[Determination of acrylonitrile in injection molding process: data analysis and recommendations].

Objective: To investigate whether the identification of acrylonitrile, an occupational hazard factor for the industry of injection molding and plastic products, reported in literature is reasonable, and to put forward some recommendations. Methods: Professional articles published from 1990 to 2016 were searched, and an analysis was performed for the data on the determination of acrylonitrile in the industry of injection molding and plastic products from 2003 to 2016 in Longhua Center for Disease Control and Prevention of Shenzhen. Results: According to the literature, the detection rate of acrylonitrile was 10.7%, and the detection results did not exceed the limit. Conclusion: At present, acrylonitrile may not be used as a routine test item for the industry of injection molding and plastic products, in order to save manpower and material resources.
