Abstract |
: |
This study was conducted during summer, autumn, winter and spring of 2009-2010, to study the effect of industrial locations, seasons, plant age and washing of Date palm, Neem and Conocarpus plant species. The obtained results showed that the highest concentration of the toxic and microelements in/on the leaves of Date palm tree were produced in the location (2) and (3) in the industrial zone. Means of the toxic elements were 2.35, 3.25, 4.29, 32.10 for Cd, Ni, Cr and Pb, respectively. Hada Al-sham was the lowest in the previous elements. Spring season produced the highest toxic and microelement concentration followed by winter season in the three plant species. The 4 year age trees and non washed produced the highest both metals. Highest significant effects were pronounced for the 2 factor interactions between (season X location), (Season X plant age), (Location X plant age) and (plant age X washing) on the toxic and micronutrient concentrations. The minimum values of the leaf area in Date palm, and Neem trees were detected under the effect of the location (2) in the 4 year age trees, while in conocarpus, was under the location (3). The location (2),(3) and (4) in the industrial zone significantly adversely affected nitrogen and protein content in the three species leaves. The highest suspended solid matter in air was 495 µg/m3 produced in the spring in the location (2), and the highest values of the NO2 (83 µg/m3), SO2 (47 µg/m3) were in location (3) in winter, while the highest CO (1.06 mg/m3) was found in location (1) in winter comparing the study results with the WHO, FAO and Saudi Standards, the locations (2) , (3) and (4) in the industrial Zone in Jeddah were higher values than the standard toxic limit concerning all toxic and microelements polluted the plants. Also, the previous three locations had suspended solid materials over the highest standard limits. |
