4. INTRODUCTION
The effect of heavy metals and spent engine oil in the soil and water are of serious concern
due to their persistence in the environment and carcinogenicity to plants and animal.
Heavy metals are toxic metalloid elements having; (Kennish et al., 1992)
Atomic weight between 63.54 and 200.59.
Specific gravity greater than 4.
High density.
These toxic metalloid includes;
Zn, Pb, Cr, Hg, Cd, Co, Ni etc.

5. Moreover, petroleum derivatives (spilled engine oils) is often observed in
municipal soils creates unsatisfactory conditions for plant growth.
In plants, heavy metal and spilled engine oil results in;
Growth inhibition,
Structure damage and
Decline in physiological and biochemical activities.
5Introduction
6. This RESEARCH concentrates on major mechanic/ scrape dealers sites and industrial areas in
the Cape Coast municipality, where lands have been seriously contaminated by heavy metals
and spilled engine oil ( In Psidu and Ameen Shangari ). This work aim at investigating the
effect of heavy metals and spilled engine oil on plants development (height, girth,
photosynthetic rate, number of leaves & emergence rate) in this areas. Furthermore,
investigating the types of heavy metals present in this soil.

7. PURPOSE OF STUDY
•MAIN OBJECTIVE:
To determine the effect of heavy metal and spilled engine oil on plants development.
•SPECIFIC OBJECTIVES:
i. To characterise the composition of heavy metals and hydrocarbon that are found in polluted soil in Psidu
and Ameen Shangari.
ii. To determine the effect of these heavy metals and spilled engine oil on the height, girth, number of leaves,
photosynthetic rate, and rate of seedlings emergence of cowpea, maize and tomatoes.

8. METHODOLOGY
• Soil samples are collected from Ameen Shangari & Psidu mechanic village(site).
• They investigated to identify the different types of metals ( Ni, Cd, Zn, and Cu ) and composition of spilled
engine oil present, using the electro spectrometer.
• The soil samples are then used to grow different plant species (cowpea, maize and tomatoes) to
investigate it effect on the plant’s development.(height, girth, number of leaves, photosynthetic rate, rate
of seed emergence.

11. •Watering will continued daily at 8:00 GMT.
•The seedling emergence in the treatments and the control experiment will be observed and
recorded.
•Record of seedling height and girth in each treatment are taken weekly for 3 weeks after
planting (3WAP).
•The photosynthetic rate is recorded using PPL
• The seedling height is taken with the aid of a meter rule and it girth by a Vernier caliper.
Mean value of the girth and height in each treatment are taken and record.

13. EXPECTED RESULTS
•I expect ;
To identify heavy metals and composition of spilled engine oil
(hydrocarbons) in the polluted soil.
To observe plants in the loamy soil doing well than plants in the
polluted soil.
To verify the effect of heavy metals and spilled engine oil on
plant development.

14. APPLICATION OF RESULT
•Recommending plants that will be doing well on the polluted soil for phytoremediation/
phytoextractration in polluted areas.
•It will serve as a baseline information for other experiment.
• To make recommendation on proper disposal of spilled engine oil and heavy metal to
avoid high contamination of the environment.
