1.1本规程涵盖了城市固体废物处理设施（以下简称设施）中空气微生物的采样。调查人员应参考规程D1357，了解进行空气采样计划的一般原则。 1.2本规程仅适用于采样空气中的细菌和真菌，而不适用于病毒。由于对空气传播的病毒进行采样要比对细菌和真菌进行采样困难得多，目前还没有可靠的病毒采样方法。

1.1 This practice covers sampling of airborne microorganisms at municipal solid-waste processing facilities, hereafter referred to as facilities. Investigators should consult Practice D1357 for the general principles of conducting an air-sampling program. 1.2 This practice applies only to sampling airborne bacteria and fungi, not viruses. Since sampling airborne viruses is significantly more difficult than sampling bacteria and fungi, reliable methods of sampling viruses are not yet available.
