聚四氟乙烯(下称四氟)本身对人体一般是无害的,但在制造或加工过程中,其裂解和热解产物可引起急性中毒和慢性损害。人们对急性中毒逐步有所认识,慢性损害问题尚无统一的看法。1974年我们对××塑料研究所四氟加工车间的38人作了检查,其中男性16人,女性22人。年龄:16～56岁。工龄:8个月～8年(大部分为2—5年),工种包括模压工、 PTFE (hereinafter referred to as PTFE) itself is generally harmless to the human body, but during manufacture or processing, its pyrolysis and pyrolysis products can cause acute poisoning and chronic damage. People gradually recognize that acute poisoning, there is no unanimous view on the issue of chronic damage. In 1974, we examined 38 people at the tetrafluorofluorocarbon processing plant at ×× Plastic Research Institute, of which 16 were males and 22 were females. Age: 16 ~ 56 years old. Length of service: 8 months to 8 years (mostly 2-5 years), types of workers include molding workers,
