A study was conducted to investigate deposition of environmental contaminants in bushmeat with emphasis on some heavy metals {Nickel (Ni), Lead (Pb), Cupper (Cu) and Cadmium (Cd)}. The major bushmeat markets on these highways were studied in terms of their distance to the highways, traffic volume (TV) and land uses. Face-to-face interview was also conducted with one hundred and twenty processed bushmeat buyers on these highways to determine the most commonly preferred processed bushmeat while the concentrations of Ni, Pb, Cu and Cd in the three most commonly purchase processed bushmeat identified were determined using Atomic Absorption Spectrophotometry. It was revealed that the average distance of the market at {Ibadan-Lagos (IL)Ibadan-Ife (IF), Ore-Sagamu (OS) and Abeokuta-Ibadan (AI)} were 6.70m, 3.50m and 10.20m, respectively. TV followed IL>OS>IF>AI trend. Heavy metals examined were present in the three commonly purchased processed bushmeat (Grasscutter, Duiker and Monitor-lizard) at varying levels. Pb concentration in grasscutter (0.01±0.01mg/kg) at OS was lower than the maximum permissible level (MPL) while the concentrations of Ni, and Cd in duiker at IF (0.06±0.09mg/kg) and AL (0.06±0.05mg/kg), respectively were higher than the MPL. The concentrations of the verified heavy metal in these bushmeat had significant effects (p< 0.05) on the distance
