| Abstract: | Atmospheric TSP was figured by transmission electron microscope. K, Na, Ca, Mg were determinde by flame atomic absorption spectrometry and the detection limit were 0. 105, 0. 124, 0. 259, 0. 237 mg/kg respectively. Correlation coefficients were not less than 0.997 9, the recoveries were in the range of 90.0% - 95.0% and the relative standard deviations of samples were 0.6% -2.1%. |
