who have comparatively more industrial activities, it is considered that the accumulation of
arsenic might affect their hair loss to some degree. Recently air pollution, water pollution and
environmental pollution by soil have got worsen in the modern society due to the industrial
development. Above all industrial estates are more polluted compared to other areas by
emitted pollutants from not only industrial facilities but vehicles transporting raw materials or
products.
For this study heavy metal(Al, As, Ba, Be, Cd, Mn, Pb, Sb, Hg) contents in hair are
measured using ICP-MS (Inductivly Coupled Plasma-Mass Spectroscopy) to examine the effect
of the accumulation of heavy metal in hair by analyzing the heavy metal pollution level of
people with hair loss living near industrial estates, and SPSS 12.0 statistics program is used
to examine statistical significance of the experiments. Also independent-sample t-test is
conducted to know the difference of heavy metal content in hair between male and female,
and one-way ANOVA analysis is done to know the difference of heavy metal content in hair
depending on age group.
According to the analysis of the heavy metal content in hair depending upon sex shows
that there is a little difference between male and female considering only the average value
but statistically significant difference is only shown in beryllium(Be) and mercury(Hg). The
result means that heavy metal content difference depending upon sex is closely related with
one’s life style and life environment including dietary habits, drinking, smoking, occupation,
etc.
The comparative analysis of heavy metal content in hair according to sex shows that there
is no significant difference but the contents of arsenic (As), beryllium, cadmium, manganese,
lead, antimony and mercury are high in the forties, so heavy metals, which were accumulated
much within the people in their 40s with comparatively more industrial activities in heavily
polluted industrial complex areas, might affect their hair loss to some degree.
Especially in case of arsenic showing hair loss reported because of chronic exposure, there
is no significant difference but somewhat high contents are shown : men show 0.6344 ppm,
and women do 0.0378 ppm. And in the contents by age group, the contents are 0.0388 ppm
in the 30s, 0.6727 ppm in the 40s and 0.0458 ppm in the 50s. It means men in their 40s
with more industrial activities have comparatively high content. Therefore in case of men in
their 40s
