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.

BCN01-16 Spore.jpg Particle 1
Fungi spore
Size = 3.3 µm
Composition: Major components: C, O; Minor components: S, Cl, Ca

Notes:
Hiliferous appendix on the lower right, smooth ornament

FEI BCN012 1.jpg Particle 2
Non classified
Size = 410 nm
Composition: Major components: C, O; Minor components: S, Cl

Notes:
Morphology with circular aperture and ornament that reminds a fungi spore

FEI BCN04 21.jpg Particle 3
Vegetative detritus
Size = 800 nm
Composition: Major components: C, O; Minor components: Al, Si (not always)

Notes:
The morphology reminds a vegetative tissue in which some volatile material was initizlly entrapped (see the open cut)
