In the summer of 1995, samples of airborne particles were collected in the Amman area of Jordan. Ion chromatography (IC) was used for the determination of anions in these samples. Four anions were identified and quantified in the atmosphere of Amman. The concentration ranges of F-, CL-, NO3- and SO4= were 0.04 - 3.3, 2.25 - 15.7, 1.96 - 8.39 and 16.88 - 41.33 mu g/m(3), respectively. The study shows that Cl-, NO3-, and SO4= are the major anions of air particulate, and the concentration of SO4= exceeds that of some other cities worldwide. The total suspended particles (TSP) value was determined to be 66 to 326 mu g/m(3).
