Abstract
The Jeneberang River flows between settlements, rice fields, traditional ports which are located in the southernmost part of Makassar. Regional development and increasing population are anthropogenic as a source of heavy metal input to rivers, and require a sustainable geochemical study of the environment. Study objectives, concentration and spatial distribution, use of sediment samples for grain size and Coupled Plasma-Osiloscope Emission Spectroscopy (ICP–OES) method for trace elements. The average yield of the seven river sediment samples was (Cr)149 mg kg-¹ (Mn)1388.14 mg kg-¹, (Cd)0.74 mg kg-¹, (Cu)54.71 mg kg-¹, (Zn)130.28 mg kg- , (Pb)3675 mg kg-1.
 The conclusion on the grain size of the sand, it is known that the order is dominated by concentration: Mn>Zn>Cr>Pb=Cu then changes to the grain size of silt clay: Mn>Cr>Zn>Cu>Pb, showing indications of migration, exchange phase and heavy metal enrichment. The order of heavy metal contamination uses the Igeo average value: Cd>Cr=Pb>Mn>Cu>Zn is class 1, namely 0 < Igeo < 1 = not polluted to moderately polluted, and the order of heavy metal enrichment uses EF: Cu (0.64), Mn (0.58), Pb (0.56), Zn (0.73), Cd (0.41), Cr (0.55), generally EF < 2 is deficiency to minimal enrichment. It seems that the heavy metals in the minimum contamination and enrichment criteria which are strengthened by statistical analysis of correlation factors and multiple scatter are Pb and Zn.
