Description
Summary:The present study reports the chemical composition and atmospheric salt load rainwater of Mosul city/ Nineveh Governorate / Iraq. The sampling were done from October 2012 to March 2013. Twenty six samples were collected and analyzed for pH, ion concentration (Ca<strong><sup>++</sup></strong>, Mg<strong><sup>++</sup></strong>, K<strong><sup>+</sup></strong>, Na<strong><sup>+</sup></strong>, CI<strong><sup>-</sup></strong>, HCO<strong><sub>3</sub><sup>-</sup></strong>, SO<strong><sub>4</sub><sup>--</sup></strong>) and electrical conductivity. Total rainwater was 338.55mm. The results show that the volume weighted mean (VWM) pH and electrical conductivity in the rainwater were 6.83 and 114.22µS.cm<strong><sup>-1</sup></strong> respectively. Cation and anion concentration took the  following order : Ca<sup>++</sup> ˃ Mg<sup>++</sup> ˃ Na<sup>+</sup> ˃ K<sup>+ </sup>and HCO<sub>3</sub><sup>-</sup> ˃ CI<sup>-</sup> ˃ SO<sub>4</sub><sup>=</sup>.  HCO<sub>3</sub><sup>-</sup> and Ca<sup>++</sup> contributed 65.3% of the total ions in the rainwater. Equivalents ratios for different ionic components to sodium, revealed higher values in rainwater than that of seawater. This indicates the dominance of non-marine in studied samples. Analyses  revealed  that loads delivered from the fallen precipitation in the urban city of Mosul was about 0.1167kg cl<sup>-</sup>/m<sup>3</sup> of chloride in rainwater  which equal numerically to 395kg  NaCI. h<sup>-1</sup> of land.
