Effects of Metal Oxide Nanoparticles on Nitrous Oxide Emissions in Agriculture Soil

چکیده

Metal oxide nanoparticles (NPs) have been widely used in industrial and agricultural production introduced into soils. The impact of these on soil nitrous (N2O) emission is unclear. We conducted a microcosm experiment to investigate the effects titanium (TiO2 NPs), copper (CuO aluminum (Al2O3 NPs) N2O emissions abundance functional genes related production/reduction. Compared without NPs addition, TiO2 applied produced no significant effect emissions. denitrification process exposed CuO was inhibited by reducing nitrite reductase (nirK) increasing (nosZ), while added stimulated cumulative 92.7%. After application Al2O3 soil, nitrification inhibiting ammonia-oxidizing bacteria (AOB amoA), reduced 48.6%. Large-scale soils may stimulate resulting potential environmental risks.

Nitrogen source and placement effects on soil nitrous oxide emissions from no-till corn.

A nitrogen (N) source comparison study was conducted to further evaluate the effects of inorganic N source and placement on growing-season and non-crop period soil nitrous oxide (NO). Commercially available controlled-release N fertilizers were evaluated for their potential to reduce NO emissions from a clay loam soil compared with conventionally used granular urea and urea-ammonium nitrate (UA...

Antimicrobial Effects of Metal Oxide Nanoparticles

and Introduction: In a world of emerging nanotechnology, one of the primary concerns is the potential environmental impact of nanoparticles (NPs). An efficient way to estimate nanotoxicity is to monitor the response of bacteria exposed to these particles [1]. This experiment explored the antimicrobial properties of nickel oxide, cobalt (II,III) oxide, zinc oxide, copper (II) oxide, iron (III) o...
