Optimization Tests of Antagonistic Interaction between Lead / Iron and Lead / Zinc, IN-VITRO Investigations on the Plant: PHASEOLUS VULGARIS

Lead pollution is a global problem, currently under a general awareness. Recent research has confirmed the impact of this pollutant in exposed organisms. Emission sources of lead are multiples and more particularly the emissions of exhaust gases of vehicles because of its use as Tetraethyl lead  Pb (C2H5)4 was the main constituent of antiknock agents added to gasoline to increase the octane rating.  Knowing that exposure to lead causes lead poisoning, the reflection on the modalities of detoxification needed. It is in this vein that we try to offer our looking for away to detoxification by means of the interaction between lead and iron on one side and lead and zinc of another side of the plant in vitro “PHASEOLUS VULGARIS”. In order to determine the most reliable results in terms of limitations of the toxic effects of lead exposure on the plant in other words antagonism. The choice of iron and zinc is justified by their biological role, in addition they are desired item
