Fibers are found in all environments. However, the impact of their presence on ecosystems and human health is not yet well understood, especially case atmosphere. In this work, we presented evidence that fibers traveling through atmosphere act as vectors to spread microorganisms. Here, investigated viable microorganisms collected within beyond planetary boundary layer during flights C-212 aircraft over Central Spain. total, seven fibers, six which transported microorganisms, were isolated two flights. The viability was determined by confocal microscopy means fluorescent probes SYBR-Green detect CTC redox dye assess cellular respiration activity. spectroscopically analyzed micro-FTIR identified wool-silk cellulose-cotton. Taken together, results demonstrated host when lower free troposphere.
