塑料是高分子化合物之一,是目前世界上产量最大、使用最广的高分子合成材料。国内塑料制品大多是以聚氯乙烯树脂为原料,在加工中常会有裂解物产生,可引起呼吸道为主的职业病危害。为了解塑料制品生产过程中对生产工人鼻、咽喉的职业性影响,我们于2008年4—10月,调查了某塑料制 Plastic is one of the polymer compounds, is currently the world's largest and most widely used polymer materials. Most of the domestic plastic products are made of polyvinyl chloride resin as raw materials, often in the processing of lysate, can cause respiratory-based occupational hazards. In order to understand the occupational impact on the nose and throat of workers in the production of plastic products, we investigated the plasticity
