聚氯乙烯生产过程中对人体有危害的物质主要是氯乙烯与氯化汞。有关氯化汞对人体的危害已比较清楚。氯乙烯单体以往认为它对人体威胁不大。近几年来,国内外报导,聚氯乙烯制造工,特别是聚合工序工人的肝肿大比例明显高于对照组,部分有肝功能异常。国外资料报导,长期接触氯乙烯的生产工人,可发生指端动脉痉挛,指端溶骨症,硬皮病。
甲醇是无色透明,具有高度挥发性的液体,易与水,醚及大多数有机溶剂混溶.在医药,化工等产品的生产过程中作为原料,溶剂被广泛使用.甲醇在人体内氧化为甲醛,甲酸,具有很强的毒性,尤其对视神经的毒性作用*大。

The main harmful substances in the production process of PVC are vinyl chloride and mercury chloride. The harm of mercury chloride to the human body is relatively clear. In the past, vinyl chloride monomer was considered to be of little threat to the human body. In recent years, it has been reported at home and abroad that the proportion of hepatomegaly in PVC manufacturing workers, especially those in the polymerization process, is significantly higher than that in the control group, and some have abnormal liver function. Foreign data reported that production workers who have been exposed to vinyl chloride for a long time may suffer from fingertip arterial spasm, fingertip osteolysis, and scleroderma.
Methanol is a colorless, transparent, highly volatile liquid, and it is easily miscible with water, ether and most organic solvents. It is widely used as a raw material and solvent in the production process of pharmaceuticals, chemicals and other products. Methanol is oxidized in the human body to Formaldehyde and formic acid have strong toxicity, especially the most toxic effect on the optic nerve.
Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has developed a special packed column for HH-VOCMaNOL, which can simultaneously determine the content of vinyl chloride and methanol in ambient air with a single injection, with good separation and satisfactory results.
