英文摘要:
Low-molecular-weight aliphatic amines were measured in the ambient urban background air at the SMEAR III station (Station for Measuring Forest Ecosystem-Atmosphere Relations III) in Helsinki, Finland, from May until late August 2011. The alkyl amines measured were dimethylamine (DMA), ethylamine (EA), trimethylamine (TMA), propylamine (PA), diethylamine (DEA), butylamine (BA) and triethylamine (TEA).Of these amines, DMA+EA and TMA+PA were the most abundant, with average concentrations of 24 and 8ppt. The ranges of weekly mean concentrations of DMA+EA and TMA+PA were
