Effect of indoor airpollution on Sansevieria trifasciata L
To evaluate the effect of some air pollutants on photosynthetic pigments and stress resistance parameters in Sansevieria trifasciata L., a completely randomized experiment with 7 treatments including control, benzene 50 and 25 ml.l-1 , acetone 50 and 25 ml.l -1 , ethanol 50 ml.l-1 and methanol 50 ml.l-1 with three replications. To apply the treatments, glass chambers with closed environments and same volume and area were prepared, each glass chamber containing valves for injection or air suction. One plant was placed in each chamber and the plant volume was measured and then certain concentrations of contaminants were injected into the chambers. The results showed that the evaluated air pollutants had a negative effect on the studied characteristics compared to the control, but acetone 50 ml.l-1 caused the most severe stress in censorship and stimulated the production of reactive oxygen species, thereby increasing proline production and increasing the plant's defense system increased protein levels. The photosynthetic activity of the Sansevieria plant also increased under the influence air pollutants. Accordingly, it seems that Sansevieria plant has a good resistance to the dominant air pollutants in the construction space of hospitals, laboratories, etc., which is recommended for these places.
