Teflon tubing used in the isolated, ventilated and perfused lung apparatus (IVPL) was found to yield artifactually high values for nitrosamine formation after it had been exposed to nitrite. In contrast to an earlier report, we found that submilligram levels of nitrite do not react to form significant quantities of nitrosamine in the IVPL apparatus over a period of 1 h if contamination from the tubing is prevented.
用于离体、通气和灌注肺装置（IVPL）的聚四氟乙烯管在暴露于亚硝酸盐后，被发现会产生人为偏高的亚硝胺形成值。与早期报告相反，我们发现，如果防止来自管道的污染，在1小时内，亚毫克水平的亚硝酸盐在IVPL装置中不会反应形成大量亚硝胺。
