【摘要】 采集并监测分析某焦化厂不同生产工段废气和附近敏感点环境空气中苯并(a)芘(BaP)的浓度。结果表明:该焦化厂厂区BaP浓度为1.49×10-5~2.35×10-4mg/m3,推焦处浓度最高;厂区BaP人体日暴露值为1.19×10-4~1.88×10-3mg/m3,其中推焦工日暴露值最高,为1.88×10-3mg/m3,应采取措施保障职工身体健康。更多还原

【Abstract】 BaP in air of different production sector in coking plant were measured. The result showed that the total BaP concentrations ranged from 1. 49 × 10-5~ 2. 35 × 10-4mg / m3,the concentration of the coke pushing was the highest; The calculation,workers’ daily exposure to BaP were 1. 19 × 10-4~ 1. 88 × 10-3mg / m3in coking plant,the highest workers’ daily exposure was 1. 88 × 10-3mg / m3at the coke pushing,so measures should be taken to protect the health of workers.更多还原
