对某焦化厂焦化生产过程中产生的有害气体及环境尘毒逸散物危害作业人员的身体健康，作了初步调查及有关数据的监测。通过参照对比，发现焦化厂工人患呼吸道病症、鼻炎、咽喉炎、肺炎等的发病率明显高于对照组。该焦化厂所测到的毒物为苯、甲苯、二氧化硫、氮氧化物等，虽大部分测点未超标，但对人体仍然产生轻度中毒影响，应引起注意。 A coking plant coking production process generated harmful gases and environmental dust poisoning hazards to the health of workers, made a preliminary survey and the monitoring of the data. By referring to the comparison, found that workers in coking plant suffering from respiratory diseases, rhinitis, pharyngitis, pneumonia, the incidence was significantly higher than the control group. The coking plant measured the poison benzene, toluene, sulfur dioxide, nitrogen oxides, etc., although most of the measuring point is not exceeded, but the human body is still mild poisoning, should cause for concern.
