Comparative Assessment Of The Phytoremediation Potential, Growth And Anatomy Of Axonopus Compressus, (Sw.) Beauv. Eleusineindica (L.) Gaertn. And Ipotnoea Batatas (L.) Lam. Grown On Crude Oil Polluted Soil:- Onyebuchi, Chinonyerem O
ABSTRACT
Exploration, production, maintenance,
transportation, storage, vandalization and accidental discharge oil of crude
oil causes contamination of soil and water bodies, thereby altering their
physicochemical properties and nutrient cycle. Crude oil contamination ofsoil
has also been reported to cause anatomical changes in most plants. This study
assessed the phytoremediation potential, growth and anatomy of Axonopus
compressus, Eleusine indica and Ipomoea batatas grown on crude oil contaminated
soil. The experiment was a factorial arrangement (3x4) in a completely
randomized design (CRD). The treatment levels were 0%, 1%, 2%, 3% and 4% crude
oil concentration (Volume/ weight) in the soil. The study observed a
significant (P<0.05) reduction in plant height, number of leaves, stem girth
and fresh and dry weight ofthe three plants grown on the crude oil treated
soils (1%, 2%, 3% and 4%). Some anatomical changes were observed in the treated
leaf, root and stem samples (l%-4% v/w). Disorder in the arrangement of
epidermal cells in the leaves and distortion of cells of roots and leaves were
observed. The heavy metals contents ofthe treated soil, roots and leaves were
significantly (P<0.05) higher than those of the untreated ones. These
effects as observed, increased with increase in level of contamination. Iron
was observed to have the highest content in soil at Oweek (7.42mg/kg in 0% and
11.89mg/kg in 4%) while Nickel had the least content (0.03mg/kg in 0% and 0.38
mg/kg in 4%). Cadmium had the highest percentage reduction by the three plants
(55% in A. compressus, 65% in E. indica and 60% in I. batatas). The metal
contents in the plant parts (leaf and root) differed among the plant species
studied. A. compressus had more accumulation of heavy metals on the roots than
on the leaves. Whereas the leaves of E. indica was observed to accumulate more
heavy metals than its roots. The observed differences in the heavy metal
content ofthe soil and plant parts, as well as the observed anatomical changes
in plants are suggested as possible tool in phytoremediation and
phytomonitoring. The results ofthe study were presented in tables and charts.
However, in order to avoid the reintroduction ofthe heavy metals into the soil
or plants, caution should be applied in the disposal of experimental soils and
plants.
