Abstract
Background:
Indoor air pollution is important environmental health problem. Nanotechnology is one of the most important methods to reduce the air pollution. The aim of this study to determine the effectiveness of nanotechnology for removal of toxic air indoor pollution by using Saudi myrtle plants treated with titanium dioxide.
Methods:
Experiments were conducted in the two academic departments of labs at public sector universities. Aplying titanium dioxide-containing growth media to at least one of a Myrtus communis plant root, stem, and leaf. Growing the plant in the growth media, a gel growth media, or both; exposing the plant to contaminant-containing air
Results:
It is found that the levels of formaldehyde, Volatile organic compounds and other pollutants were significantly reduced the concentration from 10% to 98% in air. The duration of the intervention from 4 hours to 8 hours, Air containing the concentration of NO2 SO2, formaldehyde, TVOCs and CO reduced from range of 0.3 ppm- 0.4ppm to range of 0.1ppm -0.3 ppm after exposure of Myrtus plant to ambient air and duration of the exposure is 4 hours to 8 hours.
Conclusion:
Application of Tio2 in green plant specially Mytrus Communis is a novel approach for reduction of concentrations of harmful gaseous toxic and carcinogenic air pollutants in indoor environment.
Removal of contaminants in indoor air by using green plant treated with titanium dioxide nanoparticles
