Abstract :
- The air quality levels of Ihiagwa, Ekeonunwa,
and Amakohia main markets were assessed. The
objectives of this research were to examine those
activities that affect air quality, identify the gases
emitted, measure the concentration, and suggest ways to
minimize them. The study was carried out within three
days and readings were taken morning, afternoon, and
evening in each market. The concentrations of the gases
emitted in the study area were measured using a haze
dust particulate monitor, the Crowcon gas man monitor,
GPS, and MRU AMPRO2000 gas monitor. The
parameters determined were Carbon monoxide (CO),
Ammonia (NH3), Nitrogen dioxide (NO2), Sulphur
dioxide (SO2), particulate matter (PM10), hydrogen
sulfide (H2S), and Methane (CH4). The values of the data
generated were compared with the acceptable limits
given by the Federal Ministry of Environment. The
result obtained shows that the mean concentration of
Carbon monoxide (CO), varied from 0.00-28.80
(7.09±0.60)ppm. Ammonia (NH3) mean concentration
ranges from 0.00-25.00(1.96±0.40)ppm while nitrogen
dioxide (NO₂)mean levels varied from 0.02-
0.41(0.17±0.01)ppm. The average values for sulfur
dioxide (SO₂) were between 0.02-0.83(0.26±0.01) ppm
while hydrogen sulfide (H₂S) average values were from
0.00-2.81(0.38±0.040)ppm. The particulate matter
(PM10) average concentration was 3.48-
36.00(18.9±0.69)mg/m3
. The mean concentration of
flammable gas methane (CH4) was 0.00-
1.50(0.23±0.04)LEL%. It was found that PM10, NO2, and
SO2 all exceeded the limit given by the Federal Ministry
of Environment. This study, therefore, recommends
continuous monitoring of the ambient air quality of the
market to know the evolution of the concentration levels
of these gases for the protection of lives and properties
within the surrounding communities.
