Abstract

In current day, the land for development has been greatly exhausted, and it is caused mainly by the consumption of metals spillage to the surface soil. However, the code for metals extraction from the surface soil has not yet established. Thus, it is acknowledged that the purpose of this research is to conduct the main reason of suitability and efficiency of the current trends of high costing in conserving the environment by plant, such as shrub on surface soil to a much lesser expenses. The technique is to actually curb the contamination by using the technology of phytoremediation in real situation of containing; by means of removing, relocating, stabilizing or even perishing the five specific contaminants of Cadmium (Cd), Chromium (Cr) and Lead (Pb) in Tagetes erecta under a conserved environment of this study. The purpose of this studying is to determine Tagetes erecta availability of treating the contaminated surface soil of the five types of metals. The analysis will be using digestion procedures of the Environmental Protection Agency (EPA) mild digestion in hot plate for metals analysis of using Atomic Absorption Spectroscopy (AAS) in determining the metals in interest. The leave have been recorded with the increasing polar of absorption upon Lead < Cadmium < Chromium at the concentration of 5594 ug/g < 741 p.g/g < 170 ng/g, while the concentration of the stem has the value of 2824 Lig/g < 204 ug/g < 100 Lig/g. Yet, the content of root has Lead < Chromium < Cadmium concentration as the orientation, whereby, the concentration of the elements as 8116 iig/g < 250 ug/g < 156 Lig/g. The category of the highest metal absorption to the Tegetes erecta rallied on Lead < Cadmium < Chromium as of 91%<6%<3%.
