Air pollution in cabins due to organic compounds diffusing from the interior materials was investigated in Japanese domestically produced private-use cars, and following conclusions were achieved.1. A total of 275 organic compounds, involving many aliphatic hydrocarbons and aromatic hydrocarbons, were identified in the interior air of the cabins. In addition, several characteristic compounds related to plastics, rubbers and resins, which are abundantly used in the cars, were found in the cabins.2. The aliphatic hydrocarbons and aromatic hydrocarbons of high airborne concentrations were demonstrated to be the main compounds contributing to air pollution in the cabins.3. Interior temperature and days lapsed from the delivery of the cars as new car were suggested to be the main factors affecting the interior concentrations of the organic compounds. Their concentrations were high especially immediately after delivery and in summer.4. Interior air pollution was more marked in the cabins of luxury cars, with leather seats or leather steering wheels or high-end catalog prices. Differences of specifications such as interior materials and automobile rank (grade) contributed more markedly than the manufacturer to interior air pollution in the cabins.5. Usage status such as everyday ventilation and parking environment, smoking and use of air fresheners also affected the long-term interior air quality of the cabins.6. The interior air in the cars immediately after delivery was suggested to be universally contaminated especially by very high concentrations of a large variety of chemicals diffusing from the interior materials originally present in the cabins.7. The sum of the concentrations for all of volatile organic compounds (TVOC concentration) in the interior air of an automotive cabin should be reduced to prevent adverse effects on the health of the drivers and passengers.

由于有机化合物从内部材料扩散而导致的机舱空气污染在日本产生的私人用途车中进行了研究，并得出了以下结论。1。在小木屋的内部空气中鉴定出了共有275种有机化合物，涉及许多脂肪烃和芳香烃。此外，在小木屋中发现了与塑料，橡胶和树脂有关的几种特征化合物，这些化合物在汽车中大量使用。2。证明高空浓度的脂族烃和芳族烃是造成空气污染的主要化合物。3。由于新车的传递，内部温度和天数被认为是影响有机化合物内部浓度的主要因素。他们的浓度很高，尤其是在分娩和夏季后立即浓度。4。内部空气污染在豪华汽车的小屋中更明显，皮革座椅或皮革转向轮或高端目录价格。与制造商相比，室内材料和汽车等级（等级）等规格的差异更明显地贡献了客舱内部空气污染。5。使用状态，例如日常通风和停车环境，吸烟和使用空气清新剂也影响了小木屋的长期内部空气质量。6。提议在交付后立即进行汽车的内部空气被普遍污染，尤其是通过非常高浓度的各种化学物质与最初存在于机舱中的内部材料扩散的高度。应降低汽车内部空气中所有挥发性有机化合物（TVOC浓度）的浓度之和，以防止对驾驶员和乘客的健康不利影响。
