Location of chromosome aberrations in bone marrow cells of individuals exposed mainly to petroleum vapors

摘要

Structural chromosome aberrations were analysed in bone marrow cells from 15 tank cleaners exposed to organic solvents and other petroleum products, and sediments containing heavy metals, such as lead, mercury, arsenic and cadmium. Break points were identified by Giemsa banding in a total of 28 structural aberrations, 6 of which affected chromosome No. 9.
