Determination of free amino acids, saccharides, and selected microbes in biogenic atmospheric aerosols – seasonal variations, particle size distribution, chemical and microbial relations
Jose Ruiz-Jimenez,Magdalena Okuljar,Outi-Maaria Sietiö,Giorgia Demaria,Thanaporn Liangsupree,Elisa Zagatti,Juho Aalto,Kari Hartonen,Jussi Heinonsalo,Jaana Bäck,Tuukka Petäjä,Marja-Liisa Riekkola +11 more
TL;DR: In this paper, the authors explored the complex interrelationships between airborne and particulate chemical tracers (amino acids, saccharides), gene copy numbers and size distributions of bacteria, Pseudomonas, and fungi in biogenic aerosols by DNA extraction and amplification.

New particle formation in the western Yangtze River Delta: first data from SORPES-station
Erik Herrmann,Erik Herrmann,Aijun Ding,Tuukka Petäjä,Xiu-Qun Yang,Jianqi Sun,Ximeng Qi,Hanna E. Manninen,Jani Hakala,Tuomo Nieminen,Pasi Aalto,V.-M. Kerminen,Markku Kulmala,Congbin Fu +13 more
TL;DR: In this paper, the authors studied new particle formation in the western part of the Yangtze River Delta (YRD) at the SORPES station of Nanjing University using an air ion spectrometer; a DMPS provided particle size distributions between 6 and 800 nm.
