挥发性N-亚硝胺类污染物与轮胎、橡胶产品以及鞣皮工艺有关。因此,当这些产品在有限空间内使用时,空气中可能存在亚硝胺类化合物。为了验证这种假设,作者测定了新汽车车内的挥发性N-亚硝胺类化合物。作者采用热吸附(Thermo sorb/N)采样系统,它既能避免空气中原有物质生成亚硝胺,又能100%地吸附空气中的亚硝胺类化合物。共测定了38辆汽车,采样流量:2～3升/分,采 Volatile N-nitrosamine pollutants and tires, rubber products and tanning process. Therefore, when these products are used in confined spaces, nitrosamines may be present in the air. To test this hypothesis, the authors determined the volatile N-nitrosamines in the new car. The authors use a Thermo sorb / N sampling system that avoids the formation of nitrosamines in the air and nitrosamines in the air at 100%. A total of 38 vehicles were measured, the sampling flow: 2 ~ 3 liters / min, mining
