| Abstract | ||
| For the period of Dec. 2001– Jan. 2002, wet samples of rain water were collected from different sites covered the industrial sites of petrochemical company in southern Iraq. The samples were analysed for pH, conductivity, chloride, sulphate, calcium, magnesium, bicarbonate and phosphate concentrations. Lower pH recorded were 6.5 in the petrochemical company while maximum value recorded was 7.6 in the atmosphere of paper and mill company. For chloride lower value recorded was 35.45 mg/l in Shuaiba site and maximum value was 106.4 mg/l in Umm Qaseer. These values were accompanied with electric conductivity of 0.02 mS/cm in Shuaiba and maximum value of 0.72 mS/cm in Umm Qaseer . Calcium and magnesium ranged between 0.1-2 mg/l and 0.0 – 1.16 mg/l respectively. Sulphate ranged from 16.4 mg/l in petrochemical company to 11.93 mg/l in Basrah city. Bicarbonate was high and ranged between 61.0 mg/l in Shuaiba and 109.8 mg/l in Zubair town. For phosphate values were low and ranged from 0.50 μg at.P-PO4P 3- P/lP Pin BasrahP Pcity to 1.26 μg at.P-PO4P 3- P/lP Pin Petrochemical company. Wet precipitation in southern Iraq showed moderate values of pH with slight acidity due to industrial emissions of N and S, and slight basic due to the dust from the land of basic characteristics. | ||
