ABSTRACT
Objective@#To evaluate the inner or extra-exposure of workers in carbon and coal tar process industries.@*Methods@#In May 2015, 271 exposure and 75 non-exposure workers in two of carbon and coal tar process industries in Shandong province were selected. Coal tar pitch (CTP) was detected according to the methods of GB17054-1997. The 1-OH-Nap、2-OH-Nap、1-OH-Pyr in urine were detected by high performance liquid Chromatography (HPLC) .@*Results@#The concentration of 1-OH-Nap、2-OH-Nap、1-OH-Pyr in urine of exposure group were significant higher than that of control group (P<0.05) , respectively. The urine concentration of 1-OH-Nap、2-OH-Nap、1-OH-Py in contact group tar and asphalt were 12.20, 12.55, 7.08 and 10.62, 8.73, 3.07 μg/gCr, and the concentration of them were 7.25, 8.54, 3.00 μg/gCr in container handle workers. Significant positive correlations were found between high or median CTP exposure and the urine concentration of 1-OH-Nap、2-OH-Nap、1-OH-Pyr in exposure groups (P<0.05) .@*Conclusions@#The inner or extra exposure level is relative and different for different type of work in these carbon and coal tar process industries.
