Aplastic Anemia in a Petrochemical factory Worker

摘要

A petrochemical worker with aplastic anemia was referred to our hospital. He worked in apetro- leum resin-producing factory and had been exposed to low-level benzene while packaging the powder resin and pouring lime into a deactivation tank. According to the yearly environmental survey of the working area, the airborne benzene level was approximately 0.28 ppm. Exposure to benzene, a common chemical used widely in industry, may progressively lead to pancytopenia, aplastic anemia, and leukemia.
