||Exposure to bitumen fumes and genotoxic effects on Turkish asphalt workers
||Apr.-May 2009, Vol.47, No.4, p.321-326. Illus. 59 ref.
||The aim of this study was to investigate exposure to asphalt fumes among Turkish asphalt workers and to determine whether any effects could be detected with genotoxic tests. The study included 26 asphalt workers and 24 control subjects. Sister chromatid exchange (SCE) and micronucleus (MN) were determined in peripheral lymphocytes. Urinary 1-hydroxypyrene (1-OHP) excretion was used as a biomarker of occupational exposure to PAHs. The asphalt workers had a significant increase in SCEs and MN. A positive correlation existed between the duration of exposure and rates of SCE or MN frequencies. The concentration of 1-OHP in urine was higher for the asphalt workers than for the controls. However, there was no statistically significant correlation between the urinary 1-OHP concentration and SCEs or MN frequencies.
