The maximum permissible concentration (MPC) of chloroprene was set at 2 mg/m3 in the USSR in the 1940's. The existing MPC is 4 mg/m3. The threshold of systemic effects as a result of chronic chloroprene exposure is l.69 mg/m3. However, the threshold for embryotoxic and mutagenic effects is 0.15 mg/m3. In consideration of this information, setting a new MPC for chloroprene at 0.05 mg/m3 is recommended.
20世纪40年代,苏联将氯丁二烯的最大允许浓度(MPC)设定为2毫克/立方米。现行的MPC为4毫克/立方米。长期接触氯丁二烯产生全身影响的阈值为1.69毫克/立方米。然而,胚胎毒性和致突变作用的阈值为0.15毫克/立方米。考虑到这些信息,建议将氯丁二烯的新MPC设定为0.05毫克/立方米。
