HEALTH RISK ASSESSMENT OF SOME HEAVY METALS IN SOIL SAMPLES AROUND IDENTIFIED METAL WORKSHOPS

Soil properties may change due to climate change, but in recent times, the changes occur as a result of anthropogenic activities such metal workshop operations. This study was conducted assess impact contamination on human health operating workshops. In this research work which carried out estimated risk heavy around workshops, five different Garejin Oga Abdul (GOA), Nakowa Welding Construction (NWC), Da’awa (GDH), Adamu Salisu (GAS) and Iliya Maina (GIM) all Potiskum town, Yobe State were sampled for analyzed eight metals (Pb, Zn, Cr, Cd, Co, Mn, Ni Cu) levels using Atomic Absorption Spectrophotometer (AAS). Results from revealed that Cr (2.37E-01) Co (5.77E-04) recorded highest lowest hazard quotient trend total is > Pb Mn Cu Cd Zn Co. The Quotients (HQ) Hazard Index (HI) deduced workshops fall below acceptable level indicating unlikelihood non-carcinogenic risks. However, GDH, GIM GOA pose medium cancer risks with Incremental Lifetime Cancer Risk (ILCR) values 8.195 x 10-5, 6.313 10-5 7.443 respectively.
