Title: Animal Hair as a Bio-Indicator of Heavy metals Pollution in Semi-Arid Areas at South of Egypt
Author: M.N.Rashed., M.E.Soltan.
Abstract: Animal hair is a good bio-indicator of environmental pollution with heavy metals. Hair of sheep , goats and camels were collected as well as grazing plants and soil from three different environmental semi-arid areas at south of Egypt ( Aswan city, El-Allaqi desert and Haliab & Shalatin area) . The concentration of heavy metals Pb, Mn ,Fe, Cd and Cu were determined in hair, soil and plant samples by atomic absorption spectroscopic analysis . The results revealed that for all hair under study , the sheep ,goat and camel hair from Aswan city exhibited the higher levels of Pb ,Mn and Cd than those from the deserts (El- Allaqi and Haliab & Shalatin desert) and this related to the high concentrations of these elements in the plant feeds and soil of Asawn city resulted from input pollution from industries . Desert animal hair contained higher levels of Fe and Cu than those from Aswan city as the results of the cycle of those metals from parent rocks to grazing plant and soil and finally to the animals. Using statistical analysis of cluster analysis ,multiple regression analysis and factor analysis we obtained information concerning relations among the heavy metals in animal hair ,plant and soil.
