XVI International Botanical Congess

A study was carried out to determine the effect of heavy metals V, Cu, Mn, Ni and Zn associated with pollution and toxicity in agricultural crops and present in the aviation fuel on Zea mays, Colocassia esculenta and Telfairai occidentalis. A control study was carried out 500m West (Zone B) of the polluted Zone (A). Macro-morphological measurements of the plant parts (leaf, stem and root) were recorded. Analysis using Atomic Absorption Spectrophotometry was carried out on the effluent, soils and on the parts of the plant samples. The amount of the metals in the soil of the two zones, effluent and plants were recorded. Data evaluated statistically established pollution Zone A of which the plants have accumulated higher levels of these metals than those on Zone B. However, extensive subsurface penetration of the Aviation fuel was not observed from analytical data obtained.
