Abstract
The increasing numbers of contaminated sites
within residential areas in Bauchi metropolis could result in serious
environmental pollution and health risks to humans. This study was conducted to
assess the impact of auto-mechanic activities on the surrounding environment. Soil
samples were collected at the depth of 30cm and analysed using the Atomic
Absorption Spectrophotometer. All the metals investigated were present in the
soil at very high concentrations compared to their background samples, World
Soil Average and the Department of petroleum resources target values. The range
of the calculated geoaccumulation indices for the study metals were Cd: 1.000 –
90.32, Cr: 1.150 – 11.216, Cu: 0.554 – 3.882, Pb: 1.00 – 31.976, Mn: 1.312 –
4.170, Ni: 0.000 – 4.772, while the pollution indices results for each metal
ranged from 0.000 for Ni to 450.00 for Cd, indicating different pollution
levels. The Pollution load indices (PLI) for the various study sites were all
extremely high (PLI > 1) and followed the hierarchical order NJ (23.96) >
AB (21.31) > YT (10.00) > JR (5.26). With these high levels of pollution,
the auto-repair sites therefore constitute a serious threat to their environs
and should as a matter of urgency be re-developed or relocated very far from
residential areas.
