HIGH SISTER CHROMATID EXCHANGE AMONG A SAMPLE OF TRAFFIC POLICEMEN IN BANGKOK.THAILAND

摘要

There are several volatile substances from the traffic, including benzene, toluene, carbon monoxide, lead and formaldehyde. Most of these substances are considered carcinogens. Police are at occupational risk for toxic fume exposure This study compared sister chromatid exchange (SCE), a marker for genotoxicity, among a sample of Thai traffic policemen in Bangkok with healthy control subjects. Thirty police officers (all male) and 20 controls were included in this study The average (mean(+-)SD) SCE for policemen and controls were 4,40(+-)0 93/cell and 0.24(+-)0.12/cell, respectively A significantly higher SCE among the policemen was observed. Concern for and prevention of toxic substance exposure in traffic police officers should be made a national goal.
