使用3种分析技术记录了6所科罗拉多公立学校设施的空气中石棉水平，这些设施使用了喷洒的石棉材料。相差显微镜显示的水平高达千分之一纤维/cm 3（f/cc），扫描电子显微镜（SEM）高达百分之一f/cc和透射电子显微镜耦合到选定的区域电子衍射和能量色散X射线分析（TEM-SAED-EDXA）高达十分之一的石棉f/cc。相差显微镜是一个不充分的分析技术，记录在学校的空气中石棉纤维的水平;只有大的纤维，没有嵌入过滤器进行了计数，石棉纤维和非石棉没有区别。
Levels of airborne asbestos for 6 Colorado public school facilities with sprayed-on asbestos materials were documented using 3 analytical techniques. Phase contrast microscopy showed levels up to the thousandths of a fiber/cm3 (f/cc), scanning electron microscopy (SEM) up to the hundredths of a f/cc and transmission electron microscopy coupled to selected area electron diffraction and energy dispersive X-ray analysis (TEM-SAED-EDXA) up to the tenths of an asbestos f/cc. Phase contrast microscopy was an inadequate analytical technique for documenting the levels of airborne asbestos fibers in the schools; only large fibers which were not embedded in the filter were counted, and asbestos fibers were not distinguished from nonasbestos.
