Pollutant emissions in Enugu urban are generally from the combustion of
petroleum products and to a negligible extent, solid waste disposal by open
The quantity of petroleum products consumed within Enugu urban was obtained in
the spot” from the functional fuel stations in the area.
The results showed that Nitrogen Oxide (No) has the highest annual
concentration of 2309.11mg/m3.
next is particulates (1075.8 mg/m3),
hydrocarbons (378.32mg/m3), sulphur
dioxide (1705.8mg/m3), and lastly,
carbon monoxide (85.05mg/m3).
A comparison of pollutant concentrations with WHO quality standards showed that
pollutant emissions within the study area (Enugu Urban) are well within safe
limits although the pollutant concentrations will increase as the population
and economy continue to grow.
Several recommendations were proferred towards the effective control of
pollutant emissions into the study area. these include the improvement of
the efficiency of fuels, the remobilization of automobile engines,
establishment of more road network and traffic decongestion, and the
promulgation of anti-air pollutant laws.
This emission inventory is recommend for the planning and development of this
great metropolitan area called Enugu.

1.1A AIR POLLUTION
people tend to associate air pollution problems with the advent of the
industrial revolution, such problems in one form or another have plagued the
human race for centuries. The earliest pollutants noted in the atmosphere
were probably of natural origin: Smoke, fumes, ash and gases from volcanoes and
forest fires, sand and dust from windstorms in arid regions; fog in humid,
low-lying areas; and natural terpenehazes from pine trees in mountainous
regions were part of our environment long before human induced (anthropogenic)
problems came on the scene.
Indeed, several of the above-mentioned natural problems would surely have
qualified as “air pollution” under this generally accepted definition of
pollution of ambient, or outdoor air:
“Air pollution is the presence in the outdoor
atmosphere of one or more air contaminants
(ie dust, fumes, mist, odour, smoke or vapour)
in sufficient quantities of such characteristics,
and of such duration as to be or to threaten
to be injurious to human, plant, or animal
life, or to property, or which reasonably
interferes with the comfortable enjoyment….
produce, their projected emission of pollutants and the frequency duration, and
relative contribution of pollutant emissions from each source.
Emission Inventories Are Used To:-
1. Plan developments in metropolitan areas.
2. Establish sampling programs and interpret the
results of sampling activities
3. Establish emission standards
4. Provide basic input for simulation models.
5. Estimate air pollutant concentrations with
various metrological conditions.
6. Establish baseline levels of air pollutant
concentrations and to relate these to future trends.
7. Indicate seasonal and geographical distribution
of air pollutants in a study area,
8. Assist in establishing priorities for a control
SCOPE OF RESEARCH
The proposed research is designed to obtain an emission inventory of pollutants
in Enugu metropolis.
Emphasis will be placed on:
1. The identification and classification of the
types of pollutants emitted into the community.
2. The identification and classification of the
sources of these pollutants
3. The determination of the quantity and quality of
the material being handled, processed or burned.
4. The obtaining of emission factors of these
materials and thus computing the rate of emission.
5. The comparism of the inventory with National
ambient air quality standards.
6. The effect of pollutants on human health,
plants, and on materials; and
7. The global implications of air pollution.
Relevant data figures and information for this study were collected from the
Enugu State Environment Protection Agency-ENSEPA (emission factors for solid
waste), by the use of questionnaires through personal interviews from field
surveys and from literature sources.
