In order to assess the relationships between iodine isotopes (I-127, I-129) and atmospheric elements, the concentrations of chlorine and bromine were determined using high resolution inductively coupled plasma mass spectrometry with an X SeriesII ICPMS (Thermal Electron Corporation) machine for precipitation samples collected during the period 2000-2006 at three different stations (Abisko, Uppsala and Kvidinge) in Sweden. For concentration of chlorine, Abisko in the north has the lowest average concentration, 0.6 mg/L, Kvidinge showing a little higher, 1.13 mg/L, and Uppsala exhibits as the highest concentration, 2.93 mg/L. As to bromine, the median concentration was 3.07, 3.43 and 4.73 mu g/L for station Abisko, Uppsala and Kvidinge, respectively. Chlorine and bromine show the highest correlation with I-127 in Kvidinge (r < 0.7) than those in Uppsala and Abisko. The different correlations of I-127-Cl and I-129-Cl, or I-127-Br and I-129-Br are attributed to their respective sources to the atmosphere. Furthermore, the results show that iodine isotopes (I-127, I-129) have high correlations with Cl and Br than the other atmospheric elements.
