دراسة بعض الخصائص الفيزيوكيميائية والمايكروبية للمياه المعباة المنتجة محليا والمستوردة في مدينة بغداد

Study of Some Physiochemical and Microbial Properties of Local and Imported bottled Water in Baghdad City

The physiochemical and microbial properties and the percentage of failure in the application of physiochemical and sanitary demands which is stated in confirmed Iraqi standards were studied for 400 local and imported bottled water samples which is the most used in Baghdad city. The results of this study clarified the rising in values and concentrations of turbidity, pH, electrical conductivity, total dissolved solids. total hardness, calcium, magnesium, lead, and iron in local samples in the comparison with the imported one; while the monthly average of chloride concentrations were rising in imported samples in the comparison with local samples which recorded the highest percentage of failure in the application of sanitary demands .While the imported samples recorded the highest percentage of failure in the application of physiochemical demands. The results of this study clarified the presence of high significant positive correlation among the studied microbial properties and high significant negative correlation between these properties and lead concentrations averages and between the last one and pH values averages.
