“…[4][5][6][7][8][9] Extensive research works from biochemistry and biomedicine areas have demonstrated that haze may bring harm to human's health, 10 including increasing the risk of adult mortality, preterm birth, and causing ocular surface diseases, Alzheimer's disease, and so on. 8,[11][12][13] Haze may result in welfare loss and a serial of social problems as well. Taking China as an example, haze may impact China's agricultural production and decrease the satisfaction of international tourists, lead to an outflow of the labor force, and even enhance the risk of mood driving.…”

Extreme haze was often observed at many locations in Beijing–Tianjin–Hebei region within several hours when they occurred, which is referred to as extreme co-movements and extreme dependence in statistics. This article applies tail quotient correlation coefficient to explore the temporal and spatial extreme dependence patterns of haze in this region. Hourly PM2.5 station-level data during 2014–2018 are used, and the results show that the tail quotient correlation coefficient between stations increases with month. Specifically, the simultaneous extreme dependence was strong in the fourth season, while the haze was severe. In the first season, while the haze was also severe, the extreme hazes only show strong co-movements with a time difference. These observations lead to the study of two special scenarios, that is, the concurrence/extreme dependence of the worst extreme haze and its lag effects. City clusters suffering simultaneous extreme haze or with certain time difference as well as the most frequently co-movement cities are identified. The extreme co-movements of these cities and the reasons for their occurrences have strong implications for improving the PM2.5 joint prevention and control in the Beijing–Tianjin–Hebei region. The importance of lag effects is also reflected in the precedence order of the extreme haze’s appearance. It is especially useful when setting the mechanism of the early warning system which can be triggered by the first appearance of extreme haze. The precedence orders also avail in investigating the transmission path of the haze, based on which more precise meteorological models can be made to benefit the haze forecasting of the region.

“…On one hand, NO x comes from the natural factors of nitrate caused by decay of organism after biological death and plant straw-burning as well as in the lightning process; on the other hand, it stems from the artificial factors, for instance, iron and steel smelting; petroleum cracking and coal-based fossil fuel power generation; fuel vehicle exhaust emissions [1,2]; and NO x decomposition under the action of soil microorganisms, which is caused by the large amount of nitrogen fertilizer applied in farmland [3,4]. The emission of toxic waste gases has resulted in a significant increase in the content of NO x in the atmosphere, which is damaging to human organs, such as the heart and lungs, and reducing the body's immunity [5], combining with volatile organic compounds to produce ozone [6], making the human body susceptible to respiratory diseases such as coughs, sore throat, and bronchitis [7,8]; it can also lead to premature birth [9], severely inhibiting photosynthesis, and thus affects plant growth and oxygen conversion [10,11]; but, at the same time, produces photochemical smog [12,13] and acid rain [14]. Furthermore, it forms aerosol with SO 2 , dust, and water vapor, then produces PM2.5 and other small particle size air pollution suspensions, namely, haze, which cause serious air pollution worldwide [15,16].…”

Nitrogen oxides (NO x ) represent one of the main sources of haze and pollution of the atmosphere as well as the causes of photochemical smog and acid rain. Furthermore, it poses a serious threat to human health. With the increasing emission of NO x , it is urgent to control NO x . According to the different mechanisms of NO x removal methods, this paper elaborated on the adsorption method represented by activated carbon adsorption, analyzed the oxidation method represented by Fenton oxidation, discussed the reduction method represented by selective catalytic reduction, and summarized the plasma method represented by plasma-modified catalyst to remove NO x . At the same time, the current research status and existing problems of different NO x removal technologies were revealed and the future development prospects were forecasted.Catalysts 2019, 9, 771 2 of 39 adsorption, oxidation, reduction, and plasma methods. In view of these attentive findings, adsorption method uses recyclable solid adsorbent material to adsorb NO x from flue gas through microporous structure, remarkably, environmentally friendly, no secondary pollution, and energy-saving and -efficient features make it stand out [18][19][20]. The oxidation process is a method that oxidizes NO into NO 2 or N 2 O 3 with high solubility under the action of an oxidant that is then absorbed by water or alkali solution. The process is simple and cost-saving, and is widely used in the wet flue gas denitrification process with relatively low cost and high removal efficiency of NO x ; except that the oxidized NO and SO 2 can be removed simultaneously to produce high value-added products [21][22][23]. The reduction method has the characteristics of high efficiency, cleanliness, and mildness; NO x removal can be realized at low temperature at present [24][25][26]. The plasma method is used to modify the surface of the catalyst, the dispersion of active species can be improved by plasma treatment, and the stability and low temperature activity of catalyst can be improved [27,28].Seldom, if ever, does a comprehensive article to introduce the current situation and treatment methods of removing NO x . In this paper, we tried to renovate, classify, and summarize the significant perspectives and most relevant findings reported in recent research articles and earlier reviews generalizing the mechanism analysis and research progress of NO x removal by adsorption, oxidation, reduction, and plasma methods, which can provide means for promoting the technological progress of pollution prevention, maintaining healthy development of factories continuously, studying the methods of removing NO x deeply, and mastering different technologies of removing NO x , as well as providing guidance for controlling the emission of NO x from motor vehicles such as diesel, gasoline, and so on. In order to improve the environmental quality and save the ecological environment, this paper further provides a convenient, low-cost, efficient, and economic guidance line.

Developing fetus is connected to the mother by placenta to receive oxygen and nutrients. Maternal exposure to ambient air pollution not only affects maternal health but also provides a pathway for many toxic pollutants to cross the placental barrier and interrupt biochemical milieu. There are numerous scientific studies available describing possible negative health impact of air pollutants on reproductive health, pregnancy outcomes and fetal development yet no toxic effect is available recently. Studying the pollutants exposure effect on fetal development is crucial for the underlying mechanism between prenatal exposure and pregnancy outcomes. Present review meticulously provides the compiled data of 40 most recent studies with possible action mechanism of air pollutants on pregnancy outcomes and fetal development to find a better solution to exterminate or reduce the problem.
