Impact of Environmental Pollution by Spent Oil Levels on Leaf Anatomy of Eruca Sativa

Abstract

Pollution is the quantitative change that occurs to one or more of the elements of the environment that would harm the life of the living organism and weaken the ability of the environment to continue its production. The current research was carried out to study the impact of spent engine oil pollution on some anatomical leaf characters of Eruca Sativa. The pots of sandy soils were contaminated by adding spent engine oil levels of 0.0, 2.5, 5.0, 15.0 and 30.0 ml.3kg-1. From the results, it is noted that a convergence and a slight decrease in the thickness of the cuticle layer of the upper and lower surface of the leaf at the levels of added oil 1.5 and 2.5 ml.kg -1. It was observed, that there was a relative decrease in the thickness of the upper and lower epidermal cells layer at the low levels of addition, with the increase in the decrease in thickness with the increase in the levels of spent oil. And it was found that a clear increase in the thickness of the palisade layer with the increase in the levels of spent oil addition compared to the thickness of the layer in the leaves of plants grown in soil with an addition level of 0 ml.kg-1. It is clear that the dimensions of the stomata for the upper and lower leaf surface of the plant leaf increased and took a behavior that corresponded to the increase in the levels of spent engine oil.
