Chromosome aberrations in workers exposed to arsenic.
The occurrence of chromosome aberrations was studied in short-term cultured lymphocytes from nine workers exposed to arsenic at the Rönnskär smeltery in northern Sweden. In the smelter workers, 87 aberrations were found in 819 mitoses. The number of aberrations varied individually from 0 to 25 aberrations per 100 cells. In a control material 13 aberrations were found in 1012 mitoses. The freque...
متن کاملEryptosis in lead-exposed workers.
Eryptosis is a physiological phenomenon in which old and damaged erythrocytes are removed from circulation. Erythrocytes incubated with lead have exhibited major eryptosis. In the present work we found evidence of high levels of eryptosis in lead exposed workers possibly via oxidation. Blood samples were taken from 40 male workers exposed to lead (mean blood lead concentration 64.8μg/dl) and no...
متن کاملEnhanced Frequency of Chromosomal Aberrations in Workers Occupationally Exposed to Ionizing Radiations
The yield of chromosomal aberrations was analyzed in peripheral blood cultures to estimate the level of radiation exposure in workers from a radioprotection department. The subjects were exposed at low level dose rate (external exposure) to alfa, beta and gamma rays for time periods ranging between 7 and 34 years. We found a higher frequency of dicentrics and acentrics than in the control group...
متن کاملAnalysis of chromosomal aberrations in workers exposed to low level benzene.
Metaphase chromosome preparations were analysed as part of a larger study from a population occupationally exposed to benzene and compared with a control group. Forty eight of the 66 exposed individuals and 29 of the 33 controls had samples in which metaphase spreads could be evaluated. The incidence of chromosomal aberrations (particularly chromatid deletions and gaps) in the exposed group wer...
متن کاملAnalysis of chromosomal aberrations in shoe workers exposed long term to benzene.
Cytogenetic analysis of peripheral blood lymphocytes was used to compare 58 shoe workers (57 men and one woman) exposed to benzene and 20 subjects selected from the general population not exposed to particular mutagenic or carcinogenic agents (control group). Frequencies of damaged cells, including gaps, breaks, and rearrangements (acentric fragment, deletion, translocation) were scored for bot...
