“…Scholars from different countries carried out some types of corresponding measures and research to solve the existing environmental pollution problems at the same time, and to create a good indoor and outdoor environment [14][15][16][17][18][19][20][21][22][23][24][25]. For example, plants reduced many pollutants such as volatile organic compounds, carbon monoxide, nitrogen and sulfur oxides, particles, formaldehyde, and heavy metals [14,15].…”

High concentration of PM 2.5 has seriously affected people's daily lives in recent years. It is necessary to analyze PM 2.5 and the correlations with other pollutants in winter. Data presented in this paper were obtained from monitoring stations from 2016 to 2018. Attention was fixed on PM 2.5 and its monthly and daily variations in winter. Furthermore, the correlations between PM 2.5 and CO, SO 2 , NO 2 , O 3 and PM 10 were studied. The results showed concentrating PM 2.5 was roughly consistent with the monthly and daily trends. It was January>December>February>November>March. The mass concentration ranges of PM 2.5 before and after the adjustment of heating energy structures were 64.5-184.1 μg/m 3 , and 86.4-140.1 μg/m 3 , respectively. The average concentrations of PM 2.5 were 135.5 μg/m 3 , and 109.1 μg/m 3 , decreased by 26.4 μg/m 3. PM 2.5 /PM 10 was changed from 64.6% to 62.6%, reduced by 2%. The linear correlation analysis revealed a strong correlation between PM 2.5 and CO, SO 2 , NO 2 , and PM 10 , but a negative correlation between PM 2.5 and O 3. Two multiple linear regression models on the pollutants were established, respectively. This study helps understand the concentrating distribution of PM 2.5 and other pollutants in winter. It will provide some useful references to control air pollution for some cities, which have a similar type of heating energy structure.

“…Some results had been achieved, and the main focus were on composing particulate matters [14], the limits of the standards [15], regional studies [16], human health and the correlation between particulate matters and other pollutants [17]. In addition, more scholars were also focusing on the research and development of new air filter materials to control the concentration of particulate matter [18,19]. Also some types of corresponding measures and research were carried out to solve the existing environmental pollution problems [20][21][22][23][24][25].…”

IntroductionWith improved living conditions, people gradually pay more and more attention to the problems which were caused by air pollution [1]. The concentrations of particulates and gassy pollutants in the atmosphere were all seriously exceeded. Such as PM 2.5 , PM 10, sulfur dioxide (SO 2 ), nitrogen dioxide (NO 2 ), carbon monoxide (CO), and ozone (O 3 ) [2]. They would not only lead to a serious decline in atmospheric visibility, but also they would cause many problems to people's travel and transport at the same time [3]. PM 2.5 was usually referred to as particulate with an average aerodynamic diameter of less than 2.5 μm, and they did not settle automatically [4]. PM 2.5 was more likely to carry more viruses or bacteria with its small particle sizes and large specific surface area. It would bring different degrees of harm to human health, even death [5][6][7].

“…Therefore, the selection of the material of the fresh air pipes was based on comprehensive factors in using. Air filters fibers were added to the front of the fresh air filtration systems, which could effectively block the deposition of particles in the pipelines, and it reduced the frequency of pipeline cleaning and the quality of air supply [39][40][41].…”

With the widespread popularity of fresh air filtration systems, the pipes materials have become one of the important parameters that affect the overall performances of the fresh air systems. In this paper, an experimental study on the deposition of particulate matters on two commonly used pipes materials (PVC and PE) in the market was tested, and conducted an in-depth analysis of its influencing factors. The results showed that the deposition rates of particulate matters in the PVC pipe increased with the increased of the inlet velocity, and the deposition rate reached the maximum at the velocity was 4.0m/s. While the deposition rates of particulate matters in the PE pipe were increased first and then decreased with the increased of the inlet velocity, and the deposition rates reached the maximum at the velocity was 3.5m/s. The PM values deposition rates showed the pipe systems of PE were higher than that of PVC. With the increased of the particle sizes, the tends of deposition rates increased gradually. There were big differences in the deposition rates of particle sizes of less than 1.0?m, and the largest difference was 0.615?m, with 8.44%. Therefore, reasonable pipeline materials should be selected comprehensively according to actual need in the process of pipeline installation and use. It would provide a useful reference value for the selection of pipeline materials in the fresh air filtration systems in the post-epidemic era.
