Abstract :
The impacts of high concentrations of
particulate matter in ambient air due to incessant
anthropogenic activities have become a tremendous
concern as regards to public health issues associated with
it. This study aimed at assessing some meteorological
parameters and particulate matter concentrations in
ambient air around Bodo and Bori the largest
communities in Ogoni in Rivers State. Okwale and Bera-
Mogho communities, distant from the study areas,
served as control 1 and control 2 respectively.
Meteorological parameters and particulate matter were
determined in-situ using digital portable hand held
monitors. The results showed that wind direction
alternated between South West (SW), North West (NW)
and North East (NE). Relative humidity (%) ranged
from 55.35 to 69.45 with a mean of 64.06±4.96. Ambient
Temperature (oC) ranged from 30.55 to 33.05 with a
mean of 31.74±0.87. Wind speed (m/s) ranged from 3.1 to
4.25 with a mean value of 3.69±0.49. PM2.5, PM10 and
SPM recorded concentrations were below WHO and
NAAQS recommended limits. The results showed that
most control stations showed higher levels of
meteorological parameters and particulate matter than
some of the study locations. This was attributed to
diverse anthropogenic activities such as automobile
activities, illegal artisanal refinery of crude oil and some
domestic activities. The study concluded that the
exposures to particulate matter in the stations are
considered satisfactory and air pollutants pose little or
no risk. The study therefore recommended that further
Studies on other Pollutants including gases should be
monitored in more rural areas around Ogoni
Communities.
