Abstract: Air pollution is one of the biggest and serious challenges facing our
planet nowadays. In fact, the need to develop models to predict this issue is
considered so crucial. Indeed, our work aimed at building an accurate model to
predict air quality of US country by using a dataset collected from connected
devices of internet of things (IoT)...

... air quality index (AQI) can be defined as a number used by government agencies to report daily air quality in order to communicate to the public how clean or unhealthy the air is (Air Quality Index, no date). As shown in Figure 3, each AQI category has assigned to a specific colour and the corresponding health warnings. In fact, knowing what the colour codes mean may help people protect their health during air quality levels associated with low, moderate, high and very high health risks. ...

Clouds significantly affect the Earth's radiation budget and play a critical role in atmospheric sulfate formation. The pathways of S(IV) oxidations have recently caused a controversial attention under severe haze episodes due to the variable acidity and water content in aerosol particles. In this study, a total of 158 cloud samples were collected...

Since the industrial revolution, human activities have dramatically changed the nitrogen (N) cycle in natural systems. Anthropogenic emissions of reactive nitrogen (Nr) can return to the earth's surface through atmospheric Nr deposition. Increased Nr deposition may improve ecosystem productivity. However, excessive Nr deposition can cause a series...

Therefore, BDA is gradually used in forecasting air pollutant concentrations (Alaoui et al., 2019;Al_Janabi et al., 2019;Xu et al., 2020) and other research fields. ...
The Assessment and Appraisal Method for Ecological Construction Targets (the Method) was promulgated in 2016, which provided a concrete instruction for China’s air pollution control and established an explicit standard for reducing air pollutant concentration. This study implements a sharp regression discontinuity (RD) design and makes an assessment on air quality control effectiveness of the Method based on the high-volume big data acquired from 173 cities in China. The results show that the Method has significantly improved air pollution control on the overall air quality index (AQI) and reducing concentrations of PM2.5, PM10, SO2, NO2, and CO across the country in the observation periods. However, no reduction effect was observed for O3. The robustness tests support the conclusion as well. Besides, the heterogeneity analysis illustrates that the policy had a significant short-term treatment effect in East, South, Central, North, Northwest, Southwest, and Northeast China. However, the Method’s effect is found to decline over time either nationwide or regionally according to the persistence analysis. Therefore, this article puts forward several suggestions regarding the formulation of long-term regulations for air pollution control, the transformation of the growth model for sustainable development, and optimization of the incentive system for improved pollution control and prevention.
Human exposure to air pollution is a major public health concern. Environmental policymakers have been implementing various strategies to reduce exposure, including the 10th-day-no-driving system. To assess exposure of an entire population of a community in a highly polluted area, pollutant concentrations in microenvironments and population time-activity patterns are required. To date, population exposure to air pollutants has been assessed using air monitoring data from fixed atmospheric monitoring stations, atmospheric dispersion modeling, or spatial interpolation techniques for pollutant concentrations. This is coupled with census data, administrative registers, and data on the patterns of the time-based activities at the individual scale. Recent technologies such as sensors, the Internet of Things (IoT), communications technology, and artificial intelligence enable the accurate evaluation of air pollution exposure for a population in an environmental health context. In this study, the latest trends in published papers on the assessment of population exposure to air pollution were reviewed. Subsequently, this study proposes a methodology that will enable policymakers to develop an environmental health surveillance system that evaluates the distribution of air pollution exposure for a population within a target area and establish countermeasures based on advanced exposure assessment.
