摘要: Abstract The daily evolution of seventeen sugar compounds (seven saccharides, seven alcohol-saccharides and three anhydrosaccharides) in atmospheric aerosol samples collected between 9 March 2016 14 2017 was studied Leon (Spain). main links the concentration various chemical species, pollen, fungal spores meteorological conditions were investigated. results showed that, spring, when high levels metabolic activity plants occur temperatures increase, glucose, sucrose, 2-methyl-erithritol, mannitol, arabitol inositol, are significantly correlated with airborne pollen concentrations. Between spring autumn, Alternaria air concentrations temperatures, sorbitol + adonitol Furthermore, during rainy days, is also mannitol. In lower cause an increase levoglucosan, mannosan galactosan, probably due to increased use domestic heating devices. These anhydrosugars arabinose, fructose K, NO3−, EC, OC, Cu, Zn, Se, Pb, V Ni, while correlates As, showing that these anhydrosaccharides can be emitted from different anthropogenic sources. Precipitation causes glucose sucrose concentrations, break particles produce hundreds fine size particles. Besides, precipitation release growth fungi.
