Nonrandom distribution of breakpoints in the karyotypes of workers occupationally exposed to benzene.
نویسنده
چکیده
The distribution of the breakpoints in the karyotypes of workers occupationally exposed to benzene was tested. Fifty-six workers exposed to benzene were investigated cytogenetically. A significant increase in chromosome aberrations was observed. The distribution of the breakpoints in the karyotypes of examined workers was significantly nonrandom (p less than or equal to 0.001). The breakpoints accumulated mainly on chromosomes 2, 4, and 7.

Background and objective: Benzene is one of the main pollutants in air and one of the most extensive chemical compound used in both natural and industrial processes. Benzene exposure leads to the most dangerous adverse health effects, particularly blood cancer. The aim of this study was to evaluate the gas station workers’ exposure to benzene by measuring benzene in breathing air and urinary tr...
متن کاملAssessment of Thyroid Function in Workers Occupationally Exposed to Gasoline and Paint Products in Anambra Central of Nigeria
Hydrocarbons (benzene, toluene, ethyl benzene and xylene (BTEX) found in gasoline and organic solvents are ubiquitous in the environment, and are known to have toxic effects in human system. This study therefore investigated the thyroid function of workers occupationally exposed to gasoline and paint products using TSH, T3 and T4 as markers. A total of 162 subjects were recruited for this study...

Organophosphate chronic toxicity has been evaluated in this study. Biological screening for organophosphate insecticide-exposed workers is mostly recommended for mixers, loaders, formulators and spraymen. We have studied 17 occupationally exposed persons to pesticides. Using Ellman's colorimetric method, their plasma cholinesterase activities have been measured. Results show that the appear...

The cohort (7676) of this historical prospective study consisted of a group of male chemical workers from seven plants who had been occupationally exposed (continuously or intermittently) to benzene for at least six months and a comparison group of male chemical workers from the same plants who had been employed for at least six months during the same period but were never occupationally expose...

The frequency of chromosomal aberrations was studied in the peripheral blood lymphocytes of 65 radiology technologists CRT) working at hospitals chronically exposed to x-rays. Although film dosimetry did not show the maximal annual permitted dose in any of the examined subjects, cytogenetic analysis detected fairly high levels of chromosomal aberrations in R T compared to unexposed controls...
