Hydrologists find Mississippi River network's buffering system for nitrates is overwhelmed
Hydrologists find Mississippi River network's buffering system nitrates is overwhelmed
2014/6/12
AUSTIN, Texas — A new method of measuring the interaction of surface water and groundwater along the length of the Mississippi River network adds fresh evidence that the network’s natural ability to c...
Isoprene nitrates: preparation, separation, identification, yields, and atmospheric chemistry
Isoprene nitrates atmospheric chemistry
2010/8/16
Isoprene is an important atmospheric volatile organic compound involved in ozone production and NOx (NO+NO2) sequestration and transport. Isoprene reaction with OH in the presence of NO can form eithe...
An efficient synthesis of Schiff bases containing benzimidazole moiety catalyzed by transition metal nitrates
Aldehyde 2-aminobenzimidazole catalyst Schiff bases
2010/10/18
A simple and efficient method has been developed for the synthesis of some novel Schiff bases via the reaction of aromatic aldehydes with 2-aminobenzimidazole by using catalytic amount of M(NO3)2.xH2O...
Temporal variability, sources, and sinks of C1-C5 alkyl nitrates in coastal New England
Temporal variability C1-C5 alkyl nitrates coastal New England
2010/2/21
Seven C1-C5 alkyl nitrates were measured both on the mainland and off the coast of New Hampshire using gas chromatographic techniques. Five separate data sets are presented to characterize the seasona...
GROUNDWATER AND NITRATES IN GREECE - AN OVERVIEW
GROUNDWATER NITRATES GREECE - AN OVERVIEW
2009/10/19
A project has been carried out to evaluate nitrates in groundwater in Greece and to subsequently establish a continuous monitoring and data analysis program, according to directive 91/676 of the Europ...
Closing the peroxy acetyl nitrate budget: observations of acyl peroxy nitrates (PAN, PPN, and MPAN) during BEARPEX 2007
peroxy acetyl nitrate budget acyl peroxy nitrates BEARPEX 2007
2009/10/13
Acyl peroxy nitrates (APNs, also known as PANs) are formed from the oxidation of aldehydes and other oxygenated VOC (oVOC) in the presence of NO2. There are both anthropogenic and biogenic oVOC precur...
Isoprene photooxidation: new insights into the production of acids and organic nitrates
Isoprene photooxidation new insights acids and organic nitrates
2009/3/13
We describe a nearly explicit chemical mechanism for isoprene photooxidation guided by chamber studies that include time-resolved observation of an extensive suite of volatile compounds. We provide ne...
Airborne observations of total RONO2: new constraints on the yield and lifetime of isoprene nitrates
Airborne observations yield lifetime isoprene nitrates
2009/3/13
Formation of isoprene nitrates (INs) is an important free radical chain termination step ending production of ozone and possibly affecting formation of secondary organic aerosol. Isoprene nitrates als...
Eddy covariance fluxes of acyl peroxy nitrates (PAN, PPN and MPAN) above a Ponderosa pine forest
Eddy covariance fluxes acyl peroxy nitrates PAN PPN MPAN Ponderosa pine forest
2009/3/12
During the Biosphere Effects on AeRosols and Photochemistry EXperiment 2007 (BEARPEX-2007), we observed eddy covariance (EC) fluxes of speciated acyl peroxy nitrates (APNs), including peroxyacetyl nit...
Fluxes of nitrates between snow surfaces and the atmosphere in the European high Arctic
Fluxes of nitrates snow surfaces atmosphere European high Arctic
2009/3/10
Measurements of atmospheric and snow mixing ratios of nitrates and nitrites and their fluxes above the snow surface were made during two intensive campaigns during spring time 2001 at Ny-Ålesund...
Comparison of measurements of peroxyacyl nitrates and primary carbonaceous aerosol concentrations in Mexico City determined in 1997 and 2003
peroxyacyl nitrates carbonaceous aerosol concentrations Mexico City
2008/12/9
The concentrations of peroxyacetyl nitrate (PAN) in ambient air can be a good indicator of air quality and the effectiveness of control strategies for reducing ozone levels in urban areas. As PAN is f...
Observations of total peroxy nitrates and aldehydes: measurement interpretation and inference of OH radical concentrations
total peroxy nitrates aldehydes OH radical concentrations
2008/12/8
We describe measurements of total peroxy nitrates (ΣPNs), NO2, O3 and several aldehydes at Granite Bay, California, during the Chemistry and Transport of the Sacramento Urban Plume-2001 (CATSUP 2001) ...
