Environmental impact of pollutants and the potential contribution to phytoremediation

Abstract

This 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.
