The present paper reviews existing knowledge with regard to Organic Aerosol (OA) of
importance for global climate modelling and defines critical gaps needed to reduce the involved …

The Mediterranean Intensive Oxidant Study, performed in the summer of 2001, uncovered
air pollution layers from the surface to an altitude of 15 kilometers. In the boundary layer, air …

Samples of organic aerosol were collected in Santiago de Chile. An activated-charcoal
diffusion denuder was used to strip out organic vapors prior to particle collection. Both …

Glutamate dehydrogenase (GDH) may be a stress-responsive enzyme, as GDH exhibits
considerable thermal stability, and de novo synthesis of the α-GDH subunit is induced by …

Aerosol formation in the atmosphere is an important process to understand, in that such
particles may act as the cloud condensation nuclei responsible for the ‘cloud–climate’effect 1, …

… Methylated PAHs related to petrogenic sources were mostly present in the gas phase (eg
methyl-phenanthrenes (Me-Ph) and dimethyl-phenanthrenes (DMP); Table 4). On the contrary, …

… 1A, btl), ranged from C25 to C40, had a unimodal distribution and maximized at C31 (eg …
mode and at C29 in the second mode (eg samples ra303, ra85). The homologues distributions (…

… Each selected site was repeatedly geocoded using a GPS (eg at each start of a … plotted
and checked on GIS maps with high resolution (eg road network, building ground map) and, if …

… This is firmly confirmed by the occurrence of specific biomarkers (eg, hopanes, see below).
UCM levels in the Cretan Sea sediments were, however, much lower than those found in …

Background The distribution of microorganisms, and especially pathogens, over airborne
particles of different sizes has been ignored to a large extent, but it could have significant …
