Abstract Background Gas flaring in the Niger Delta releases particles which are dispersed over a wide area and have impacts on the environment and human health. The study aimed at assessing the extent of dispersion of PM10 emitted from gas flares in flow stations. Eight selected flow stations in Rivers and Bayelsa states were investigated. The concentrations of PM10 emitted from the flare stacks were monitored 60 m away from the flare stack using a hand-held Met One AEROCET 531 combined Mass Profiler and Particle Counter. Meteorological parameters such as wind speed, ambient temperature and relative humidity were monitored during the sampling campaign. PM10 and meteorological data were analysed for simple and descriptive statistics using SPSS for Windows (version 21.0). Hybrid Single Particle Lagrangian Integrated Trajectory Model (HYSPLIT) was adopted to predict the dispersion of PM10 from the flow stations. Results Results revealed the range concentrations of PM10 from the flow stations (FS 1–8) as 19.9 µg/m3 at FS 1 to 55.4 µg/m3 at FS 8. The maximum concentration of PM10 at FS 8 was higher than the World Health organisation limit of 50 µg/m3. The dispersion of PM10 emitted from FS 1, 4 and 7 in April 2017, had a fitting spread over Port Harcourt City. Conclusions The modeling results revealed dispersion of PM10 from the flow stations to 14 states in Nigeria. This suggests possible detrimental health and environmental effects of PM10 on residents in the identified states.

This study was conducted to assess the outdoor air quality of some urban slums in Port Harcourt. Six sampling sites were selected, from the Port Harcourt urban slums; two sites from each slum represented with a suffix 1 or 2.  The slums are designated Marine base (#1 and #2), RSU BG, Obudu 2, Bundu (#1 and #2). The air quality was analyzed using portable handheld air quality analyzer and the microbiological parameters were determined by standard cultural method. The study revealed that the sampled sites were laden with bacterial and fungal species. namely; Klebsiella sp., Micrococcus sp., Escherichia sp., Pseudomonas sp., Baccilus sp., Aeromonas sp., Streptococus sp., Serratia sp., Aerococcus sp., Proteus sp. Penicillium sp., Fusarium sp., Candida sp., Aspergillus sp., Mucor sp., Rhizopus sp. and Tricorderma sp. Highest obtained noise level was at Marine base 1 which was  66 db, highest relative humidity of 54.8% at RSU BG, CO2  (ppm) values of 4.8, 80, 796, 850, 638, 698 for Marine base 2, Marine base 1, Obudu 2, RSU BG, Bundu 1 and Bundu 2 respectively. The values for NO2 (ppm) was (0.05, 0.053, 0.071, 0.022, 0.035, 0.023), suspended particulate matter (ppm) was (7.1, 8.7, 9.5, 9.5, 6.2, 6.2), SO2 (ppm) was (0.42, 0.15, 0.50, 0.34, 1.26, 0.41) CO (ppm) was (4.8, 1.7, 2.2, 3.0, 3.9, 3.6) and volatile organic compound (ppm) was (1.0, 1.1, 0.9, 75 and 1.2). This study has shown that Port Harcourt urban slums are experiencing some degree of contamination not acceptable for healthy living that requires attention to curb. These areas require all-round improvement in sanitation.   M Give one sentence on methodology.
