Cardiovascular effects of traffic-related air pollution: A multi-omics analysis from a randomized, crossover trial.

We conducted a randomized, crossover trial in 56 young adults, who participated in two 4-hour exposure sessions on a main road and in a park alternately, to help determine the causes of TRAP's cardiovascular effects. TRAPs with exception to fine particulate matter in the road session were 2-3 times higher. Changes in blood pressure or HRV were also associated with changes in these TRAP-related molecular biomarkers. Our study provided systematic mechanistic profiling for the cardiovascular effects of TRAP using multi omics, which may have ramifications with TRAP monitoring.

What Is "Socioeconomic Position (SEP)," and How Might It Modify Air Pollution-Health Associations? Cohering Findings, Identifying Challenges, and Disentangling Effects of SEP and Race in US City Settings.

Given that, lower-income and minority groups in the United States are oftendisproportionately exposed to pollution, epidemiology has long thought that socioeconomic status has long been a determinant of polluting impacts on health. A growing body of literature has shown that lower-SEP populations may also be more vulnerable to pollution in recent decades. To distinguish causal components and move closer to identifying causal factors, environmental epidemiology is becoming more familiar with issues of differential susceptibility.

Resolving and Predicting Neighborhood Vulnerability to Urban Heat and Air Pollution: Insights From a Pilot Project of Community Science.

For the first time, community members' records reveal the importance of both the large spatiotemporal shifts and covariations between 2 m air temperature and ozone concentration within the neighborhood scale. This neighborhood variation was not present in either daily satellite observations or operational model forecasts, which makes the assessment of community health risks a challenge. In comparison, a satellite-based land surface temperature at 1 km resolution is insufficient to record air temperature variations at the neighborhood scale. The potential of green canopy to reduce air temperature and ozone can be enhanced by interactive maps and apps that display the predictions in near real time, as well as the potential of green canopy to reduce air temperature and ozone; however, different tree species and sizes may have different impacts on air temperature, which are not addressed by the WRF-Chem.

Effect of traffic-related air pollution on cough in adults with polymorphisms in several cough-related genes.

Individuals with particular genetic predispositions and sensitivities are at a higher risk of experiencing respiratory symptoms, particularly chronic cough, as a result of widespread global air pollution. We investigated whether a genetic risk score based on cough-related single-nucleotide polymorphisms is associated with a cough rate greater than 24 h post-exposure to diesel exhaust, a model for traffic-related air pollution. We found that GRS was manufactured from 7 SNPs related to TRPA1, TRPV1, and NK-2R, which were correlated with cough count under closely monitored conditions. Following DE exposure and filtered air exposure, we found a significant, positive correlation between GRS and cough count after linear regression analysis. In summary, cough-related GRS was associated with a higher 24 h cough count in a controlled environment, meaning that people with a higher risk of experiencing cough may be more susceptible to respiratory disease regardless of their exposure.

The impact of the COVID-19 pandemic on air pollution: A global assessment using machine learning techniques.

Most countries introduced public health legislation in response to the COVID-19 pandemic, which resulted in restricted movement and a consequent improvement in air quality. Global comparison of pandemic-related declines in absolute pollution levels found in this book. In city- and pollutant-specific XGBoost models for over 700 cities, adjusting for weather, seasonality, and trends, non-linear relationships between atmospheric processes and daily ground-level NO 2, PM10, PM2. 5, and O 3 measurements were documented. As the weather variables that were most predictive varied across cities, city-level modeling enabled adaptation to the specific topography, urban morphology, atmosphere, and atmospheric conditions for each city, individually. Based on weather and established an ensemble for country-level pollution reductions, pollution forecasts for 2020 in the absence of a pandemic were forecast for 2020 in the absence of a pandemic. NO 2 did not fully recover to pre-pandemic levels in 2020, which was even higher. Ambient PM2. 5 pollution, which has serious health effects, has been minimized in China and India, with the bulk decreasing in China and India. Alternative transportation strategies could be a vital path to improved health outcomes in these countries since positive health outcomes may be limited to a certain degree by prolonged exposure to indoor air pollution. Several studies have shown that increases in O 3 values during initial lockdowns have been documented consistently. Nevertheless, our reports also found a subsequent decline in O 3 for several countries below what was expected based on meteorological conditions during the summer months. For the design of efficient mitigation plans to improve health outcomes, factors in periods of high O 3 levels are particularly relevant.

