There was a significant excess of deaths caused by major lymphomas in men employed in occupations where benzene and/or coal tar fractions are used. The increase in risk was limited to those who were 45 years of age and older at death, an observation which is consistent with the possibility that chronic exposure might be important. Evidence from other studies suggests that benzene may adversely affect the immunological system.
