%X Maritime shipping has been a major facilitator of
economic prosperity<span><span><span style=\"font-family:;\" \"=\"\"> <span>throughout the world
and it is likely to grow to meet continued and growing transport needs in both
developed and developing countries. However, global emissions from maritime
shipping ha</span></span></span></span><span><span><span style=\"font-family:;\" \"=\"\">ve</span></span></span><span><span><span style=\"font-family:;\" \"=\"\"> increased considerably, causing depletion of the
ozone layer and most importantly posing threat to lives and coastal environment
through air pollution. This study investigated the constituents of ambient air
in Onne port¡¯s environment in Rivers State of Nigeria. Six air pollutants (O<sub>3</sub> CO, NO<sub>2</sub>, PM<sub>2.5</sub>, PM<sub>10</sub>, and SO<sub>2</sub>) were
critically monitored with hand-held mobile Aeroqual gas monitors, series 500,
at strategic locations within the port¡¯s environment and Eleme Junction (</span></span></span><span><span><span style=\"font-family:;\" \"=\"\">the </span></span></span><span><span><span style=\"font-family:;\" \"=\"\">control). We found that mean concentration</span></span></span><span><span><span style=\"font-family:;\" \"=\"\">s</span></span></span><span><span><span style=\"font-family:;\" \"=\"\"> (¦Ìg&amp;middot;m<sup>3</sup>) of the following pollutants: O<sub>3</sub> (71.776 ¡À 0.726), CO, (19.145 ¡À </span></span></span><span><span><span style=\"font-family:;\" \"=\"\">0.275)
NO<sub>2</sub> (28.145 ¡À 0.965) and SO<sub>2</sub> (36.913 ¡À 0.378) were
significantly high. The particulates (PM<sub>10</sub>, PM<sub>2.5</sub>) also
showed higher mean concentrations of 48.400 ¡À 0.197 and 29.676 ¡À 0.352
respectively. The observed values were found<span> to be significantly higher</span></span></span></span><span><span><span style=\"font-family:;\" \"=\"\"> </span></span></span><span><span><span style=\"font-family:;\" \"=\"\">than those observed in the control group and also exceeded the safe
permissible limits for gaseous pollutants when compared to the World Health
Organization¡¯s (WHO) standards. This exceedance raises questions on Nigeria¡¯s
commitments to implementations of (Annex VI) International Maritime
Organization¡¯s (IMO) Convention for the Prevention of Marine Pollution (MARPOL</span></span></span><span><span><span style=\"font-family:;\" \"=\"\"> 73/78</span></span></span><span><span><span style=\"font-family:;\" \"=\"\">) from Ships. Again, the findings portend ecological
hazards to residents, flora and fauna as elevated levels of these
