Application of INAA technique for analysis of essential and toxic elements in two Algerian plants Cynodon dactylon L. and Phragmites australis

Abstract

This study represents the investigation of major and trace elements in two indigenous plants, Cynodon dactylon (L.) and Phragmites australis, grown in the Ghardaia region of Southern Algeria. Using Instrumental Neutron Activation Analysis (INAA) technique, the research aimed to ascertain the content of essential and toxic elements in the aerial parts of these plants. Twenty eight elements as (Ag, As, Ba, Br, Ca, Ce, Co, Cr, Cs, Eu, Fe, Hf, Hg, K, La, Lu, Na, Nd, Rb, Sb, Sc, Se, Sm, Sr, Tb, Th, Yb and Zn) were analysis with INAA method. Given the scarcity of data regarding essential and toxic chemical elements in food within Algeria, the study focused on evaluating the content of these elements in two plant species commonly utilized by Bedouins in traditional medicine and as fodder, as well as by professionals for decontamination and water purification purposes. The concentrations of mineral elements observed in these plants were found to be in proximity to the minimum levels recommended by the Food and Agriculture Organization (FAO). The data obtained from this investigation are deemed applicable for Algerian food purposes, offering valuable insights into the elemental composition of these plants and their potential roles in traditional and practical applications.
