R. Chandrasekaran et al., INCREASED SISTER-CHROMATID EXCHANGE (SCE) FREQUENCIES IN LYMPHOCYTES FROM TRAFFIC POLICEMEN EXPOSED TO AUTOMOBILE EXHAUST POLLUTION, Human & experimental toxicology, 15(4), 1996, pp. 301-304
Sister chromatid exchange (SCE) frequencies were determined in periphe
ral lymphocytes from traffic policemen drawn from various busy traffic
points of Madras metro in India. These policemen were under constant
exposure to automobile exhaust pollution during their 8 h work schedul
e. Analysis of SCE frequencies revealed a significantly greater number
of SCE/cell in these policemen as against the matched control populat
ion. Sixty percent of these subjects who remained in the service after
5 years showed insignificant but higher values of SCE than in the ini
tial analysis.
