目前国内普遍采用热解吸气相色谱方法检测室内空气中苯的含量。笔者主要研究了热解吸气相色谱法在苯测定过程中存在的影响因素,并得出了最佳的热解吸条件。调查发现,室内苯污染主要来自建筑装饰中大量的化工原材料,如涂料、填料及各种有机溶剂,如家俱,厨柜,天花板,木地板等。慢性苯中毒主要是苯对皮肤、眼睛 At present, pyrolysis gas chromatography is widely used to detect benzene in indoor air. The author mainly studied the influencing factors in the determination of benzene by pyrolysis gas chromatography, and obtained the best thermal desorption conditions. The survey found that indoor benzene pollution mainly from building decoration in a large number of chemical raw materials, such as coatings, fillers and a variety of organic solvents, such as furniture, kitchen cabinets, ceilings, wood flooring. Chronic benzene poisoning is benzene on the skin, eyes
