The Use of Biochemical Responses for Detecting the Impact of Gas Pollutant on Vigna sinensis L.

Abstract

Gaseous air pollutants in the troposphere, which is formed in the air under the influence of sunlight and lightning if the air contains nitrogen dioxide or sulfur dioxide even if at low concentrations. Conducted study the effect of gaseous air pollutants emitted by industrial city in Jeddah to evaluate the response of protein and fatty contents in plant Vigna sinensis L. and transplanted at distances (1-5,500,1000,1500,2000 meters) from industrial city, has been planting the seeds of the plant Vigna sinensis L. In the uncontaminated region far from industrial city, where we put three pots at each site contains five seeds, and has agriculture in the January 9, 2013, and left until the completion of the initial growth of leaves and then transported to the site of the study. The results showed that the concentrations of polluting gases around industrial city is going up during the study period, reaching 82 ppb for ozone and sulfur dioxide reached 28ppb while the nitrogen dioxide recorded 35ppb.The results also showed that there is a significant effect of these pollutants on protein content and fatty content ranging in plant leaves for protein (4.11 %) at a distance 1-5 meters, and (4.40 %) at a distance of 2000 meters. The fat content in experimented leaves lied between fat (3.13 %) at a distance and 1-5 meters (4.40%) at the distance of 2000 meters.
