车内异味可能存在的物质都有哪些危害？
What are the hazards that may exist in the vehicle's peculiar smell?
甲醛
formaldehyde
甲醛是什么？简单地说，甲醛是一种无色，有强烈刺激型气味的气体，易溶于水、醇和醚。甲醛在常温下是气态，通常以水溶液形式出现，而我们熟悉的甲醛溶液，就是浓度为35～40%的福尔马林。它是一种原浆毒物，能与蛋白质结合。合成树脂、表面活性剂、塑料、橡胶、皮革等材料以及消毒、熏蒸和防腐过程中均要用到甲醛。
What is formaldehyde? Simply speaking, formaldehyde is a colorless, strongly irritation odorant, easily soluble in water, alcohol and ether. Formaldehyde is gaseous at normal temperature and usually occurs in aqueous solution. The familiar Formaldehyde Solution is formalin with a concentration of 35 to 40%. It is a protoplasmic poison that binds with protein. Synthetic resins, surfactants, plastics, rubber, leather and other materials, as well as disinfection, fumigation and anti-corrosion process, all use formaldehyde.
苯
benzene
苯在常温下为一种无色、有甜味的透明液体，并具有强烈的芳香气味。可燃，毒性较高，是一种致癌物质。可通过皮肤和呼吸道进入人体，体内比较难降解，因为其有毒，常用甲苯代替，苯是一种碳氢化合物也是简单的芳烃，苯易挥发，是工业上应用很广的原料。高浓度苯对中枢神经系统有麻醉作用，会引起急性中毒；长期接触苯对造血系统有损害。
Benzene is a colorless, sweet transparent liquid at room temperature and has strong aroma. Combustible, high toxicity, is a carcinogenic substance. Through the skin and respiratory tract into the human body, the body is more difficult to degrade, because of its toxic, commonly used toluene instead, benzene is a kind of hydrocarbon is simple aromatics, benzene volatilization, is a widely used raw material in industry. High concentration benzene has an anesthetic effect on the central nervous system, which can cause acute poisoning. Long-term exposure to benzene can damage the hematopoietic system.
甲苯
toluene
甲苯与苯相似，短时间内吸入较高浓度甲苯可出现眼及上呼吸道明显的刺激症状、眼结膜及咽部充血、头晕、恶心、步态蹒跚、意识模糊。
Toluene was similar to benzene. Inhalation of high toluene in a short time could show obvious irritation in the eye and upper respiratory tract, hyperemia of the conjunctiva and pharynx, dizziness, nausea, gait staggering, and blurred consciousness.
二甲苯
xylene
人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。二甲苯主要来自于合成纤维、塑料、燃料、橡胶等物质中和油漆、涂料添加剂以及胶粘剂、防水材料中。
Inhalation of high concentration toluene or xylene can cause symptoms of central nervous system anesthesia in a short time. Xylene mainly comes from synthetic fiber, plastic, fuel, rubber and other materials, and paint, paint additives and adhesives, waterproof materials.
