甲醇是工业生产中经常使用的一种挥发性溶剂,环境中超过一定浓度就会引起中毒。为了了解人体作业时接受甲醇的情况,作者以印刷厂接触甲醇蒸气的20人为对象,通过在工作前后检查他们血、尿中的甲酸及呼气中的甲醇浓度,选择甲醇的接触指标。作者还分别选择了36人及15人做为不接触甲醇的对照 Methanol is a volatile solvent frequently used in industrial production. It can cause poisoning if it exceeds a certain concentration in the environment. In order to understand the case of human exposure to methanol, the author selected 20 contact persons for the methanol exposure of the printing plant, and examined the methanol concentrations in formic acid and exhaled urine before and after the work, and selected the contact index of methanol. The authors also selected 36 and 15 respectively as controls for non-exposure to methanol
