In Korean industries, an
excessive risk of hematopoietic diseases because of
relatively high past exposure to benzene has been reported
[9]. Apart from direct occupational exposure,
nonoccupational population around chemical factories
and other occupational sites may also undergo indirect
exposure [10]. Thus, occupational exposure hematotoxicity
[11] and other blood disorders such as blood
cancer (leukemia), aplastic anemia, and dysplastic bone
marrow conditions are common results of exposure to
aromatics such as benzene [12], screening of which can
be done easily by complete blood counts.
