Determination some heavy metals in sediments of shatt al-hilla river by using modified single chemical fractionation technique

الملخص EN

Surfacial sediment composite samples were collected from six main sampling stations at Shatt Al-Hilla River from Khafaja area to Betta bridge in Babylon province.

A four-step modified single sequential extraction procedure was used to determine heavy metal (Pb, Ni, Fe and Cu) chemical phases in the sediment samples.

The results showed that there was concentrated for the high values of total concentrations of studied heavy metals in the station (5).

When comparing the percentage of heavy metals in exchangeable and carbonate fractions at studied stations with risk assessment code we noted that the Ni, Fe and Cu were located within the degree : No risk.

while Pb metal was within the degree : Low risk which indicates the dominance of anthropogenic sources effect.
