CONCENTRATION OF HEAVY METALS IN SOIL FROM THE VICINITY OF WASTE DUMPSITES IN GOMBE METROPOLIS......

The presence of heavy metals in soil near dumpsites in Gombe metropolis was investigated in this study. Twelve samples were taken from four distinct dumpsites in Gombe town: Pantami (P), Jekadafari (F), Madaki (D), and Malam inna (M) in Gombe metropolis at distances of 50, 100, and 150 metres, respectively, and a control sample was taken from Gombe State University. The samples were digested in a 1:5:1 mixture of perchloric acid, nitric acid, and sulphuric acid before being examined with an atomic absorption spectrophotometer (AAS). In the order Fe >Zn>Cu>Cd>Pb, the components examined reveal mean heavy metal concentrations in the range of 6.923 to 40.00 ppm, Pb: 0.079 to 0.38 ppm, Cd: 0.274 to 4.444 ppm, Zn: 9.00 - 25.50 ppm, and Cu: 1.481-5.926 ppm. Along Pantami, Jekadafari, Madaki, and Mallam Inna, all of the metals tested showed significant increases in the soil as one moved further away from the dumpsite. The study's findings show that there is no significant risk of pollution or contamination.
