Images from the BCN site
Primary Biogenic Organic Particles
Despite not being an important group in abundance, the microscopy analysis of PM2.5 samples from BCN site revealed a very rich diversity of this particle type. Several families of spores, vegetative and insect detritus and bacteria have been identified with sizes from 300 nm up to 4 µm. Some of them are frequently mixed with other anthropogenic aerosols.
