Air Quality Survey of some locations in the Niger Delta Area
Adoki, Akuro
Abstract
A survey of air quality in Oyigbo (Obigbo) and environs in the Niger
delta area of Nigeria revealed that air quality in the area is affected to varying
degrees by industrial, human and natural activities. Results indicate that SOx values
were below acceptable values for ambient conditions at most of the locations. The
annual average SOx levels ranged between 92.0μg/m3 and 430μg/m3 against the
DPR limit of 150μg/m3. A similar trend was observed for NOx emissions whose
annual averages ranged between 81.0μg/m3 and 150μg/m3. Levels of these
atmospheric contaminants were influenced by season. The average acidity values
(5.63, 5.57, 5.41 and 5.41) of rainwater collected over the monitored period show
rain acidity. The low Conductivity values however indicated non-contamination of
the rainwater.
