Abstract: Heavy Metals are any metallic element that has a relatively high density and is toxic or poisonous at low concentration. Heavy Metals are general collective term, which applies to the group of metals and metalloids with atomic density greater than 4 g/cm3. Most of these metal ions can be released from industries, agriculture and individual household and are in simple cationic forms. This study aimed at determining some heavy metals contents in dump soil along Federal College Education (F.C.E.) Katsina. Three samples each were collected differently at the vicinity of the tannery and the surrounding tanneries, 10m away a nearby farms and nearby growing plants. Control samples was also collected far away from these areas for comparison. A distance between 5 to 10 m was maintained between each sampling point to study the metal distribution of the study area. Atomic Absorption Spectrophotometer (AAS) with air acetylene flame was used for the metal analysis. The results of the three samples studied obviously indicates that all the soil samples have Manganese concentration in the in the highest degree (A 3.83 mg/kg, B 3.652 mg/kg, C 6.602 mg/kg) while Co: 0.048 mg/kg, Cd: 0.028 mg/kg, Cd: 0.026 mg/kg) respectively indicates lowest concentration in the three samples. All of the soil samples contain high manganese concentrations and other heavy metals are present in negligible amounts. This means that manganese-containing waste is circulating in our environments at random. Contamination or soil pollution caused by high manganese concentrations in our environment is extremely dangerous since it puts domestic animals’ and humans’ health at risk.
