Evaluation of Air Pollution and Mitigation Using Analysis Technological Approach Factors; A Study of Warri Seaport

Abstract

The transportation sector is one of the largest energy end users, leading to more than 26.6% of all the energy use worldwide and thirty
third in Europe, hence among the principal air polluters with an unbroken increase as projected by the European Commission. The
researchers carried a research work on air pollution and mitigation technologies in Nigeria Seaport with Warri seaport as a focus. To
establish pollution in the area, pollutants such as CO, NO2, CO2, HC and SO2 were critically monitored with air sample analyser monitors,
at source, receptor and Airport Junction Warri as control. The researchers found that the values in wet season was CO (17.30±0.80ppm),
NO2 (0.025±0.002ppm), SO2 (0.028±0.002 ppm), CO2 (370.50±21.00 ppm) and HC (0.015±0.012 ppm) while the values of the
concentration during the dry season was CO(20.20±2.23ppm), NO2(0.019±0.007ppm), SO2(0.025±0.002ppm), CO2(370.50±25.00ppm)
and HC (0.015±0.093ppm) were significantly high. The observed values were found to be significantly different between the two
seasons and higher than those observed in the control group across the seasons as well exceeded the safe allowable limits for gaseous
pollutants when compared with both the Nigerian and international standards. This increase is a concern to Nigeria’s commitments to
implementations of (Annex VI) International Maritime Organization’s (IMO) Convention for the Prevention of Marine Pollution
(MARPOL 73/78) from Ships. However, survey data obtained were analyzed using both descriptive and inferential statistics. The results
from the Factor Anaysis and Principal Component Analysis show that there are air pollution mitigation factors for ocean going and
harbour vessels in Warri seaport, alternative fuel significantly impact on air pollution mitigation in Warri seaport. Recommendations
were made towards adopting appropriate mitigation technologies in Warri seaport
