The limited availability of ammonia (NH3) measurements is currently a barrier to
understanding the vital role of NH3 in secondary aerosol formation during haze pollution …

Emissions of reactive nitrogen (N) species can affect surrounding ecosystems via
atmospheric deposition. However, few long-term and multi-site measurements have focused …

Urban NH3 concentrations were mapped in Barcelona (Spain) by means of passive
samplers (dosimeters). Average NH3 levels were 9.5 μg m− 3 in summer and 4.4 μg m− 3 in …

Identifying the sources of increased ammonia (NH 3) in the atmosphere has important
implications for air quality, ecosystems, and climate. While analysis of the nitrogen isotopic …

It is well established that in environments where NH 3 abundance is limiting in secondary
PM 2.5 generation, a reduction of NH 3 emissions can result in an important contribution to …

Stringent mitigation measures have reduced wintertime fine particulate matter (PM 2.5)
concentrations by 42.2% from 2013 to 2018 in the Beijing-Tianjin-Hebei (BTH) region, but …

In this study, a microwave discharge electrodeless lamp (MDEL) photo-degradation system
coupled with anatase TiO 2 (P25) was constructed to improve the selective degradation of …

Dielectric-barrier discharge (DBD) in argon as a cold source is used for the excitation of
gaseous inorganic small molecules at atmospheric pressure. By choosing ammonia as a …

A diffusive sampling device, the DSD-NH3, has been developed for measurement of
ammonia in air. The DSD-NH3 comprises silica gel impregnated with phosphoric acid as the …

This study focuses on assessing the indoor air quality in a storage room (SR) belonging to
Museo Nazionale Scienza e Tecnologia Leonardo da Vinci in Milan (MUST), covering …
