Since the release of the initial 1989 study, titled A study of interior landscape plants for indoor air pollution abatement: An Interim Report, [6] further research has been done including a 1993 paper [7] and 1996 book [8] by B. C. Wolverton, the primary researcher on the original NASA study, that listed additional plants and focused on the removal of specific chemicals.
The idea that a simple houseplant could “absorb” VOCs and make the air cleaner was good news, and many publications, including Good Housekeeping, used this study as a basis to recommend “the ...
The idea of plants having purifying powers comes from the 1989 Clean Air Study conducted by NASA, which found that certain plants removed health-harming pollutants from indoor environments. But ...
Since indoor air pollutants can adversely affect human health, it is important to have real-time indoor air quality assessment/monitoring system that can help not only in the improvement of indoor air quality but also help in detection of leaks, spills in a work environment and boost energy efficiency of buildings by providing real-time ...
Although houseplants are commonly considered to have an active, positive effect on indoor air quality, much of the non-academic reporting on the subject is based on experiments involving the removal of volatile organic compounds (VOCs) from the air, the evidence for which is unclear. [43]
Improve the air quality in your home the natural way with the best air purifying houseplants, like the peace lily, the bamboo palm, and English ivy, and more!
Vapour pressure-deficit, or VPD, is the difference (deficit) between the amount of moisture in the air and how much moisture the air can hold when it is saturated. Once air becomes saturated, water will condense to form clouds, dew or films of water over leaves. It is this last instance that makes VPD important for greenhouse regulation. If a ...
Indoor and outdoor air are sampled, and their mold spore concentrations are compared. Indoor mold concentrations should be less than or equal to outdoor concentrations with similar distributions of species. A predominant difference in species or higher indoor concentrations can indicate poor indoor air quality and a possible health hazard. [8]
