聚氯乙烯生產過程中對人體有危害的物質主要是氯乙烯與氯化汞。有關氯化汞對人體的危害已比較清楚。氯乙烯單體以往認為它對人體威脅不大。近幾年來,國內外報導,聚氯乙烯制造工,特別是聚合工序工人的肝腫大比例明顯高于對照組,部分有肝功能異常。國外資料報導,長期接觸氯乙烯的生產工人,可發生指端動脈痙攣,指端溶骨癥,硬皮病。
甲醇是無色透明,具有高度揮發性的液體,易與水,醚及大多數有機溶劑混溶.在醫藥,化工等產品的生產過程中作為原料,溶劑被廣泛使用.甲醇在人體內氧化為甲醛,甲酸,具有很強的毒性,尤其對視神經的毒性作用*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.
