Abstract:
In this study, scalp hair samples were collected from workers working in
workshops and perfume factories in Omdurman area where there is an expectation
of exposure to environmental pollution. The hairs content determination was
performed using X-ray fluorescence (XRF), Laser-Induced Breakdown
Spectroscopy (LIBS) and Inductively Coupled Plasma-Atomic Emission
Spectroscopy (ICPE) to assess elements (Mn, Cu, Zn, Hg, Pb, Sr and Fe) due to the
adoption of hair tissue scalp as a biological indicator of toxic elements in the
human body. An alternative approach of hair sample treatment was implemented
by grinding in liquid nitrogen at temperature of 77oK to form a dry weight samples
in fine powder mode. In a comprehensive assessment the results have been
compared with the results of International Atomic Energy Agency (IAEA) as a
reference value. Data obtained by using three ways: (XRF), (LIBS) and (ICPE) to
make sure the values extracted from this study for contributions to the analysis of
pollution factors resulting from work in industrial areas. The percentage of
manganese Mn contamination was high in each of the samples (No:11, No:18 and
No:C9), as the sample No:11 average concentration 15.499 ppm, the sample No:18
average concentration 13.31 ppm and the sample No: C9 average concentration
12.47 ppm, while the reference value equals 9.6 ppm. The pollution by copper Cu
was top on the sample No: 12 with an average value of 56.43 ppm, while the
reference value is 17.6 ppm. The zinc Zn component was highest in the sample
No:18 with an average value 370.3 ppm, while the reference value equals167 ppm.
The pollution by mercury Hg was top on the sample No: 12 with an average value
of 39.36 ppm. The largest proportion was enough strontium Sr component of
pollution category No:18 with an average 7.364 ppm, while the reference value
equals 4.97 ppm. The pollution by iron Fe was top on the sample No: B24 has an
average value of 205.14 ppm, while the reference value equals 123ppm.
