英文摘要 | Fifteen hydrolyzed amino acids (THAA) were quantified in urban aerosols (TSP samples) collected during April 2012 to May 2013 in Beijing, China using high-performance liquid chromatography (HPLC) after their derivatization with o-phthalaldehyde (OPA), to investigate their molecular distributions and seasonal variation. Total concentrations of amino acids ranged from 1.73-25.7 nmol m(-3) with a peak in spring (13.7 nmol m(-3)), followed by winter (11.5 nmol m(-3)), fall (9.51 nmol m(-3)) and summer (7.45 nmol m(-3)). Glycine (Gly), alanine (Ala) and valine (Val) are found to be the most abundant species, which account for 46% of the total THAA. Compared with those recorded in previous studies, the atmospheric levels of amino acids in Beijing were higher than those from other regions. Enhanced amounts of methionine, tyrosine, histidine, aspartic acid and glutamic acid were found during the rainfall events. The factor analysis further suggests that amino acids in urban Beijing originated from multiple sources including biological emission, biomass burning, as well as anthropogenic activities. |
