Implication of Roasting Goats with Tyre on Human Health and the Environment in Abakaliki, Ebonyi State, Nigeria

Friday AC and Nwite JN

Implication of roasting goats with tyre on human health and the environment in Abakaliki metropolis, Ebonyi State was reviewed in this study. Tyre has 45.49, 40, 0.23 and 1.17% composition for carbon black, zinc oxide, wax and sulphur toxic materials which could pose health threats to human being and the environment. Most of the butchers in Abakaliki and its environs roast slaughtered goats with scrap car tyres. Scraped soot from the roasted goats have significant (P<0.05) high levels of 5.40, 96.10, 38.03 and 61.00 mg kg-1 heavy metal residues for pb, Zn, Cu, and Fe which are washed into the soil, water bodies and air that cause their contamination. These heavy metals concentrations are higher than maximum permissible limit (MPL). Appropriate laws should be made and enforced in Ebonyi State to stop local butchers from using tyres as roasting materials. Scraped soot should also be disposed off safely as is done elsewhere in order to reduce the risk of contamination of soils, water bodies and air with heavy metals in Abakaliki metropolis of Ebonyi State.
