The Effect of Trimethylamine on Atmospheric Nucleation Involving H2SO4
Field observations and quantum chemical calculations have shown that organic amine compounds may be important for new particle formation involving H2SO4. Here, we report laboratory observations that investigate the effect of trimethylamine (TMA) on H2SO4-H2O nucleation made under aerosol precursor concentrations typically found in the lower troposphere ([H2SO4] of 106−107 cm−3; [TMA] of 180–135...
متن کاملOn the formation of sulphuric acid – amine clusters in varying atmospheric conditions and its influence on atmospheric new particle formation
Sulphuric acid is a key component in atmospheric new particle formation. However, sulphuric acid alone does not form stable enough clusters to initiate particle formation in atmospheric conditions. Strong bases, such as amines, have been suggested to stabilize sulphuric acid clusters and thus participate in particle formation. We modelled the formation rate of clusters with two sulphuric acid a...
متن کاملTrimethylamine N-oxide in atherogenesis: impairing endothelial self-repair capacity and enhancing monocyte adhesion
Several studies have reported a strong association between high plasma level of trimethylamine N-oxide (TMAO) and atherosclerosis development. However, the exact mechanism underlying this correlation is unknown. In the present study, we try to explore the impact of TMAO on endothelial dysfunction. After TMAO treatment, human umbilical vein endothelial cells (HUVECs) showed significant impairmen...
متن کاملThe biosynthesis of trimethylamine-N-oxide.
Norris and Benoit (1) provided ‘good evidence that injected trimethylamine is converted in the rat to its N-oxide and excreted in the urine. Other mammals have been shown to have the ability to effect the same reaction (2, 3). In a preliminary communication (4), we have reported that hog liver microsomes will catalyze the oxidation of trimethylamine in vitro. The additional requirement for redu...
