Plants improve air quality through respective mechanisms : they absorb carbon paper dioxide and release oxygen through photosynthesis, they increase humidity by transpiring water vaporization through microscopic flick pores, and they can passively absorb pollutants on the external surfaces of leaves and on the establish root-soil organization. But plants are normally selected for indoor use not for their air-purifying abilities but for their appearance and ability to survive while requiring fiddling maintenance. “ For most of us plants are fair a cosmetic component, something aesthetic, but they are besides something else ” says Brilli.

amazingly fiddling research has been done to quantify the effects of different plant species on indoor air travel quality. NASA performed pioneering work in the 1980s, but they relied on a simple experimental border on ; studies with more sophisticate, advanced research methods and modeling have not so far been conducted. farther research is needed identify the characteristics of the highest-performing plant species in indoor environments, including their morphology ( i.e. leaf shape and size ), anatomy, and physiology ( i.e., CO2 assimilation rate ). According to Brilli, such studies could show how to “ optimize the use of plants indoors, in terms of how many plants per square meter we need to reduce air befoulment to a certain level. ”
research is besides needed to understand plant microbiomes : the populations of microorganisms ( bacteria and fungi ) that be with plants both in the land and on leaf surfaces. This microbiome participates in the removal of airborne pollutants, but the contribution of different microbial species to removing pollutants is presently unknown. Some microbiomes could besides have negative effects on homo health, including triggering allergies and lung inflammation problems, so knowing how to identify and avoid those will be important .
Brilli and colleagues do not envision plants replacing modern inflame, ventilation, and air travel conditioning systems, but they argue that integrating plants with smart sensors networks and early computerize technologies could make those air cleaning more cost-efficient and sustainable. Says Brilli, “ plant physiologists should work with architects to improve the park indoors. ”
