Aircraft based four-channel thermal dissociation laser induced fluorescence instrument for simultaneous measurements of NO2, total peroxy nitrate, total alkyl nitrate, and HNO3 [PDF]

open access: yes, 2013
A four-channel thermal dissociation laser induced fluorescence (TD-LIF) instrument has been developed for simultaneous measurements of nitrogen dioxide (NO2), total peroxy nitrate (∑PNs), total alkyl nitrate (∑ANs) and nitric acid (HNO3). NO2 is measured

Competitive reaction modelling in aqueous systems. The case of contemporary reduction of dichromates and nitrates by nZVI [PDF]

open access: yes, 2017
In various Countries, Cr(VI) still represents one of the groundwater pollutant of major concern, mainly due to its high toxicity, furthermore enhanced by the synergic effect in presence of other contaminants.

Nutrient Balance from Agricultural Pollution Sources on Selected Tributaries to the Švihov Reservoir

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2022
Agriculture is the leading source of non-point sources of water pollution, especially in terms of the runoff process. Agricultural management promotes extensive water contamination, soil erosion and sedimentation in streams and reservoirs.

Characterization of nighttime formation of particulate organic nitrates based on high-resolution aerosol mass spectrometry in an urban atmosphere in China

open access: yesAtmospheric Chemistry and Physics, 2018
. Organic nitrates are important atmospheric species that significantly affect the cycling of NOx and ozone production. However, characterization of particulate organic nitrates and their sources in polluted atmosphere is a big challenge and has not been

Ozone and alkyl nitrate formation from the Deepwater Horizon oil spill atmospheric emissions [PDF]

open access: yes, 2012
Ozone (O3), alkyl nitrates (RONO2), and other photochemical products were formed in the atmosphere downwind from the Deepwater Horizon (DWH) oil spill by photochemical reactions of evaporating hydrocarbons with NOx (=NO+NO2) emissions from spill response

Abundances and variability of tropospheric volatile organic compounds at the South Pole and other Antarctic locations [PDF]

open access: yes, 2010
Multiyear (2000-2006) seasonal measurements of carbon monoxide, hydrocarbons, halogenated species, dimethyl sulfide, carbonyl sulfide and C1-C4 alkyl nitrates at the South Pole are presented for the first time.

Aminoethyl nitrate – the novel super nitrate? [PDF]

open access: yesBritish Journal of Pharmacology, 2009
Long‐term use of most organic nitrates is limited by development of tolerance, induction of oxidative stress and endothelial dysfunction. In this issue of the BJP, Schuhmacher et al. characterized a novel class of organic nitrates with amino moieties (aminoalkyl nitrates).

The production and persistence of ΣRONO2 in the Mexico City plume [PDF]

open access: yes, 2010
Alkyl and multifunctional nitrates (RONO2, ΣANs) have been observed to be a significant fraction of NOy in a number of different chemical regimes. Their formation is an important free radical chain termination step ending production of ozone and possibly

Hemodynamic effect of avanafil and glyceryl trinitrate coadministration

open access: yesDrugs in Context, 2013
A Phase I, double-blind, randomized, crossover study in healthy males (N=106) was conducted between March 21, 2004, and May 17, 2004, to determine the magnitude and duration of the hemodynamic interaction of avanafil (a phosphodiesterase type-5 inhibitor
