Assessment of the contribution of hazardous air pollutants from nigeria’s petroleum refineries to ambient air quality. Part 1

This study investigated the contribution of anthropogenic emission benzene from petroleum refineries to Nigerian’s ambient air quality with view understanding impact production facilities on host airshed. The Activities four existing and 22 proposed in Nigeria were obtained Department Petroleum Resources these combined factors different units at estimate emissions. No-control-measure option (worst case scenario) was assumed because lack information control efficiency refineries. revealed that two one oil-producing cities released a total 10.01 × 1011 tons/year into city, apart additional 2.35 1013 anticipated be three same community. If operated full capacity, estimated stood 5.50 while have capacity releasing 16.73 ton/year. On overall, yearly basis Nigerian airshed 22.24 tons. These concentrations if not checked could lead devastating environmental issues. Some mitigating measures suggested subsequently abate
