Abstract
One hundred twenty-two workers (sixteen from a coke production plant and 106 from a graphite electrode manufacturing plant) agreed to participate in this study evaluating the relationship between exposure to polycyclic aromatic hydrocarbons (PAHs) and urinary excretion of 1-hydroxypyrene (1-HOP), the main metabolite of pyrene. The results show that the concentration of pyrene in air is highly correlated with total PAHs (r equals 0.83, P < 0.0001). The correlation coefficient between pyrene in air and 1-HOP is (r equals 0.69, P < 0.0001) and between 1-HOP and total PAHs is (r equals 0.77, P < 0.0001). The biological half life of the 1-HOP was determined (18 hrs) and the noninterference of smoking habits in relation to 1-HOP urinary excretion was established, concluding that 1-HOP is a suitable bioindicator of the occupational exposure to PAHs.
