叶蝉散(2-异丙基苯基-N-甲基氨基甲酸酯,简称MIPC,下同),是广泛使用的一种高效低毒有机氮杀虫剂,使用的剂型有粉剂和乳剂,生产场所空气中最高容许浓度和标准监测检验方法,我国尚未规定。曾有文献报道,采用4—氨基安替比林比色法测定空气中叶蝉散,该法操作较繁(《工业卫生与职业病》1988年14卷102页)。为了适应劳动卫生经常性监 Leafhoppers (2-isopropylphenyl-N-methyl carbamate, referred to as MIPC, the same below), is widely used as a highly efficient and low toxicity organic nitrogen pesticides, the use of powder and emulsion dosage forms , The maximum allowable concentration of air in the production site and standard monitoring and inspection methods, China has not yet provided. It has been reported in the literature, the use of 4-amino-antipyrine colorimetric determination of leaf-cummin in the air, the method is more complicated (“Industrial Hygiene and Occupational Diseases” 1988 Volume 14, page 102). In order to adapt to labor and health regular supervision
