Abstract
|
|
|
The average level of coke oven emissions in the work site was 0.04 ㎎/㎥, which was below the permissible exposure level(0.2 ㎎/㎥). The average level of 1-OH-pyrene in the urine of the workers was 0.745 μ㏖/㏖ creatinine which is far below the BEI(2.3 μ㏖/㏖ creatinine). Correlation between airborne COE in working environment and urinary 1-OH-pyrene concentration was statistically significant. These results explain that exposure level by biological monitoring is much higher than that by environmental monitoring.
The effect of hygienic measures for reducing internal exposure to polycyclic aromatic hydrocarbons was studied in 25 coke-oven workers. Their 1-OH-pyrene levels increased by 0.77 μ㏖/㏖ creatinine, while working with ordinary protective measures. The average levels of the same workers with extra hygienic measures increased by 0.34 μ㏖/㏖ creatinine. The average increase of the urinary 1-OH-pyrene concentration over the 5-day work week was 56.3%(0.43 μ㏖/㏖ creatinine) lower when extra hygienic measures were taken(p=0.0001).
