Deze video is erg belangrijk voor mensen
die veel binnen leven/werken. Deze 3 planten zuiveren de lucht en zorgen voor voldoende
zuurstof en zouden eigenlijk in ieder kantoor, schoolklas of slaapkamer moeten staan.
Zeker als je gevoelig bent op je luchtwegen. Geef aub deze video door aan de mensen die je
Onderzoeker Kamal Meattle toont 3 gewone
huisplanten die op specifieke plekken in huis of kantoor gebruikt kunnen worden als
natuurlijke zuiveraars van de binnenlucht. De planten zijn zelfs in staat spaanplaatgassen
(formaldehyde) af te breken.
The first list of air filtering plants was
compiled by NASA as part of the NASA Clean Air Study, which researched ways to clean air
in space stations. As well as absorbing carbon dioxide and releasing oxygen, as all plants
do, these plants also eliminate significant amounts of benzene, formaldehyde and/or
trichloroethylene. The second and third list are from Dr. B.C. Wolverton's book and focus
on removal of specific chemicals.
The toxic gas formaldehyde is contained in
building materials including carpeting, curtains, plywood, and adhesives. As it is emitted
from these sources, it deteriorates the air quality, which can lead to "multiple
chemical sensitivity" and "sick building syndrome", medical conditions with
symptoms such as allergies, asthma, and headaches. The prevalence of formaldehyde and
other volatile organic compounds (VOC) is greater in new construction. Researchers are
studying the ability of plants to reduce formaldehyde levels in the air. A study led by
Kwang Jin Kim of Korea's National Horticultural Research Institute compared the absorption
rate of two types of houseplants. The results of the experiment on Weeping Fig (Ficus
benjamina) and Fatsia japonica, an evergreen shrub, were published in the Journal of
American Society for Horticultural Science.
During the study, equal amounts of
formaldehyde were pumped into containers holding each type of plant in three
configurations: whole, roots-only with the leafy portion cut off, and aerial-only, with
the below-ground portion sealed off, leaving the stem and leaves exposed. The results
showed the combined total of aerial-only and roots-only portions was similar to the amount
removed by whole plants. Complete plants removed approximately 80% of the formaldehyde
within 4 hours.
Dr. B.C.Wolverton's first book, "How
to Grow Fresh Air", is available in book stores or directly from Penguin books, New
The book thoroughly discusses the problems
associated with poor indoor air quality and provides a natural solution through the use of
Plants are the lungs of the earth. This
revolutionary guide, based on 25 years of research by NASA, shows how common houseplants
can combat sick building syndrome and cleanse the home or office of common pollutants.
Complete plants removed approximately 80%
of the formaldehyde within 4 hours. Control chambers pumped with the same amount of
formaldehyde, but not containing any plant parts, decreased by 7.3% during the day and
6.9% overnight within 5 hours. As the length of exposure increased, the amount of
absorption decreased, which appeared to be due to the reduced concentration of the gas.
