最近几年作者测定了一些应用苯的实验室,现简短报告一些调查结果。生化实验室:自1970年夏起,实验室每周二次分析黄体酮和β-雌二醇,以含苯85%的溶剂淬取三个小层析柱中的类固醇,并倒入试管和烧瓶中。房间很小,只有一般的通风设备。化学师血液中白细胞降低至2,900以下,其中粒细胞仅1,300。1971年7月停止分析工作后,其白细胞计数又回升到正常水平。在同一房间中一名年轻的女实验员做实验辅助工作(从1971年1月19日—5月19日),其血小板明显降低,在停止工作时又恢复正常。骨髓象正常。以气相色谱测定工作地点的苯浓度为17～22ppm,尿酚未测定。
In recent years, the authors have measured some laboratories using benzene and now briefly report some findings. Biochemical Laboratory: Since the summer of 1970, the laboratory analyzed progesterone and beta-estradiol twice a week, sterilized the three small columns with 85% benzene and poured them into test tubes and flasks in. The room is small with only general ventilation. Chemists in the blood white blood cells decreased to 2,900 or less, of which only 1,300 granulocytes .1971 July to stop the analysis, the white blood cell count was back to normal levels. A young female lab assistant did experimental work in the same room (from January 19, 1971 to May 19, 1971). The platelets were significantly reduced and returned to normal when they stopped working. Bone marrow as normal. Determination of benzene by gas chromatography at the workplace of 17 ~ 22ppm, uricol not measured.
