“…5, schematically demonstrating the fate of NH 3 and TMA in ruminants. As already indicated by Schade and Crutzen (1995), the primary source for TMA is the rapid microbial degradation of choline (Davies, 1936;Eddy, 1953;Neill et al, 1978;Zeisel et al, 1989;Bain et al, 2005;Wang et al, 2011;Craciun and Balskus, 2012) taken up with the feed (Pinotti et al, 2002). In addition, rumen microorganisms might metabolise TMA from dietary supply of carnitine, betaine, and TMAO (Davies, 1936;Mitchell et al, 1979;Zhang et al, 1999).…”

Abstract. Degradation of plant material by animals is an important transformation pathway in the nitrogen (N) cycle. During the involved processes, volatile reduced alkaline nitrogen compounds, mainly ammonia (NH3) and aliphatic amines such as trimethylamine (TMA), are formed. Today, animal husbandry is estimated to constitute a main source of aliphatic amines in the atmosphere with TMA being the main emitted compound. Here, we show how the interaction between faeces and urine in animal production systems provides the primary source for agricultural TMA emissions. Excreted urine contains large quantities of urea and TMA-N-oxide, which are transformed into NH3 and TMA, respectively, via enzymatic processes provided by microbes present in faeces. TMA emissions from areas polluted with urine–faeces mixtures are on average of the order of 10 to 50 nmol m−2s−1. Released amines promote secondary aerosol particle formation in the agricultural emission plume. The atmospheric lifetime of TMA, which was estimated to be of the order of 30 to 1000 s, is determined by the condensation onto aerosol particles.

“…Since the degradation of methylamine on the surface of the photocatalyst follows a pseudo-rst-order reaction, the relationship between concentration and reaction time can be described by eqn (2). 39 Plotting the data and tting the curve allows determination of the rate constant for the degradation reaction of methylamine.…”

“…Methylamine is very odorous; it has a low odor threshold and a strong shy odor. 1,2 The odor problems caused by the emission of MA have led to social issues, negative impacts on human health, local economies, and have consequently attracted much attention. [3][4][5] To solve the malodor problem, physical and chemical methods have been widely used.…”

Hydrogen titanate nanotubes (H-TNTs) were fabricated via a hydrothermal approach, followed by calcination, to obtain a series of titanate nanotubes (TNTs). The prepared (H−)TNTs were applied in the photocatalytic degradation of methylamine (CH3NH2). The H-TNTs calcined at 350 °C (TNTs-350) showed the best photocatalytic activity of over 85% within 3 h. Experimental results indicated that the surface acidic sites and the crystalline phase are key factors that influence their photocatalytic activities. Although H-TNTs possess abundant surface hydroxyl groups and acidic sites, which favor the adsorption of CH3NH2, enhanced photocatalytic performance is obtained by balancing the number of acidic sites and the anatase TiO2 quantity.
