Abstract: To the best of our knowledge, no measurements of airborne particles have previously been carried out in the city of Linfen, Shanxi Province, China.
Size-resolved aerosol mass and elemental compositions were measured in the urban background environment during the Linfen Air Quality Study.
Weekly samples were collected for three months from October 2019 to December 2019. A Tisch Ambient Eight-Stage Cascade Impactor was used to collect aerosol samples of fine particulate matters smaller than 10 µm; also, a 400 mesh hexagonal Agar SEM grid was used to sample particles to carry out SEM analyses. Approximately 78% of samples contain aerosol particles below 7 µm, which means the aerosol particles are respirable. Approximately 25% of samples contain aerosol particles below 2 µm, which means the aerosol particles can reach the alveoli of the lung. These are harmful to human health if they consist of dangerous particulate matters. SEM analyses show the following elements which are presented in the particulate matter of Linfen urban air: Mg (MgO), Al (Al2O3), Si (SiO2), S (FeS2), K, Ca, Cu, Fe, Ag, and Ti. Our study cannot verify whether these elements are hazardous in Lifen’s aerosol.
