Item Potential plastic digestor of Euphorbia Tirucalli(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) SILVA, Simone da; LEITE, Jandecy CabralNatural products that cause oxidative stress and local corrosion are of interest in the degradation of persistent materials such as plastics. This chapter evaluated the corrosive and shrinkage physicochemical action of aqueous extracts of Euphorbia tirucalli on polypropylene (PP-5) subjected to temperature variations. Despite observations regarding potential practical applications, raw latexes from tested geographic regions did not chemically digest isopropylene. It is suggested that effective plastic digestion requires the presence of a specific endophytic fungus. Further tests will be conducted to investigate phytoremediation mechanisms.Item Environmental impact of pollutants and the potential contribution to phytoremediation(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) SILVA, Simone da; LEITE, Jandecy CabralThis chapter revisited an experiment that evaluated elicitors for the germination of Vigna unguiculata (Cowpea Beans): the plant extract of Euphorbia tirucalli, the ultra-diluted and dynamized solution of Sulfur 5CH, and the two in combination. In 2017, significant seed engorgement and ammonia-like odor exudation suggested involvement of the sodium/potassium pump, thiol group detoxifying enzymes, and nitrogenous oxidative stress pathways. Given recent literature linking thiol groups to mercury phytoremediation, the study discusses E. tirucalli as a potential hyperaccumulator, considering mechanisms such as phytoextraction and phytovolatilization of pollutants.
