What is it about?
iqABSTRACTThis study evaluated the sediment quality of the Main Outfall Drain River in Thi-Qar Government by measuring (Mn, Ni, Pb, Fe, Cr, Zn, Cd, and Cu) in the sediments. Samples were collected at 4 locations between the summer of 2021 and the winter of 2022, and the results revealed that the heavy metal dominance in the Main Outfall Drain and Al-Sanaf Marsh was in the order of Fe> Mn> Ni> Zn> Cr> Pb>Cu>Cd. Among these sedimentary contaminants, Fe has the highest level in sediments. Two indices were used: sediment quality criteria (QSm) and pollution index (PI).

Why is it important?
The main goal of this study was to determine the sources of heavy metals in sediments of the Main Outfall Drain and Al-Sanaf Marsh, which is one of the southern marshes in Iraq, in addition to evaluating the toxicity of heavy metals in the sedimentary part of the river.
Perspectives
The study showed that the sediment quality in the considered area was low. The results give suitable information about the possible factor that may influence the quality status of sediments for the studied water body. Heavy metal dominance in the Main Outfall Drain and Al-Sanaf Marsh was in the order of Fe > Mn > Ni > Zn > Cr > Pb > Cu > Cd. Among these sedimentary contaminants, Fe has the highest level in sediments as a result of industrial wastewater from smelting factories in the study area.
