Influence of local air pollution on the deposition of peroxyacetyl nitrate to a nutrient-poor natural grassland ecosystem
Dry deposition of peroxyacetyl nitrate (PAN) is known to have a phytotoxic impact on plants under photochemical smog conditions, but it may also lead to higher productivity and threaten species richness of vulnerable ecosystems in remote regions. However, underlying mechanisms or controlling factors for PAN deposition are not well understood and studies on dry deposition of PAN are limited. In ...

متن کاملPeroxyacetyl nitrate (PAN) and peroxypropionyl nitrate (PPN)
Atmospheric Chemistry and Physics Discussions This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract Peroxyacetyl nitrate (PAN) and peroxypropionyl nitrate (PPN) were measured sequentially in situ by an online gas-phase chromatograph with electron capture detector at urba...
متن کاملReaction of peroxyacetyl nitrate with glutathione.
Peroxyacetyl nitrate reacts with the sulfhydryl groups of reduced glutathione. Thioester formation accounts for as much as 50% of the reacted sulfhydryl groups. As much as 60% of the reacted sulfhydryl groups can be accounted for as oxidized glutathione. The stoichiometry of the reaction is approximately 3 moles of sulfhydryl reacting per mole of peroxyacetyl nitrate, and this stoichiometry is ...
متن کاملInteractive comment on “Air–snow exchange of nitrate: a modelling approach to investigate physicochemical processes in surface snow at Dome
In this paper, Bock et al. develop numerical models to analyze physical mechanisms behind the incorporation of nitrate from ambient air into surface snow at Dome C, Antarctica. Four different types of the models are developed, each of which is applied to simulate the evolution of nitrate concentrations in a single grain of the surface snow over one annual cycle. Each model is constrained by mea...
