulnerable Populations Worldwide

et al. 2018

Purpose of review: Certain subgroups defined by sociodemographics (race/ethnicity, age, sex and socioeconomic status [SES]), geographic location (rural vs. urban), comorbid conditions and country economic conditions (developed vs. developing) may disproportionately suffer the adverse cardiovascular effects of exposure to ambient air pollution. Yet, previous reviews have had a broad focus on the general population without consideration of these potentially vulnerable populations. Recent findings: Over the past decade, a wealth of epidemiologic studies have linked air pollutants including particulate matter, oxides of nitrogen, and carbon monoxide to cardiovascular disease (CVD) risk factors, subclinical CVD, clinical cardiovascular outcomes and cardiovascular mortality in certain susceptible populations. Highest risk for poor CVD outcomes from air pollution exist in racial/ethnic minorities, especially in blacks compared to whites in the U.S, those at low SES, elderly populations, women, those with certain comorbid conditions and developing countries compared to developed countries. However, findings are less consistent for urban compared to rural populations. Summary: Vulnerable subgroups including racial/ethnic minorities, women, the elderly, smokers, diabetics and those with prior heart disease had higher risk for adverse cardiovascular outcomes from exposure to air pollution. There is limited data from developing countries where concentrations of air pollutants are more extreme and cardiovascular event rates are higher than that of developed countries. Further epidemiologic studies are needed to understand and address the marked disparities in CVD risk conferred by air pollution globally, particularly among these vulnerable subgroups.

“…A positive correlation between CO and total dynamic stroke mortality and dynamic mortality in both age categories was observed, which is also consistent with previous studies. Liu et al demonstrated that short‐term exposure to ambient CO was associated with increased mortality from cardiovascular disease in China . The reason why a correlation between CO and total stroke mortality was apparent only during the cold season may be explained by the higher concentrations of CO that occur at this time of the year because of increased fuel use.…”

“…For example, a study in China demonstrated that air pollution affected stroke mortality, and other studies have noted a relationship between stroke mortality and outdoor and traffic‐related air pollution . Similarly, there have been a large number of studies that also use mortality to indicate the risk of stroke . Thus, mortality is regarded as the most appropriate indicator of stroke risk.…”

Summary This study aims to examine the correlations between air pollution and dynamic stroke mortality, which is defined as the daily real‐time number of deaths from stroke. Death data were obtained from daily medical records of 7230 incidents from the Center for Disease Control and Prevention in the Longquanyi District of China from 2016 to 2017. Air pollution data were obtained from environmental monitoring stations in the Longquanyi District. Time series analysis using generalized additive Poisson regression models was applied, and single‐pollutant and two‐pollutant adjusted models were utilized. Furthermore, categories based on gender, age, and meteorological factors were considered in the analysis. The results indicated that PM2.5, PM10, O3, and CO had significant effects on dynamic stroke mortality, which were stronger for older people and during the cold season. This study helps hospital managers, patients, and governments seeking to prevent and control the effects of air pollution on the risks of stroke.

Stability challenges and prospects for the industrial application of non‐noble catalysts for selective catalytic reduction of NO_x by CO (CO‐SCR)

The selective catalytic reduction of NOx by CO (CO‐SCR) holds considerable promise as a simple and cost‐effective technology capable of concurrently removing CO and NOx from mobile and stationary sources. This is especially pertinent for industry sectors with high CO emissions, such as the iron and steel industry, making CO‐SCR an attractive solution with significant industrial applicability. However, the widespread adoption of this technology faces several limiting factors, of which the impacts of SO2, H2O, and O2 on catalyst performance and stability are most pronounced. Current research into these specific constraints is not yet exhaustive, rendering the comprehensive industrial implementation of CO‐SCR technology a challenging endeavour. As such, this review paper seeks to concentrate on variables that impede the industrial utilization of CO‐SCR technology. It encapsulates the existing bottlenecks and underscores the criticality of resolving the inhibitory effects of O2 on the CO‐SCR reaction as the most pressing issue in contemporary research.
