New Emission Factors for Calculation of Ammonia Volatilization From European Livestock Manure Management Systems

Frontiers in Sustainable Food Systems, 2019
The largest source of ammonia (NH3) emissions to the atmosphere is NH3 from agriculture, the majority of which arise from livestock manure. The NH3 emitted is a threat to human health through the formation of fine particles, causes eutrophication of ...

Identification and genomic analysis of a thermophilic bacterial strain that reduces ammonia loss from composting

Microbiology Spectrum
Ammonia loss is the most severe during the high-temperature stage (>50°C) of aerobic composting. Regulating ammonia volatilization during this period via thermophilic microbes can significantly improve the nitrogen content of compost and reduce air ...

Unraveling Quantitative Sensing Mechanism and Predictive Molecular Metrics for High‐Performance OFET Amine Sensors

Advanced Functional Materials, EarlyView.
This study introduces a novel chloro boron subphthalocyanine/polymer blend OFET sensor achieving 0.005 ppb limit of detection for ammonia at room temperature and high selectivity against similar amines. An original theoretical framework is proposed to describe the sensing mechanism, relating analyte molecular volume and Lewis basicity to sensor ...

Ammonia volatilization from a piggery pond

Water Science and Technology, 1996
There is a need to improve the performance of agricultural wastewater stabilization ponds. In particular, a better understanding of the relative importance of the nitrogen removal mechanisms is required. The objective of this study was to quantify the magnitude of ammonia volatilization from a piggery pond in order to determine its significance as a ...
