Mesopotamian Journal of Marine Science,
Volume 23, Issue 2, Pages 279-286
AbstractCu, Fe, Mn & Ni trace metals in falling dust were estimated in seven selected locations in Basrah governorate, Southern Iraq, 1- Qurna, 2-Al- Ma'aqil, 3-Shatt Al-Arab Sector, 4- Abu Al-Khaseeb, 5-Al-Fao, 6 -Al-Zubair, & 7- Safwan. Samples were collected for the period March-April 2007, and trace metals were determined by atomic absorption technique after digestion treatments with mixed acids of HNO3 & HClO4. The highest concentrations of trace metals recorded were, 9312.68 ppm (Fe) in Qurna, 350.17 ppm (Cu) in Al-Ma'aqil, 300.79 ppm (Mn) in Qurna and 76.31 (Ni) in Al-Ma'aqil, while lower values were 0.25 ppm (Cu) in Safwan, 2256.98 ppm (Fe) in Al-Zubair, 178.03 ppm (Mn) in Abu Al-Khaseeb and ND (Ni) in Al-Fao. Cu, Fe, Mn & Ni were highly correlated with each other.
