作者于1980年对某电石厂聚氯乙烯车间进行了卫生学调查,并选某加工厂工人做为对照。一、氯乙烯浓度测定氯乙烯的平均浓度:氯乙烯工段平均为102.4mg/m~3,聚合工段46.8mg/m~3,包装工段44.5mg/m~3。压缩机室平均浓度为405.3mg/m~3,最高可达1079.6mg/m~3。其主要工种每天8小时的接触的平均浓度见下表。
In 1980, the author conducted a hygiene survey on a polyvinyl chloride plant in a calcium carbide plant and selected workers from a certain factory as a control. First, the determination of vinyl chloride concentration The average concentration of vinyl chloride: vinyl chloride average of 102.4mg / m ~ 3, polymerization section 46.8mg / m ~ 3, packaging section 44.5mg / m ~ 3. Compressor room average concentration of 405.3mg / m ~ 3, up to 1079.6mg / m ~ 3. The average concentration of 8 hours of daily exposure to its main types of work is given in the table below.
