The
present study evaluated the computed coefficient of variation in pollutants
concentrations and the exceedance factor (EF) for each criteria pollutant in the
area. According to the results, Eleme area showed that PM2.5 and SO2 have low
dispersion rates in dry season; while TSP, PM10 and PM2.5 have low dispersion
rate in the wet season. In Etche area, PM2.5 and CO have low dispersion rates in
the dry season, while TSP, PM10 and PM2.5 have low dispersion rates in the wet
season. In Ikwerre area, VOCs has low dispersion rate in the dry season, while
TSP, PM10 and PM2.5 have low dispersion rates in the wet season. Also, PM2.5 and
SO2 have low dispersion in the dry season in Obio/Akpor area, while TSP, PM10
and PM2.5 have low dispersion in the wet season. Furthermore, H2S has low
dispersion in the dry season in Oyigbo area, while TSP and PM10 have low
dispersion in the wet season. Similarly, CH4 has low dispersion in the dry
season in Port Harcourt area, while TSP, PM10 and PM2.5 have low dispersion in
the wet season.
Key words:
Dispersion rates implications, seasonal behavioural pattern, air pollutants.
