A probable mechanism of remediation of metal within the soil The probable mechanism of adsorption of metals like Cr Hg and Cd based on complex formation with fatty acids algainate polysaccharides found in the algae and solid tea surface The incorporation of these two cost effective adsorbate play a crucial role in checking the mobility of metals. It is proposed that metal in a complex state doesn t moves in the free state to accumulate in the plants through false signal to the plant growth system. The mechanism of remediation of Cr3 based on adsorption of Cr3 on tea solid wastage within the soil where it was found that in the pot which contained thoroughly mixed tea waste with the garden soil shows soil stony structure and the plants of this pot was quite erect and more healthy as compared to plants with Cr3 and with no Cr3 . The available biochemical experimental data offered here that plants with mixed tea showed more tolerant morphological as well as physiological parameters. The remediation mechanism for the adsorption of heavy metal Cr3 using tea waste has been presented here showed that soft colloid and chemical components like palmitic acid of fatty acids group terpenes and di-Bu phthalate play a key role for complex forming with the metals reduced the mobility of metal in the contaminated soil and reduced the accumulation of Cr3 in plant tissues in the early stage of development of seedlings whereas the plants grown in a contaminated soil with seaweeds show swollen state of soil when watered and soil wet long time which indicate that seaweeds retained water in it and increases the water holding capacity which ultimately benefit to the soil under stress and supply water into the plants results to overcome the stress which results
