Abstract The surface sediment and surface soil samples were taken from the River Nile (Abroof, Shambat, AL-Halfaia, and AL-Hetana), Khartoum, to determine the available levels of Lead (Pb), Zinc (Zn), and Cadmium (cd) to establish a baseline concentration of each of these available metals, and to investigate their possible correlations with soil and sediment properties. The content of each of the three heavy metals in soil and sediment samples was determined using atomic absorption spectroscopy, AAS.The values of Zinc in the soil and sediment samples, were found to be between (0.192 to 0.294 ppm) and (0.101 to 0.181) respectively, showing the highest content in soil and sediment samples in Shambat (S) and Abroof (A), and the lowest values recorded for samples in AL-Halfia (H) and AL-Hetana (E). While Lead content was ranged between (0.105 to 0.136 ppm) for soils samples (AL-Hetana(E) and Shambat(S)), and (0.078 to 0.141) for sediment samples (Abroof(A) and shambat (S)). Whereas, content for Cadmium ranged between (0.010 to 0.015 ppm) for soil samples Shambat, AL-Hetana and Abroof and (0.011 to 0.016) for sediment samples Shambat, AL-Halfia and Abroof.Soil and sediment physicochemical properties (pH, temperature & conductivity) were found to be correlated with the available heavy metals content, suggesting that the enhanced mobility of heavy metals are related to anthropogenic activities, the high percentage of organic carbon in soil (11.6%) and sediment (15.0%).

A co-precipitation technique for nickel(II), chromium(II), manganese(II), lead(II) and zinc(II) with the aid of copper(II) cyclo-hexylmethyldithiocarbamate was established. The influences of some analytical parameters such as pH, sample volume, amounts of cyclo-hexylmethyldithiocarbamate and copper(II) on the recovery of metal ions were investigated. The heavy metals in the precipitate were determined by flame atomic absorption spectrophotometry. The range of detection limits for the heavy metals was 0.003–0.005 mg/L. The atomic spectrometric technique with co-precipitation procedure was successfully applied for the determination of Ni, Cr, Mn, Pb and Zn in industrial wastewater and sediment samples from Ladipo stream in Lagos, Nigeria. The mean concentrations for these metals using co-precipitation procedure were not significantly different from corresponding concentrations obtained using spectrometric techniques without co-precipitation procedure.

Heavy metal concentration in roadside soil and plants are increasingly becoming of health concern. This work determined the concentration of selected heavy metals (Cd, Pb, Zn, Cr, Fe, Mg, Mn, Co, Ni and Cu) in roadside soils and plants samples from selected sites (Plaifu, Shiwa, Fadama-rake and Damdrai) along major road in Hong. Soil samples were taken 10 m, 20 m and 30 m away from the edge of the road at the  depth of 0-10 cm, 10-20 cm and 20-30 cm. Plant samples were randomly collected within the vicinity where the soil samples were taken and were analysed using Atomic Absorption Spectrophotometer. The result revealed the trend in soil heavy metal concentration was Fe > Mn > Mg > Pb > Zn > Ni > Co > Cu > Cr > Cd and for plant the trend was Fe > Mn > Mg > Zn > Pb > Ni > Cu > Cd > Co > Cr. The concentrations decreased with increasing distance away from the edge of the road as well as with depth at which the soil sample were taken. The transfer factor showed that the concentration of Zn, Mn, Cu and Mg were greater than 1, which shows that plant were enriched by Zn, Mn, Cu and Mg from the soil. Mg and Cd equal to 1 at Plaifu and Damdrai. Most of the values of TF at the study area super pass 0.5, which implies that generally, the ability of bioaccumulation of these heavy metals in examined plants were relatively high.
