Better understanding of process controls over nitrous oxide (N2O) production in urine-impacted 'hot spots' and fertilizer bands is needed to improve mitigation strategies and emission models. Following amendment with bovine (Bos taurus) urine (Bu) or urea (Ur), we measured inorganic N, pH, N2O, and genes associated with nitrification in two soils ('L' and 'W') having similar texture, pH, C, and...

The exploration of spatial variation and predictors of the effects of nitrogen dioxide (NO2) on fatal health outcomes is still sparse. In a multilevel case-crossover study in Beijing, China, we used mixed Cox proportional hazard model to examine the citywide effects and conditional logistic regression to evaluate the district-specific effects of NO2 on cardiovascular mortality. District-specifi...

CONTEXT There is a relative lack of studies about exhaled nitrite (NO2-) concentrations in cirrhotic and transplanted patients. OBJECTIVE Verify possible differences and correlations between the levels of NO2-, measured in plasma and exhaled breath condensate collected from patients with cirrhosis and liver transplant. METHOD Sixty adult male patients, aged between 27 and 67 years, were sub...

Synthesis of nitrite (NO2-) and nitrate (NO3-) was studied in the macrophage cell lines RAW 264.7, WEHI-3, PU5-1.8, J774A.1, and P388D1 and compared to the synthesis by thioglycolate-elicited peritoneal macrophages from C3H/He and C3H/HeJ mice. Treatment with Escherichia coli lipopolysaccharide (LPS) induced NO2-/NO3- synthesis by all the cell lines except P388D1, which remained unresponsive at...

The current perspective holds that the generation of secondary signaling mediators from nitrite (NO2(-)) requires acidification to nitrous acid (HNO2) or metal catalysis. Herein, the use of stable isotope-labeled NO2(-) and LC-MS/MS analysis of products reveals that NO2(-) also participates in fatty acid nitration and thiol S-nitrosation at neutral pH. These reactions occur in the absence of me...

The heterogeneous oxidation of SO2 by NO2 on mineral dust was studied using Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) and a Knudsen cell. This made it possible to characterise, kinetically, both the formation of sulfate and nitrate as surface products and the gas phase loss of the reactive species. The gas phase loss rate was determined to be first order in both SO2 a...
