Potential Human and Plant Pathogenic Species in Airborne PM10 Samples and Relationships with Chemical Components and Meteorological Parameters

A preliminary local database of potential (opportunistic) airborne human and plant pathogenic non-pathogenic species detected in PM10 samples collected winter spring is provided, addition to their seasonal dependence relationships with meteorological parameters chemical species. The samples, at a Central Mediterranean coastal site, were analyzed by the 16S rRNA gene metabarcoding approach, Spearman correlation coefficients redundancy discriminant analysis tri-plots used investigate main relationships. screening 1187 allowed for detection 76 27 pathogens, respectively. bacterial structure both varied from and, consequently, inter-species among spring. Few even fewer pathogens significantly correlated parameters, according coefficients. Conversely, several strongly positively temperature wind speed direction number strong between presumptive (human plant) non-pathogens, slightly increased sample composition also Some chemicals mainly associated marine aerosol and/or soil dust, likely because terrestrial aquatic environments habitats carrier role on variability was investigated.
