为了研究被认为是在从事氯苯甲酰制造作业者中发生的肺癌及鼻恶性淋巴肿的起因物质——氯苯甲酰(BC)和二氯甲苯(BTC)的致癌性,作者等把127只小白鼠分成①BTC50℃暴露组(32只):把BTC在50℃气化,吸入暴露。②BTC室温暴露组(37只):把BTC于室温气化,吸入暴露。③BC50℃暴露组(28只):把BC于50℃气化,吸入暴露。④对照组(30只)。进行了实验研究。然后综合其研究结果得到了如下的结论: 1、就BTC在室温及50℃气化吸入暴露来说,诱发肺瘤(腺肿、肺癌)的发生率高。
In order to study the carcinogenicity of chlorobenzoyl (BC) and dichlorobenzene (BTC), which are considered to be the causative agents of lung cancer and nasal lymph nodes that occur in chlorobenzoyl manufacturing workers, Only white mice were divided into ①TCTC50 ℃ exposure group (32): BTC gasified at 50 ℃, inhalation exposure. ② BTC room temperature exposure group (37): BTC gasification at room temperature, inhalation exposure. ③ BC50 exposure group (28): BC at 50 ℃ gasification, inhalation exposure. ④ control group (30). An experimental study was carried out. Based on the results of this study, the following conclusions are drawn: 1. The incidence of tumor-inducing tumors such as adenoma and lung cancer is high in BTC inhalation exposure at room temperature and 50 ° C.
