| Abstract: | Based on Total Suspended Particulates (TSP) observations of Tazhong, Tikanli, Kashi and Minfeng in 2009, combined water-soluble inorganic ion analyses, this paper studied the spatial and temporal distribution of TSP in the Tarim Basin and analyzed concentration characteristics. The results are as follows: (1) monthly average TSP concentrations shows a similar trend in Tazhong, Tikanli, Kashi and Minfeng with peak values in April-May and low values in November-December. As for the quarter average mass concentration trends, spring has the highest value, followed by summer and autumn, and winter is the lowest; (2) total annual concentration trend of water-soluble inorganic ions in TSP is as follows: Tazhong > Tikanli > Minfeng > Kashi. SO42- concentrations are 58%, 50%, 54% and 51% of total ion concentration; Ca2+ concentrations are 13%, 16%, 16% and 11%; Na+ concentrations are 12%, 13%, 10% and 12% and Cl- concentrations are 12%, 16%, 11% and 22%, respectively. Therefore, sulfate, calcium, sodium and chloride ions are the main inorganic components of TSP in the Tarim Basin; (3) the correlation coefficients of anions and cations in Tikanli, Minfeng, Kashi and Tazhong are 0.99, 0.99, 0.25 and 0.91, respectively; the average anion concentrations are 2.57, 2.12, 2.15 and 3.02 times the average cation concentrations, indicating that ions were unbalanced; (4) SO42-/NO3- ratio is much larger than the ratio of coal-fired emissions SO42-/NO3-, thus the impact of fixed emission sources in the four regions on the atmosphere is far greater than that of mobile emission sources. |
