As affect human health, it is important to target tree planting in the role of reducing air pollution concentrations. capture capability of greening trees is associated with leaf morphology, while quantitative research is scanty. In this paper, the capture capability of 25 species in Beijing and Chongqing were examined by a chamber device. Groove proportion, leaf hair ...

En 1987, Santé Canada a publié ses Directives d''exposition concernant la qualité de l''air des résidences, qui ont établi des expositions maximales admissibles de longue et courte durées aux PM2,5 dans les habitations. Ces lignes directrices sont en train d''être révisées pour répondre à l''état actuel des connaissances scientifiques sur les effets sur la santé et l''exposition dans ...

20210201· In addition, the data also provided evidence that ZIF8 play a key position for PM capture during the air filtration process owing to its high surface area and positive charge. Thirdly, the higher thickness can slightly improve PM rejection rate but significantly made the transfer resistance increasing shown in Fig. 7c. After comprehensive optimizing, concern both of the PM removal ...

20200204· Masks can filter particles as small as microns – 10 times smaller than viruses, and much, much smaller than the cutoff. What’s more, they work surprisingly well, even while people are wearing them. Surgical masks don’t work as well as N95 masks, but they are cheaper and more readily available. This makes them useful alternatives when other masks aren’t available.

20190216· Up to now, it is still a significant challenge to fabricate the largescale flexible transparent smart window for highefficiency capture. Recently, a research team led by Prof. YU Shuhong from the University of Science and Technology of China (USTC) develops a simple solution based process to fabricate largearea Agnylon flexible transparent windows for highefficiency capture.

The US Environmental Protection Agency defines the AQI levels as follows: With regard to primary (healthbased) standards for fine particles (generally referring to particles less than or equal to micrometers (mm) in diameter, ), the EPA is revising the annual standard by lowering the level to micrograms per cubic meter (mg/m 3) so as to provide increased protection against ...

capture quantity, while no significantly positive correlations were found for leaf hairs and stomatal density. Broadleaf species are conducive to PM capture for their rich leaf morphology and have an edge over coniferous in PM capture per leaf area. However, coniferous had a larger PM capture capability per tree due to the advantage of a largeleafarea ...
