“…A hot spot of TMA‐containing particles appeared in the area near YSP. Many studies have reported the emission of MMA from land activities, such as industry (Fuselli et al, 1982), automobiles (Cadle et al, 1980), sewage (Abalos et al, 1999), and biomass burning (Ho et al, 2015; Schade et al, 1995b). In the container ports in Southern California, OC particles containing distinct TMA markers ( 59 (CH 3 ) 3 N + ) were detected, suggesting that ports are an industrial source of amines (Gaston et al, 2013b).…”

Single-particle aerosol mass spectrometry was employed during a cruise campaign from 3 to 27 June 2017 to investigate the mixing states and sources of amine-containing particles in the East China Sea. A total of 271,160 particles were successfully identified, and 19,861 of these particles contained amines. Monomethylamine (MMA), trimethylamine (TMA), and diethylamine (DEA) were the most abundant amines. They accounted for 50%, 16%, and 29%, respectively, of the amine-containing particles. The size distributions (mean ± geometric standard deviation) of the MMA-, TMA-, and DEA-containing particles peaked at 0.58 ± 0.12, 0.56 ± 0.10, and 0.40 ± 0.10 μm, respectively. Using an adaptive resonance theory neural network algorithm, four major clusters of amine-containing particles were categorized: carbon-rich particles, K-rich particles, Na-rich particles, and metal-rich particles. The MMA-containing particles contained abundant elemental carbon-, K-, Mn-, and Fe-rich particles, which exhibit higher concentrations in land air masses, indicating that the MMA mainly originated from terrestrial anthropogenic sources. The TMA-containing particles contained abundant organic and elemental carbon-, EC-, K-, and V-rich particles. High concentrations of TMA-containing particles were measured near ports, indicating the significant contribution of the ports. The DEA-containing particles contained abundant organic and elemental carbon-, K-, Mn-, Cu-, and Na-rich particles, and high concentrations of DEA-containing particles were observed in remote marine areas, suggesting that both terrestrial anthropogenic and marine sources are important contributors to DEA-containing particles.

“…(Rabaud et al, 2003). Individual concentrations for the three methyl-substituted amines of up to a few 10 12 molecule cm −3 were detected in an industrial area (Fuselli et al, 1982). Much higher concentrations can be expected in the vicinity of power plants with subsequent CO 2 capture using amines as the working fluid (Karl et al, 2009).…”

Enhancement of atmospheric H2SO4 / H2O nucleation: organic oxidation products versus amines

et al. 2014

Abstract. Atmospheric H 2 SO 4 / H 2 O nucleation influencing effects have been studied in the flow tube IfT-LFT (Institute for Tropospheric Research -Laminar Flow Tube) at 293 ± 0.5 K and a pressure of 1 bar using synthetic air as the carrier gas. The presence of a possible background amine concentration in the order of 10 7 -10 8 molecule cm −3 throughout the experiments has to be taken into account. In a first set of investigations, ozonolysis of olefins (tetramethylethylene, 1-methyl-cyclohexene, α-pinene and limonene) for close to atmospheric concentrations, served as the source of OH radicals and possibly other oxidants initiating H 2 SO 4 formation starting from SO 2 . The oxidant generation is inevitably associated with the formation of organic oxidation products arising from the parent olefins. These products (first generation mainly) showed no clear effect on the number of nucleated particles within a wide range of experimental conditions for H 2 SO 4 concentrations higher than ∼ 10 7 molecule cm −3 . Also the early growth process of the nucleated particles was not significantly influenced by the organic oxidation products in line with the expected growth by organic products using literature data. An additional, H 2 SO 4 -independent process of particle (nano-CN) formation was observed in the case of α-pinene and limonene ozonolysis for H 2 SO 4 concentrations smaller than ∼ 10 7 molecule cm −3 . Furthermore, the findings confirm the appearance of an additional oxidant for SO 2 beside OH radicals, very likely stabilized Criegee Intermediates (sCI). A second set of experiments has been performed in the presence of added amines in the concentrations range of a few 10 7 -10 10 molecule cm −3 applying photolytic OH radical generation for H 2 SO 4 production without addition of other organics. All amines showed significant nucleation enhancement with increasing efficiency in the order pyridine < aniline < dimethylamine < trimethylamine. This result supports the idea of H 2 SO 4 cluster stabilization by amines due to strong H 2 SO 4 ↔ amine interactions. On the other hand, this study indicates that for organic oxidation products (in presence of the possible amine background as stated) a distinct H 2 SO 4 / H 2 O nucleation enhancement can be due to increased H 2 SO 4 formation caused by additional organic oxidant production (sCI) rather than by stabilization of H 2 SO 4 clusters due to H 2 SO 4 ↔ organics interactions.

“…Kuwata et al (1983) trapped amines with Sep-Pak C,, (SP) cartridge and eluted them with methanol-water mixture before GC. Kashihira et al (1980) used Tenax GC as a sorbent whereas Fuselli et al (1982) used activated charcoal. In both methods trapped amines were thermally desorbed for analysis.…”

Trimethylamine (TMA) concentration in fish tissue is an accepted measure of deterioration. In this preliminary study a direct relation was demonstrated between TMA in the tissue and in the headspace above the fish flesh. A relatively simple but precise procedure was developed for measuring TMA headspace concentration, based on air sampling with Carbotrap or Tenax sorbent tubes and subsequent thermal desorption and gas chromatographic (GC) analysis. Sampling and analysis are completed in less than 5 min. Fish freshness determined by TMA headspacc analysis was consistent with grading estimated by sensory tests, but the instrumental method provided a more objective and quantitative assessment of quality and an estimation of postmortem age of the fish.
