Investigation of Some Elements Concentrations and Distribution in Body parts and Organs of Japanese Quail Cotornix japonica

The presence, concentration and distribution of 42 trace and ultra-trace elements in addition to rare earth elements (REE), yttrium(Y) and Thorium (Th) were analyzed using Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) in different body parts and organs of Japanese quail Cotornix japonica as a laboratory animal model. Twenty one of the investigated elements were below detection limit while the rest of the investigated elements varied in amount and distribution relative to organs and parts in which they were investigated. The existences, concentrations and distributions of thallium (Tl) and europium (Er) are recordedin a higher living species in the present work. The present work also documented the presence, concentration and distribution of Thulium (Tm) a living organism. The recorded concentrations and distributions of various elements may be related to their roles in structures and functions of organs in which they were distributed. From the present findings, a better classification of elements according to distribution and concentration levels in individual organs is recommended. It is also recommended to investigate the existence of Tm, Tl, and Er in other living species and a further investigation of the role of Tm, Tl, and Er in structure and metabolism of Cotornix japonica parts and organs in which they were detected.
