德国化学工业雇主协会在一个初步的卫生调查中发现,长期从事橡胶工业工作的工人中死于癌症特别是肺癌的人数略高于一般居民。同时还调查了癌和化学物质如亚硝胺、多环烃、溶剂、粉尘和工艺系统之间可能的联系。 In a preliminary health survey, the German Federation of Chemical Industry Employers found that the number of workers who died in the long-term rubber industry was slightly higher than that of the general population. A possible link between cancer and chemicals such as nitrosamines, polycyclic hydrocarbons, solvents, dust, and process systems was also investigated.