Impact of air pollution on outdoor cultural heritage objects and decoding the role of particulate matter: a critical review.

In most cases, cultural heritage material degradation results from chemical and physical changes in contact with the material's surface, which can cause chemical and physical changes. Two key elements of cultural heritage material degradation caused by air pollution, Atmospheric damage and soiling, are recognized as two key elements of depletion of cultural heritage materials due to air pollution. Soiling is the second phenomenon relating to cultural heritage information and PM pollution. In the past, it was believed that black carbon was the primary soiling agent, and that the change of the lightness would accurately determine the soiling. Despite the fact that several studies have investigated soiling and atmospheric damage separately, there is a similarity between these two processes. No systematic studies have been published on the synergy of soiling and atmospheric damage caused by atmospheric PM.

Links between chronic exposure to outdoor air pollution and cardiovascular diseases: a review.

Acute exposure to air pollution has an increasing risk of cardiovascular disease and cardiovascular disease. Nonetheless, the consequences of persistent exposure to air pollution on the circulatory system is also debated. In particular during the coronavirus disease 2019 case, we examine the associations of chronic exposure to outdoor air pollution with mortality and most common cardiovascular diseases. According to recent studies, persistent exposure to air pollution and cardiovascular disease has been shown to have a causal relationship. Noteworthy: For some chemicals that contain lead to adverse health effects, the risk of negative health effects is elevated for concentrations lower than the maximum values recommended by the European Union and Word Health Organization. Effective legislation and interdisciplinary cooperation are essential in helping air pollution reduction efforts to minimize exposure to air pollution and the development of effective air pollution reduction techniques.

Network approach reveals the spatiotemporal influence of traffic on air pollution under COVID-19.

However, the complicated link between traffic emissions and air pollution in cities and regions has yet to be established. Here, we explore the effect of traffic on air pollution by reconstructing a multi-layered complex network base on the traffic index and air quality index. In the first two stages and then declines, the effect of traffic on air quality in the BTH and CC regions becomes more noticeable, while in the other regions, where a significant impact occurs in phase 3. Our latest network-based framework gives a fresh perspective in the field of transportation and environment, and it might be useful in guiding the government to establish air pollution mitigation and traffic restriction policies.

A benefit allocation model for the joint prevention and control of air pollution in China: In view of environmental justice.

In the joint control and unsatisfactory effects of JPCAP, the inability of curiosity demands of many governance subjects in the new benefit allocation system results in widespread "free rider" activity. To ensure the synchronization between control costs and benefits based on environmental justice, this paper's pioneer is a benefit allocation scheme that JPCAP's benefit allocation scheme is being introduced. The interest demands of various control subjects and a benefit compensation scheme can be clarified by adopting an enhanced Shapley system, which exhaustively examines issues impacting environmental justice. The findings show that a benefit allocation model based on environmental justice will not only accurately assess the benefits of joint oversight, but also effectively achieve a synchronization of control spending and benefits. This research provides a quantitative and convincing theoretical basis for the benefit allocation of SO2 control, which may also be extended to other air pollution monitoring and practices.

Air Pollution and Chronic Kidney Disease Risk in Oil and Gas- Situated Communities: A Systematic Review and Meta-Analysis.

The aim of this systematic review and meta-analysis was to gather epidemiological evidence on the connection between long-term air pollution and kidney-related outcomes in oil and natural gas communities. Residents of more exposed or unprepared populations have an elevated risk of chronic Kidney Disease, lower eGFR, and elevated serum creatinine. The risk of hypertension and kidney cancer in the two groups were not significant different. Conclusion: We report an elevated risk of CKD and kidney disease in populations living near petrochemical plants, but from a limited number of studies.
