Environmental Pollution and Its Impact on the Accumulation of Certain Mineral Elements of Hair, Nail and Blood Samples

Abstract

The study estimated the concentration of some heavy elements. (Ni, Cr, Cu, Pb) In the hair and fingernails of some of the volunteers in several areas of Baghdad governorate, the study included 18 samples that differed between men, women and children as well as in the residential area and also varied in the nature of the work of the adult age groups of men and women, covering in differentwork. (Administrative, laboratory, out of work) The hair and nail were collected and subjected to a series of work, which included washing, drying and digestion  then analyzed by an atomic absorption spectrophotometer to calculated elements (Ni, Cr, Cu, Pb). The study also found that the content of the elements is high, giving a clear and reliable indication of the composition of the elements in the hair and fingernails and the amount of contamination. The researcher was unable to take blood samples for element tests due to the corona covied19 at the time when tests were carried out for the period from 1/2/2020 to 1/12/2020.
