Volatile aromatic hydrocarbons mainly from synthetic fibers, plastics, rubber, fuel and other, hidden in the of all kinds of paint additives and various adhesives, waterproof materials, can also come from the combustion of fuel and tobacco. Due to aromatic hydrocarbons make sometimes difficult to alert its toxicity, if in the dissemination of the smell of the sealed room, within a short time inhalation of high concentrations of toluene or xylene, central nervous narcotic symptoms and mild dizziness, nausea, chest tightness, fatigue, serious will coma and even due to respiratory and circulatory failure and death. Frequent contact with such compounds, the skin can change dry because of the degreasing, scaling, and some appear allergic eczema. Long-term inhalation can cause aplastic anemia, early gum and nasal mucosa have similar scurvy hemorrhagic disease, and neurasthenic symptom, manifested as dizziness, insomnia, fatigue, memory loss, thinking and judgment ability is reduced and other symptoms.
Tengzhou City Xiangying Analysis Technology Co., Ltd. developed soil and sediment of volatile aromatic hydrocarbons, determination of the XiangyingGC7990olus headspace gas phase chromatography and determination with satisfactory results.
挥发性芳香烃主要来自合成纤维、塑料、燃料、橡胶等，隐藏在各种涂料的添加剂以及各种胶黏剂、防水材料中，还可来自燃料和烟叶的燃烧。由于芳香烃类化合物使人一时不易警觉其毒性，如果在散发着气味的密封房间里，在短时间内吸入高浓度的甲苯或二甲苯，会出现中枢神经麻醉的症状，轻者头晕、恶心、胸闷、乏力，严重的会出现昏迷甚至因呼吸循环衰竭而死亡。经常接触此类化合物，皮肤可因脱脂而变干燥、脱屑，有的出现过敏性湿疹。长期吸入能导致再生障碍性贫血，初期时齿龈和鼻黏膜处有类似坏血病的出血症，并出现神经衰弱样症状，表现为头昏、失眠、乏力、记忆力减退、思维及判断能力降低等症状。
