To verify these directly- calculated mass exchange rates, we apply them to model the leaching of the inert tracer and the reactive nitrate in an aggregated soil column.
At relatively low temperatures, both ionic NH4+ and coordinated NH3 contributed to the SCR reaction, and both bridging nitrate and monodentate nitrate were confirmed to be the reactive nitrate species.
This is mainly owing to the formation of larger proportion of monodentate nitrate, which is the real reactive nitrate species in the NOx reduction process, among total nitrate species on the surface of FeTiOx catalysts with higher crystallization degree.
This finding also shows that the observed cytotoxicity was not due to secondary reactive nitrate species within the N-SYN solution, such as peroxynitrite, since these are able to cross cell membranes [37].
This pattern of MMR expression was reproduced by synovial fibroblasts exposed to reactive nitrate species and to a smaller extent by fibroblasts exposed to ROS, indicating a role for oxidative stress in the development of microsatellite instability in RA.
Soluble reactive phosphorous, nitrate nitrogen (NO3 N), and ammonia (NH4 N) were determined from the filtrate (Whatman GFC) using the ammonium molybdate method (Wetzel & Likens, 2000), sodium salicylate method (Müller & Wiedemann, 1955) and the indophenol blue method (Krom, 1982), respectively.
Here we review the available thermodynamic and kinetic data for H2S and HS as well as O2, reactive oxygen species, nitrate, nitrite, and NOx species.
Groundwater contaminant transport models are being used increasingly to simulate the fate and transport of reactive solutes, particularly nitrate, within aquifer systems.
Though the book is primarily intended for graduate students and applied scientists who deal with hydrological modeling, it also offers a valuable source of information for professional geoscientists wishing to expand their knowledge of the numerical modeling of hydrological processes including nitrate reactive transport modeling.
The gulf has an irregular shoreline extending with its longest axis from SW to NE (Fig. 1), showing a pronounced spatial variation in the concentration of macronutrients, such as soluble reactive phosphorus (SRP), nitrate (NO3 N), and soluble reactive silica (SRSi) (Gikuma-Njuru & Hecky, 2005).
Water samples were taken every other week at 12 locations along these treatment basins over the period March 2, 2016 February 20172017 and analyzed for nutrients [total phosphorus, soluble reactive phosphorus (SRP), nitrates, total Kjeldahl nitrogen, and total nitrogen] and turbidity.
