biogeochemistry, backyard poultry eggs, trace elements


In the present study an attempt has been made for biogeochemical studies involving elemental distribution and interactions in backyard poultry eggs from Vemula barite mineralized area to determine their indicator characteristics and of their possible application in applied environmental geoscience. The samples of backyard poultry eggs of hen were collected systematically. Their physical properties like moisture, organic matter and ash content are determined which shows wide variations. Trace element analysis of these samples was carried out for Ba, Sr, Cu, Pb, Zn, Mn, Ni, Co, Cr, Fe Mg, and Al. the parameter Coefficient of Apparent of Organic Binding (CAOB) is calculated for each element for the eggs. Wide variations are observed in the distribution of chemical elements in backyard poultry eggs. Ba occupies first position in the sequence in all parts of the raw eggs both on ash weight and dry weight bases. The enrichment of Ba concentration in backyard poultry eggs may be due to the presence of barite mineral. Therefore backyard poultry eggs may ideally be used as tools for their possible application in mineral exploration. This study has given greater scope in biogeochemical orientation surveys, and in environmental studies
