Studies on Relationship Between Season and Inorganic Elements of River Soan at Dhoak Pathan Bridge (Chakwal), Pakistan

Furhan Iqbal, Muhammad Ali, Abdus Salam and Younas Kohkar    

Abstract: The present study was designed to demonstrate the seasonal variations in inorganic elements of River Soan at Dhoak Pathan Bridge, for a period of eight months from May 2001 to December 2001. Water samples were collected on monthly basis and different metals were detected through atomic Absorption Spectroscopy. The levels of Zn and Mg concentrations were below the detection limit. Na concentration was maximum in May (168.75 ppm) and minimum in July (22.5 ppm). K concentration was maximum in December (12.31 ppm) and minimum (3.94 ppm) in August. Ca concentration was maximum in May (34.25 ppm) and minimum in October (4.25 ppm). Maximum variation was observed in case of Sr. Sr was not detected in May and July while maximum (0.47 ppm) Sr was detected in November and minimum (0.04 ppm) in June. The overall levels of inorganic elemental concentrations were within the safe limits at the sampling site throughout the study period.
