Alsaffar Market Research and Consumer Protection center/University of Baghdad/Baghdad/Iraq alsaffar2005@mracpc.uobaghdad.edu.iq 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. Key words: Chromium, copper, lead. Introduction: Studies and research have examined environmental pollution, whether of air, water or soil, because of its gravity and direct association with many diseases affecting humans as a result of exposure to environmental pollutants. Most States are therefore keen through research and studies to enact regulations and legislation to protect people from these pollutants. One of the most important environmental pollutants is car exhaust, industrial waste and human waste itself. Technical development has also contributed to increasing pollution rates despite its benefits to humanity. The most dangerous environmental pollutant is industrial development at the global level. Many local and international studies have established heavy metal contamination of the soil. Importance of research: The importance of research lies in the possibility of adopting hair and fingernails to calculate the heavy elements and their relation to environmental pollution because of the difficulty in taking blood samples from some patients for fear of needle prick or the difficulty in taking a blood sample because of the spread of a particular disease or disease pandemic that we experienced at the time of the current research(1). Study sample: The study covered 7 men (3 in laboratory work and 4 in administrative work), 8 women (6 in administrative work and 2 housewives) and 3 children less than 8 years of age. Equipment used: The incinerator, acid for digestion, and the AA- 7000 atomic absorption spectrophotometer were used by Shimadzu (Japan). Hair analysis: Hair is strong evidence where it is not damaged over time. The victim or criminal can be identified. The hair fingerprint evidence was taken before the courts in 1950, where any hair sample placed in the heart of a nuclear reactor to be released into introns would turn all rare hair elements into radioactive materials, even if the material was part of a billion parts of the gram. In each hair there are 14 rare elements and one in a billion people sharing nine of them. In 1895 spectroscopy was used by spectrometers that shoot light at the material to be analyzed by identifying black lines that are the absorption lines of the spectrum colors. Each material has its own lines through which it is identified. Hair, like other industrial and natural fibers such as nylon or cotton, can produce vague forensic results. However, all fibers consist of a very complex and long chain of molecules. But parts of it can be identified under normal optical, electronic or infrared microscopes. The colors of these fibers can also be compared to the computer. The standard hair sample is examined by way of removal to contain the hair affinity(4).
