20.5 Lymphohematopoietic study <strong>of</strong> workers exposed to benzene 1373<br />

benzene and have developed hematopoietic malignancies do not have changes in chromosomes,<br />

therefore the chromosomal changes cannot be used as a “genetic fingerprint”. Indeed,<br />

Irons’ publication in the Journal <strong>of</strong> Toxicology and Environmental Health 70<br />

concluded that the significance <strong>of</strong> these chromosomal alterations with respect to bone marrow<br />

damage or leukemogenesis <strong>of</strong> benzene is unclear. It is not possible today to determine<br />

whether leukemia is caused by benzene based on changes in chromosomes, specifically<br />

chromosomes 5 and 7. Smith from the University <strong>of</strong> California at Berkley, who is a leading<br />

authority in the biological markers <strong>of</strong> benzene exposure, opined that the data which supposedly<br />

suggest that one must have changes in chromosomes 5 and 7 to assume benzene causation<br />

is unreliable and obsolete. 71 In summary, while it is true that benzene and related<br />

products have been described with changes in chromosomes, DNA adducts, and cell cycle,<br />

by no means can they not be used as a diagnostic tool to address benzene causation or not.<br />
