According to RT-PCR and 3D-RT-PCR analysis, dual RdRP and N1 gene positivity were detected in 20 (9.8 %) of the samples. The highest percentage of virus detection on PM [particulate matter] samples was from hospital gardens in Tekirdag, Zonguldak, and Istanbul, especially in PM2.5 mode. Samples collected from two urban sites were also positive. Findings of this study have suggested that SARS CoV2 may be transported by ambient particles especially at sites close to the infection hot-spots.
