为进一节探讨焦炉工肺癌高发的病因,将用仿CYQ-06流量采样器,49型超细玻璃纤维滤膜系集焦炉烟雾尘,并在索氏提取器内用甲醇液提取,放于KD浓缩器内浓缩至干。测定苯并(a)芘含量及其它多环芳烃量。本实验分提取物组、苯并(a)芘组和对照组,
In order to investigate the cause of the high incidence of lung cancer in coke oven workers, a CYQ-06 flow sampler and type 49 ultrafine glass fiber filter will be used to collect coke oven dust and extract it in a Soxhlet extractor with methanol solution. Place in a KD concentrator and concentrate to dryness. Determination of benzo(a)pyrene content and other polycyclic aromatic hydrocarbons. The experiment was divided into extract group, benzo(a)pyrene group and control group.
