  • Abstract:

The contribution of vehicular emission to the levels of copper (Cu), molybdenum (Mo) and antimony (Sb) in roadside soil along Akure-Owo highway in Ondo state was investigated. Soil samples were collected at 0-20cm depth at 2m, 30m and 60m away from the edge of the road. Soil digestion was done using the mixture of HNO3 and HCl in ratio 3:1 in microwave oven (MLS 1200) set at: 5 min 300W, 2 min 600W, and 5 min 300W and 10 min respectively. Heavy metal quantitative analysis was carried out using inductively coupled plasma – emission Atomic spectrometry (ICP – AES).Cur concentration in soil samples ranged from 3.5 to 17.0 µg/g, Sb ranged from ND to 15.0 µg/g, while Mo ranged from 125 to 95 0µg/g. The information obtained from this analysis shows the presence of these metals in the road soil investigated, hence can be used as fingerprint tools to identify the contribution of on-road vehicles to traffic related metal pollution.
